CPI sells several categories of VEDs, including:
- Klystrons and gyrotrons: Klystrons are typically high-power VEDs that operate over a narrow range of frequencies, with power output ranges from hundreds of watts to megawatts and frequencies from 500 kilohertz (KHz) to over 30 GHz. CPI produces and manufactures klystrons for a variety of radar, communications, medical, industrial and scientific applications. Gyrotron oscillators and amplifiers operate at very high power and VHFs. Power output of one megawatt has been achieved at frequencies greater than 100 GHz. These devices are used in areas such as fusion research, electronic warfare and high-resolution radar.
- Helix traveling wave tubes: Helix traveling wave tubes are VEDs that operate over a wide range of frequencies at moderate output power levels (tens of watts to thousands of watts). These devices are ideal for terrestrial and satellite communications and electronic warfare applications.
- Coupled cavity traveling wave tubes: Coupled cavity traveling wave tubes are VEDs that combine some of the power generating capability of a klystron with some of the increased bandwidth (wider frequency range) properties of a helix traveling wave tube. These amplifiers are medium bandwidth, high-power devices, with power output levels that can be as high as one megawatt. These devices are used primarily for high-power and multi-function radars, including frontline radar systems.
- Magnetrons: Magnetron oscillators are VEDs capable of generating high-power output at relatively low cost. Magnetrons generate power levels as high as 20 megawatts and cover frequencies up to the 40 GHz range. CPI designs and manufactures magnetrons for radar, electronic warfare and missile programs within the defense market. Shipboard platforms include search and air traffic control radar on most aircraft carriers, cruisers and destroyers of NATO-country naval fleets. Ground-based installations include various military and civil search and air traffic control radar systems. CPI is also a supplier of magnetrons for use in commercial weather radar and for use in industrial applications, including industrial heating, cooking, material processing and cargo screening applications. Other potential uses for magnetrons include high-power microwave systems for disruption of enemy electronic equipment and the disabling or destruction of roadside bombs and other IEDs.
- Cross-field amplifiers: Cross-field amplifiers are VEDs used for high-power radar applications because they have power output capability as high as 10 megawatts. CPI’s cross-field amplifiers are primarily used to support radar systems on the Aegis weapons systems used by the U.S. Navy and select foreign naval vessels. CPI supplies units both for new ships and for replacements on existing ships.
- Power grid devices: Power grid devices are lower frequency electron devices that are used to generate, amplify and control electromagnetic energy. These devices are used in commercial and military communications systems and radio and television broadcasting. CPI also supplies power grid devices for the shortwave broadcast market and for MRI and other applications for the medical market. CPI’s products are also widely used in equipment that serves the industrial markets, such as textile drying, pipe welding and semiconductor wafer fabrication.
- Microwave transmitter subsystems: CPI’s microwave transmitter subsystems are integrated assemblies built primarily around CPI’s VED products. These subsystems incorporate specialized high-voltage power supplies to power the VED, plus cooling and control systems that are uniquely designed to work in conjunction with CPI’s devices to maximize life, performance and reliability. Microwave transmitter subsystems are used in a variety of defense and commercial applications. CPI’s transmitter subsystems are available at frequencies ranging from one GHz all the way up to 100 GHz and beyond.
- Satellite communications amplifiers: Satellite communications amplifiers provide integrated power amplification for the transmission of voice, broadcast, data, Internet and other communications signals from ground stations to satellites in all frequency bands. CPI provides a broad line of complete, integrated satellite communications amplifiers that consist of a VED or solid-state microwave amplifier, a power supply to power the device, RF conditioning circuitry, cooling equipment, electronics to control the amplifier and enable it to interface with the satellite ground station, and a cabinet. These amplifiers are often combined in sub-system configurations with other components to meet specific customer requirements. CPI offers amplifiers both for defense and for commercial applications. CPI’s products include amplifiers based on helix and coupled cavity traveling wave tubes, klystrons and solid-state devices, operating at frequencies ranging from microwaves to millimeter waves.
- Receiver protectors and control components: Receiver protectors are used in the defense market in radar systems to protect sensitive receivers from high-power signals, thereby preventing damage to the receiver. CPI has been designing and manufacturing receiver protector products for more than 65 years. CPI believes that it is the world’s largest manufacturer of receiver protectors and the only manufacturer offering the full range of available technologies. CPI also manufactures a wide range of other components used to control the RF energy in the customer’s system. CPI’s receiver protectors and control components are integrated into prominent fielded military programs. As radar systems have evolved to improve performance and reduce size and weight, CPI has invested in the latest solid-state technology to develop and manufacture the microwave control components to allow us to offer more fully integrated products, referred to as multifunction assemblies, including receivers, upconverters pulse compression assemblies, low noise amplifiers, switches and oscillators, as required by modern radar systems.
- Medical x-ray imaging systems: CPI designs and manufactures x-ray generators for medical imaging applications. These consist of power supplies, cooling, control and display subsystems that drive the x-ray equipment used by healthcare providers for medical imaging. The energy in an x-ray imaging system is generated by an x-ray tube, which is another version of a VED that operates in a different region of the electromagnetic spectrum. These generators use the high-voltage and control systems expertise originally developed by us while designing power systems to drive CPI’s other VEDs. CPI has introduced mobile x-ray generators and x-ray generators with imaging processing systems to assist its customers in their migration from film-based radiology systems to digital radiology systems. CPI also provides the electronics and software subsystems that control and tie together much of the other ancillary equipment in a typical x-ray imaging system.
- Antenna systems: CPI designs and manufactures antenna systems for a variety of applications, including radar, electronic warfare, communications and telemetry. Along with a variety of antenna types, including phased array, edge and tilt scanning antennas, conformal electronic scanning antennas, stabilized shipboard tracking antennas and CPI’s trademark FLAPS (Flat Parabolic Surface) antennas, the antenna systems also include the highly efficient harmonic drive pedestals used to support them. The antenna systems used on airborne, shipboard and ground-based platforms are designed to enable high performance, high data rate transmission at frequencies ranging from one GHz to 100 GHz.
- Advanced composite radomes, reflector antennas and structures: CPI designs and manufactures advanced composite radomes, reflector antennas and structures for defense aerospace and naval applications and for commercial aerospace applications. A radome is a weatherproof structure that encloses and protects a microwave antenna without interfering with the antenna’s ability to transmit or receive electromagnetic signals. CPI’s products are customized for each system and application based on the operational frequency, RF-performance, structural and environmental requirements of the end system. CPI’s products cover frequencies up to 95 GHz.
- Solid-state products: CPI designs and manufactures a wide variety of solid-state products for a number of applications, including defense, communications and scientific applications. These products include, but are not limited to, power amplifiers, upconverters, pulse compression assemblies, voltage controlled oscillators, high power solid-state switches, phase shifters, PIN diode attenuators, limiters and low noise amplifiers. In the communications market, these products are specifically designed to address the demanding needs of the steadily growing commercial and government satcom on the pause/move (SOTP/M) applications, which are providing highly mobile interconnectivity on a global basis. CPI’s solid-state products extend from microwave to state-of-the art millimeter-wave frequencies, and are based on both gallium arsenide and leading-edge gallium nitride technology so that customers may employ the optimal solution for these applications.
