Microwave Power Modules


With expertise in both traveling wave tube (TWT) and solid state technology, CPI TMD has your needs covered.

CPI TMD began developing TWT-based microwave power modules (MPMs) in the early 2000s under the name TMD Technologies Ltd. Since then, CPI TMD has produced a wide variety of custom products. Most recently, CPI TMD began offering solid state MPMs, which provide technical advantages for particular specifications and applications.

Each of CPI TMD's TWT-based units is comprised of a compact power supply and mini TWT, combined into an ultra-compact, lightweight "drop-in" amplifier block. This simplifies system design and installation, increases reliability and minimizes safety hazards. The units also feature high electrical efficiency and excellent thermal management. Performance is factory set, removing the need for any user adjustments in the field and, if necessary, permitting easy field replacement of the complete unit. The product range covers S-band to Ka-band, and includes continuous wave (CW), pulsed and CW/pulsed units of extremely compact design. At only 1.7 kg with over 110 W output power, the PTXM1000 is believed to be the market’s highest power density MPM.

CPI TMD's solid state units incorporate the latest advances in 0.25 µm GaN MMIC (monolithic microwave integrated circuit) technology and low-loss power combiners; optimized for electronic warfare (EW) applications.

Microwave Power Modules for Radar, EW & Communications applications, have the following features:
  • Ultra-compact “drop-in” microwave amplifier blocks pulsed or CW operation
  • External TWT connections are eliminated
  • Safe and easy installation
  • High reliability
  • Excellent thermal management
  • S-band to Ka-band frequency range
  • Particularly suitable for airborne applications or where space and weight are critical
  • TWT-based and solid state versions available
  • ITAR-free versions available
CPI TMD has expanded its investment in the solid state power amplifier (SSPA) MPM space through a partnership with Diamond Microwave Ltd. CPI TMD now has SSPA MPMs available with various output power options from UHF through Ku-band.
