Phase2 Microwave Ltd started Life as Phase Devices Ltd in 1983. Phase Devices was acquired by Comdev International and given the name of Comdev Wireless and focused on two business areas, Satcomms systems based in Lostwithiel, Cornwall and Mobile Comms, Base Station Equipment based in Luton, Bedfordshire.

When Comdev Wireless was sold to Mitec Telecom, many of the Phase 2 staff who worked together at Phase devices started a new company, namely Phase2 Microwave Ltd.

Phase2 have a special strength in filter design, Lumped Element, Combline, Interdigital, Cavity and Waveguide, based on 30 years experience with many successful Aerospace, Defence and Commercial designs.

WG17 SATCOMS LOWPASS                                               q998 tps ermes 3q088 low pim diplexer 4

We supply a broad range of specialised microwave components, especially high power and high directivity loop-couplers. We have also designed X Band phased array feeder networks with precise amplitude and phase control.

Leaders in the design and manufacture of intermod test sets down to -180dBc for ground testing of satellite systems and other communications equipment.

                                                                                           q088 low pim diplexer 4

Developed high power bandpass and lowpass filters for radars at S, C and X band and specialise in very high power devices.


 With the advent of the LTE bands at 2.6GHz we have developed a range of radar protection filters and conversely filters to protect the LTE bands from the radar.
We are currently working on filters in the 4.5G and 5G frequencies.
