whatever the application.

Amplifiers for every application

AMETEK CTS has been designing and manufacturing RF amplifiers for over 30 years. From our design and manufacturing facilities in the UK, Switzerland and Germany, our customers can be confident they will always get an RF amplifier solution that is correctly matched to their requirement. Our know-how and experience will ensure you get a solution that is optimized to meet your application requirements at the right cost. 

Under the product names of Teseq, IFI and Milmega, we have produced RF amplifiers suitable for the widest range of applications including: 


Flexible combination from 10 KHz to 40 GHz.  Power levels up to 11KW (pulsed TWT) for radiated susceptibility test system applications covering, commercial, medical, automotive, aerospace, and military EMC standards.

Class A solid state amplifiers developed in parallel to meet 5G spectrum bandwidth and modulation needs. Ideal for testing, infrastructure component characterization, linearity measurements including intermodulation, ACPL, EVM and multitone plus high signal level reliability.

EW & Radar
Applications Including search and rescue, airborne early warning (AEW), ground mobile air defence, anti-submarine warfare (ASW), terrain-following radar (TFR), maritime patrol aircraft (MPA). Pulse and CW for shipborne military environments.
