TMD Technologies Limited (TMD) will introduce two new TWT based microwave power modules (MPMs) – the PTX8110, 6-18 GHz, 200 W unit and the PTX8815, Ka-Band, 1100 W unit – at DSEi 2017, which will take place at ExCeL London, UK from 12 to 15 September.

The new PTX8110 operates from 6 to 18 GHz at 200 W and with its compact design, is easily integrated into those high performance EW and radar systems requiring higher power. Comprising a high power helix travelling wave tube (TWT) and switched mode power supply, the PTX8110 forms a single ‘drop-in’ microwave amplifier unit without the need for potentially unreliable high voltage TWT interconnections.

A low gain TWT is specified together with a low noise Solid State Preamplifier to provide optimum noise performance. It features high electrical efficiency, needs a minimum of cooling and operates over a wide temperature range – at high altitude and high humidity,

The new PTX8815 TWTA is designed for Ka -Band radar applications such as naval fire control. Featuring broadband capability, covering 34 GHz to 36 GHz, it offers a peak power of over 1100 W in the mid-band and 600 W at the band edges with a maximum duty of up to 12%. This top class TWTA is the answer to high fidelity radar requirements for low close-to-carrier phase noise and spurious performance. This development follows the launch in 2016 of the PTX8807 Ka-Band, 200 W MPM which is aimed primarily at EW applications and which will also be featured at this year’s show.

“DSEI is always a major event for us,” said Jane McAlister, TMD’s Sales and Business Development Director, “and we always field the strongest sales team. The exciting mix of delegates, including country state ministers, international armed forces decision makers, home security representatives and key industry players from the private sector has resulted in more trade contacts for us than at any other exhibition – and being part of the ADS UK Pavilion is a bonus in itself.”

Emphasizing its capability in advanced solid state innovation, 255TMD will also be exhibiting (on Stand S3) the PTS6900 MPM, which employs the latest GaN MMIC technology. This MPM is optimized for EW/ECM systems, and operates over the 2 to 6 GHz range with a power output of 150 W and adjustable 55 dB gain. It features a very high predicted MTBF in an airborne uninhabited fighter environment.

Offering very low volume and weight, TMD’s TWT based PTXM Series is designed for airborne radar, EW and communications and is ideal for UAVs. The units operate over the 4.5 to 18 GHz range with output powers up to 140 W. Incorporating mini TWTs and super efficiency packaging.
