TWT based MPM for defence systems on display at EW Europe 2017

At EW Europe 2017, manufacturer of professional microwave and RF products, TMD Technologies (TMD), will be showing its new line of PTX8807 Ka band TWT (Travelling Wave Tube) based MPMs (Microwave Power Modules) for high performance EW and radar systems. Also on show on stand 23 will be TMD’s solid state PTS6900 and TWT based PTXM Series MPMs.

Stuart Love, TMD’s Senior Sales Manager, UK and Europe, said: “We are very pleased to be back at EW Europe again – this time on our own turf, in London! Organised under the auspices of the high status Association of Old Crows, it allows us to participate in one of the most focused events in the industry – where we will have an ideal platform to show our latest products to the world’s defence and security community and where, in the light of current and emerging threats, the future of EW and ECM operations in the free world will be explored to the full."

“Furthermore”, said Steve Humphries, TMD’s Territory Manager, Europe and Africa, “the hugely popular Networking Evening unites exhibitors, delegates, visitors and VIPs in a social environment and allows us to make important contacts with people that we perhaps would not see during the busy working exhibition day.”

PTX8807 – counter measures against threats
TMD’s new line of TWT based MPMs is exemplified by the PTX8807. Operating in the technically challenging 30-40GHz Ka band, this 200W output MPM addresses the solution to providing effective counter measures against operating systems emerging in Ka frequency range – such as missile threats.

The PTX8807 is easily integrated into EW and radar systems, and comprises a high power helix TWT and switched mode power supply to form a single drop-in unit without the need for potentially unreliable high voltage connections. It requires minimum cooling, operates over a wide temperature range, at high altitude and in high humidity, and is easily incorporated into a variety of airborne platforms.

The MPM also features remote operation and status monitoring.

PTS6900 – high MTBF in uninhabited fighter environment
The solution for fast integration into EW/ECM systems - airborne or ground based - this latest solid state PTS6900 MPM from TMD employs advanced GaN MMIC technology and operates over the 2-6GHz range with 150W output and adjustable 55dB gain.

The PTS6900 provides instant start time, fast mute time, low output noise, and functions in the face of inadvertent output mismatches (VSWR). It boasts a very high predicted MTBF of 30,000 hours in an uninhabited fighter environment! Furthermore it is ITAR-free – a distinct advantage to non-US customers.

PTXM series – suitable for UAVs
TMD’s PTXM series ultra compact MPMs are designed for airborne radar, EW and communications, and are suitable for applications where low volume and weight are critical – as on UAVs. They operate over the frequency range 4.5-18GHz, with power outputs up to 140W, and incorporate mini TWTs and super efficiency packaging to offer perhaps the highest power density on the market today.
