TMD Introduces a Microwave Power Module for Radar, EW and Communications System Applications

TMD Technologies, a leader in RF, microwave, and high-power amplifiers has introduced the PTXM9754, an ultra-compact, modular MPM (Microwave Power Module). This unit is ideally suited for high-performance military radar, EW/EA/ECM and communications systems. It utilizes a ‘super-mini’ TWT (travelling wave tube), a solid-state pre-amplifier, and an optimized high density switched-mode power supply to form a single ‘drop-in’ amplifier block. This design provides an FFF (form, fit, function) equivalent to existing 6-18 GHz MPMs installed across many shipboard, airborne, and ground-based systems.

The PTXM9754 features a broadband 6 to 18 GHz TWT capable of providing 100 W CW minimum across the band. It incorporates a high-speed focus electrode modulator to allow operation at high PRFs, making it ideal for pulsed applications such as in ECM and radars.  A low gain TWT working with a low noise solid state preamplifier provides optimum noise performance. The prime power requirement is 28 V DC.

As well as being of low weight and small size, the PTXM9754 features excellent thermal management. Its high electrical efficiency means that the minimum of cooling is required – resulting in high reliability operation over a wide temperature range. Also, by virtue of its fully encapsulated HV section, the unit will operate at high altitudes and humidity.

Tom Curtin, VP Sales and Business Development, TMD Technologies, stated that this advanced unit has been designed in direct response to unprecedented demand for a drop-in replacement as an alternative to existing 6-18 GHz 100 W (minimum) MPMs. Following a high-priority development project at their design facility in London, UK, TMD has produced a superior high-performance amplifier, built to stringent specifications, and readily available to support existing and new DoD programs.
