The PTXM9754 from TMD Technologies is a Microwave Power Module (MPM) that operates from 6 to 18 GHz. It has an integrated Travelling Wave Tube (TWT), a solid-state preamplifier, and an optimized high-density switch mode power supply to produce a single "drop-in" microwave amplifier block. The integration of TWT and Power supply simplifies the system designer’s task by eliminating TWT interconnections (and their associated safety and reliability hazards). It delivers a saturated output power of 100 W with a small signal gain of over 58 dB. A low gain TWT is specified together with a low noise solid-state preamplifier to provide optimum noise performance. The device requires a DC supply voltage of 28 V and consumes up to 540 W of power.
The MPM includes a high-speed focus electrode modulator to permit operation at a high PRF (Pulse Repetition Frequency). This makes the MPM ideal for pulsed applications such as ECM and Radars. It is factory adjusted to optimize TWT performance. No user adjustments are required, simplifying replacement and reducing replacement times in the field. The device can be configured to incorporate a variety of TWT models, allowing the user to specify frequency and peak power parameters. A control interface is incorporated which allows remote operation and status monitoring, providing diagnostic outputs for BIT purposes.
The PTXM9754 is available in a module that measures 203.2 x 196.85 x 35.6 mm with an SMA (F) connector at the input and a TNC (F) connector at the output and is ideally suited for high-performance military radar, EW/EA/ECM and communications systems.
