Link Microtek is selling a switchable Ka/Q-band microwave power module (MPM) that provides highly compact power-amplifier functionality for defence and aerospace applications where size and weight are key considerations. Designed and manufactured by L-3 Electron Devices, the M2837 module delivers more than 100W of saturated CW power at Ka-band frequencies from 29.5 to 31.0GHz and over 80W at Q-band frequencies from 43.5 to 45.5GHz.
Applications include satellite communication uplinks in unmanned aerial vehicles (UAVs).
The 28VDC-input MPM combines a solid-state driver amplifier, a miniature helix travelling wave tube and a power supply in a single rugged package measuring just 248 x 216 x 38mm and weighing only 3.3kg. It utilises a single 2.4mm coaxial connector for the RF input and a WR24 waveguide for the output.
Fully compliant with the MIL-STD-461 electromagnetic compatibility standard, the M2837 unit is equipped with a forward and reverse power coupler and offers both RS485 and TTL signalling for status monitoring and control.
The new MPM has a wide operating temperature range of -40 to 85degC and can be specified with an optional forced-air heat exchanger if required.
