For defense and communications applications that require high power, L-3 Electron Devices offers two microwave power modules (MPM) that lead in size, weight and power (SWaP). Integrating a solid-state driver, TWT and power supply, each MPM is housed in a compact package designed for rugged military environments.
The M1245 MPM provides
200 W minimum output power across 6.5 to 18 GHz, with spurs no greater than −50 dBc and a maximum noise power density of −35 dBm/MHz. The power amplifier’s small-signal gain is 60 dB minimum. The RF input connector is SMA female, and the output interface is WRD-650 double-ridged waveguide. The MPM operates from a +270 VDC supply, per MIL-STD-704E, and has 900 W maximum power dissipation. The housing size is 8.5" × 9.75" × 1.5".
The M2842 MPM is designed to provide 60 W minimum output power from 18 to 40 GHz and 100 W minimum from 20 to 36 GHz. Spurs are no greater than −45 dBc, the maximum noise power density is −30 dBm/MHz and the minimum small-signal gain is 40 dB. The RF input connector is a 2.9 mm female, and the output interface is WRD-180 double-ridged waveguide. This MPM operates from a +28 VDC supply and dissipates a maximum of 400 W. The housing size is 8.5" × 9.75" × 1.75".
Both MPMs have individual on/off controls for supply voltage and RF, with visual indicators for warm-up, high voltage and a fault condition. The units are cooled by conduction and can operate from −40° to +85°C.
