Aethercomm Part Number SSPA 0.7-0.9-50 is a high power, L Band, Solid State Power Amplifier that operates from 700 to 900 MHz.  The P1dB at 25C is 50 watts minimum.  The saturated output power is 60 watts typical at 25C.  Minimum small signal gain is 45 dB. Noise Figure is 7 dB typical at 25C. Input VSWR is 2.0:1 maximum. Output VSWR is 2.0:1 maximum.This unit is equipped with Aethercomm’s proprietary DC switching circuitry that enables and disables the DC-DC circuitry in 1000 nSec typical on this unit. Standard features include reverse polarity protection, output short and open circuit protection, and an integrated DC-DC converter with over/under voltage protection.  This power amplifier operates from a +12 Vdc power supply with a class A bias of typically 18 amps. DC current with the PA disabled is 250mA maximum. This amplifier operates from -40C to +65C base plate temperature. 

This SSPA is ideal for L Band Communication Systems that require high reliability, excellent linearity and high power in a rugged and compact module.  Standard housing size is approximately 6.5 X 8.0 X 1.0 inches. Mounting is accomplished via six through holes in the housing.  SMA female connectors are standard on the RF input port. An SMA female connector is standard on the output port.  DC connections are accessible via a DC feed through capacitor.  The CMOS Switching command is applied via a DC feed through capacitor.

This is an example of an Aethercomm standard product. Aethercomm designs and manufactures high performance, high power CW or pulsed SSPA’s for commercial, military and satellite communications customers.
