Ku-Band Solid State Power Amplifier Offers 40+ Watts


Pulsed SSPA for commercial, military and satellite applications

RFMW, Ltd. announces design and sales support for a Ku-band solid state power amplifier. The Aethercomm SSPA 16.75-20.25-40 is a high power, Gallium Nitride (GaN) solid state power amplifier that operates from 16.75-20.25 GHz and delivers a minimum output power of 40 Watts.

Using GaN technology, it’s optimized for high shock and vibration requirements supporting operation from -40°C to +70°C base plate temperature. Typical SSPA 16.75-20.25-40 power gain is 46 dB minimum. Input and output VSWR is 2.0:1 maximum. This SSPA can be blanked on and off in less than 10.0 uSec. OIP3 is 51 dBm minimum.


DC and logic connections are accessible via feed through pins. The RF input connector is an SMA female and is WR-51 waveguide.

Operating from a +28 Vdc power supply, standard features include reverse polarity protection and output short and open circuit protection along with an over-temperature shut down feature to protect the amplifier.

It is packaged in an enclosure that is optimized for high shock and vibration requirements and the housing volume is approximately 4.0″ (W) x 5.0″ (l) x 2.0″ (H).
