PERFORMANCE

The Ku-Band Transmitter Upconverter Assembly is a component of an airborne high-speed data transmission system. This assembly provides frequency translation of an L-band input to a Ku-band output, which drives a Solid State Power Amplifier Assembly. It is DO-160D qualified and features digital gain control and compensation for the input coaxial
cable.
