This is a Ka-Band Block Up-Converter (BUC) with an integrated IF Linearizer up-converts an IF Band signal from 1-2 GHz to 29-30 GHz or 30-31 GHz. The output band is selected via an RS-422 command, as is gain control, mute, and reference frequency selection. The RS-422 interface also allows reporting of the input power to the mixer, internal temperature, and local oscillator (LO) lock detect.
This BUC uses a fully integrated IF Linearizer ASIC which can be used to linearize a SSPA. The achievable improvement in linearity depends on the type of SSPA, modulation scheme, and symbol rates used. Feedback of the RF signal is required to utilize the RF linearizer: approximately +10dBm is required at the RF feedback input.
This BUC has been optimized for use with the TSA-214145 GaN SSPA.
