Compact Digitally Controlled Linearizer Modules for Use in TWTAs Power Amplifiers

LBUCs, linearized block upconverters, are available for X, Ku and Ka and Q-band. They directly drive high power amplifiers (TWTAs, KPAs, SSPAs) from an L or X-Band signal source.  LBUCs provide high gain (>40 dB) with a wide range attenuator (>35 dB), analog or digital control, and an external or internal reference.  They typically give a 4X power increase with multicarrier traffic and advanced digital modulation. Alignment is done at the time of installation and typically requires less than 10 minutes.
