Compact Digitally Controlled Linearizer Modules for Use in TWTAs Power Amplifiers
The BLFE-6000S/8000S/14000S/18000S/28000S/45000S series offer a complete frontend and a predistortion linearizer in a single compact module. They are intended to be installed within TWT and Klystron high power amplifiers. SSPA versions are also available. They provide high gain (>40 dB) with a wide range attenuator (>30 dB), analog or digital control, and optional power detection and mute control. 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.
