Class AB Linear Amplifiers: Series BHE

The new Series BHE Amplifiers from Comtech PST are arranged in a wide variety of configurations with operating frequency ranges from 20 to 1000 MHz. These AB linear amplifiers are designed to provide load VSWR protection by way of an electronic power output turndown system employing negative feedback techniques. The system is self-correcting as a function of load VSWR to infinity, at any phase angle with a typical response time of 60 µsec.

Series BHE amplifiers feature input/output overdrive protection due to an included leveling loop system. Other characteristics include a power output range from 100 to 1500 W, built-in test diagnostics, field-replaceable modules, graceful degradation, and high efficiency switching power supplies. Available product options include mechanical or solid state switched filter assemblies, forward/reflecting sample ports, noise quieting, rack mounting slides, and other custom specifications. The series BHE wide bandwidths are ideal for multi-octave, frequency-agile systems in EW/ECM systems, communication systems, AM/FM transmitter boosters, TWT replacement, RFI/EMI testing, and high power calibration testing.
