MELVILLE, N.Y., 8 Feb. 2016. Comtech PST Corp. in Melville, N.Y., is introducing a VHF/UHF wideband high power RF amplifier in one LRU. This class AB linear design operates over 20 to 500 MHz frequency range and is for research laboratories or where reliable & accurate linear power is required.
The amplifier is designed to deliver exacting high power into high voltage standing wave ratio (VSWR) antenna loads, is electronically self-protected and supports several modulation schemes.
Power accuracy is maintained through user controlled step attenuators and a fast 100-microsecond digital ALC loop. The front panel display supplements the operator's remote control features with operational status with forward and reverse power reporting.
The designs are fault tolerant because of multiple RF modules final stage combining techniques. Internal built-in test helps troubleshoot to the faulty component. The LRU also houses a SPDT dummy load switch as well as an efficient modular AC power supply.
