The SCA series of solid state power amplifiers offer high reliabillity and full set of standard features. Designed to be driven from a *0W FM Broadcast Quality Exciter, the SCA****-FM series will deliver up to ***0W output in a compact *-U EIA *9” rackmount cabinet. Standard features include automatic power control, predictive automatic fan fail detection, VSWR monitoring and automatic foldback, graceful power degradation, serial data communications and control, analog outputs for power, voltage, current (soft configurable), complete front panel information screens. The amplifier features SCA firmware which allows for operation even in the event of circuit fault. This includes damaged power supply, damaged power amplifiers, damaged fans, blocked airflow, VSWR problems. The power amplifier is based upon sixth generation, **8V DC Silicon LDMOS technology which operates at a DC efficiency of *8% typical! In a standard configuration, this translates into better than *5% system efficiency. Four amplifiers are combined with an isolated broadband combiner, and two power factor correct switching power supplies provide system power. The chassis uses our oversized military grade heatsink capable of operation beyond most amplifiers. This bonded fin heatsink will allow full power operation at altitude up to *5 °C. Because all RF amplifier sections are sealed from external airflow, outside cooling air may be used saving costly air conditioning requirements. The entire system is built in a modular fashion with all high power components placed in the bottom of the amplifier and power supply, control, low power components in the top of the amplifier. The amplifier maintains an ***** (mean time to repair) of better than *0 minutes. For common circuit faults, typical repair time is *5 minutes, and no soldering is required!
