The Series 1200 amplifier is a solid state design used in applications utilizing high power and FPGA control. Typical models include input/output monitoring with mnemonic fault indicators and a continuous data stream of forward power, VSWR, and temperature information. The amplifier is protected against excess duty cycle and pulse width by means of proprietary software control. The protection is independent of the type of waveform being processed. Input modulation is accomplished using a TTL or CMOS compatible signal. Lower power models are in use as drivers for L-Band Radar Systems. Higher power models are used as output stages. Multiple units can be paralleled to provide output power levels up to several kilowatts (KW). Phase accuracies are maintained to ±3 degrees.
