Agilent/Keysight 493A

The Agilent/Keysight 493A is a microwave power amplifier operating from 4 GHz to 8 GHz, delivering 1 watt of output power with 30 dB gain. Designed for 50 ohm systems, it features Type N female connectors for input and output and integrates amplitude modulation capability across DC to 500 kHz (3 dB). The amplifier accepts modulation inputs of greater than -20 V peak to reduce RF output by more than 20 dB, providing flexible signal conditioning in test and measurement setups. With a noise figure greater than 30 dB, the unit measures 5.5 x 16.75 x 18.375 inches and weighs 33 lbs, fitting standard 19-inch rack configurations with modest footprint requirements.
