Model 631-031-063, a voltage controlled programmable attenuator, features a 63 dB dynamic range in 1 dB steps. It is rated 1W average input power and has SMA female RF connectors. Attenuation accuracy is +/-0.5 dB or 2% of programmed and is controlled via solder terminal connectors. Supply voltage is +12 Vdc at 30mA nominal per section, resulting in 10 milliseconds switching speed. The 50 ohm attenuator has an operating frequency range of DC to 2200 MHz, maximum VSWR is 1.40:1, and insertion loss is 3.5 dB maximum.
