This voltage controlled programmable attenuator features a 63 dB dynamic range in 1 dB steps. Model 631-031-063 is rated 1-Watt 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. The supply voltage +12 Vdc at 30 mA nominal per section resulting in 10 milliseconds switching speed. The 50 Ohm attenuator has an operating frequency range of DC – 2200 MHz, maximum VSWR is 1.40:1 and insertion loss is 3.5 dB maximum. Other impedance and connector options are also available.
