Electromechanical Programmable Attenuator

BroadWave Technologies model 651-031-127 is a voltage controlled programmable attenuator originally developed for test applications. This 50Ω attenuator has a frequency range of DC - 2200 MHz. Attenuation range is 1 - 127 dB in a 1 dB steps with attenuation accuracy ± 0.5 dB. Insertion loss is 4.5 dB maximum while VSWR is 1.50:1 maximum. Input power is 1 watt average with supply voltage +12 Vdc @ 30 mA nominal per section. The RF connectors are SMA female and the control solder terminals feature feed-thru capacitors to prevent leakage. Other impedance, attenuation ranges and RF connector types are available.
