6, 8 GHz, 4 Channel Programmable Attentuator

QPA8, PA8 - GigaBaudics Co. (Giga)

This device has low impedance mismatch, high bandwidth, wide dynamic range and is capable of rapid state change. The QPA8 can be an attractive alternative to either the manually operated microwave attenuator switches, which are expensive and are switched very slowly, or the relay attenuators which are expensive and wear out quickly. Attenuation is controlled in standard steps of 0.0625 dB. The 10 bit programmable range results in the full 210=1024 steps yielding a dynamic range of 0 to 63.9375dB. Non-standard custom step sizes are available.
