The PDVAN-8018-60-8-OPT25dBM from Planar Monolithics Industries is an 8-bit Digital Attenuator that operates from 8 to 18 GHz. It provides an attenuation range of 60 dB with a 0.25 dB step size using an 8-bit binary TTL control and has a switching speed of less than 800 ns. The attenuator can handle a CW input power up to 30 dBm, has an insertion loss of less than 5 dB and a VSWR of under 2:1. It consumes up to 150 mA of current while operating over a supply voltage from +12 to +15 V and consumes up to 75 mA of current while operating over a supply voltage from -12 to -15 V. The attenuator is available in a module that measures 2.00 x 1.80 x 0.50 inches with SMA-female connectors.
