The DTA-6380M7440M-60-9BDIFF-SFF from PlannarMonolithics Industries is a voltage variable attenuator that operates from 6380 MHz to 7440 MHz (to be switched at a 20 kHz rate over its specified frequency range). It has an insertion loss of 6.5 dB, a VSWR of 1.5:1 and power rating of 22 dBm CW. The attenuator comes with a control interface that allows for nine differential inputs to control the attenuator settings with an LSB of 0.25 dB and an attenuation range of 50 dB. It requires a supply of 15 VDC at 150 mA with reverse voltage protection and over-voltage protection to 30% of voltage rating.
