The DAT-14-482/1S from Pulsar Microwave is a Digitally Controlled Attenuator that operates from 4 to 8 GHz. This 8-bit attenuator provides an attenuation of up to 32 dB with an LSB of 0.125 dB and has a switching speed of 600 ns. It has an insertion loss of less than 5.5 dB and a VSWR of under 2:1. This attenuator can handle up to 27 dBm of average/peak power. It operates over a DC supply voltage from 12 to 15 V and consumes up to 100 mA of current.
This attenuator can be controlled by an 8 Bit TTL driver. It is available in a module that measures 3 x 2.35 x 1 Inches with SMA (F) connectors.
