Relay Controlled Programmable Attenuator Series

Pasternack’s relay controlled programmable attenuator series cover broad frequency bands from DC to 2000 MHz with attenuation levels ranging from 0 to 127 dB. Depending on the model, these programmable attenuator designs have 6 to 8 relay bits with attenuation steps ranging from 0.25 dB to 64 dB for precise tuning capability.

Typical attenuator performance includes low insertion loss ranging from 0.8 to 3.5 dB, attenuation accuracy of +/- 0.5 dB and input power up to 1-watt CW. For added convenience, relay control programmable attenuator models are offered in 50 and 75 Ohm configurations. These Pasternack attenuators with relay control feature bidirectional performance capability.

These attenuator components are RoHS compliant and available in rugged nickel-plated brass packages with either female SMA or F-type connectors. Each relay bit has a designated RFI pin with a DC bias of +12 Vdc and 15 to 30 mA depending on the model. All programmable attenuator models are export-rated as EAR99 and have an operational temperature range of -20°C to +85°C.
