IRVINE, Calif. – Pasternack Enterprises Inc. in Irvine, Calif., is introducing a series of RF and microwave relay-controlled programmable attenuators for military and commercial satellite and ground communication systems, cable modem and cellular telephone testing, radar, telecommunications, and automatic test equipment (ATE).
Relay-controlled programmable attenuators offer accurate and stable performance with very low harmonic distortion, and cover several RF frequency bands down to DC.
They are for signal conditioning and level control, matching impedances of sources and loads, and measuring the gain or loss of two-port devices.
Pasternack's six new models of relay-controlled programmable attenuators cover frequency bands from DC to 2000 MHz with attenuation levels ranging from 0 to 127 dB. Attenuator designs have six to eight relay bits with attenuation steps ranging from 0.25 dB to 64 dB for precise tuning capability.

Typical performance includes insertion loss ranging from 0.8 to 3.5 dB, attenuation accuracy of +/- 0.5 dB and input power to 1-Watt CW. For added convenience, models are offered in 50 and 75 Ohm configurations and feature bidirectional performance capability.
These attenuator assemblies 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 volts DC and 15 to 30 milliamps depending on the model. All models are export-rated as EAR99 and have an operational temperature range of -20 to 85 degrees Celsius.
