Relay controlled attenuators cover broadband frequencies from dc to 2000MHz
FAIRVIEW MICROWAVE Line of relay controlled programmable attenuators provide accurate and stable performance with very low harmonic distortion (IMD) and cover multiple RF frequency bands down to dc. Devices are suitable for use in military and commercial satellite and ground communication systems, cable modem and cellular telephone testing, radar, telecommunications and automatic test equipment (ATE). Product line consists of six models that cover broad frequency bands from dc to 2000 MHz with attenuation levels ranging from 0 to 127dB. Device designs have 6 to 8 relay bits with attenuation steps ranging from 0.25dB to 64dB for precise tuning capability, depending on the model. Typical performance includes low insertion loss ranging from 0.8 to 3.5 dB, input power up to 1-watt CW and attenuation accuracy of +/- 0.5 dB. Models are offered in 50 and 75 Ohm configurations and feature bidirectional performance capability for added convenience.
