Fairview Microwave Inc. has introduced a line of relay controlled programmable attenuators that offer accurate and stable performance with very low harmonic distortion (IMD) and cover multiple RF frequency bands down to DC.
They are popular for use in military and commercial satellite and ground communication systems, cable modem and cellular telephone testing, radar, telecommunications and automatic test equipment (ATE).
Typical applications include signal conditioning and level control, matching impedances of sources and loads and measuring the gain or loss of two-port devices.
