Controlled Programmable Attenuators Offer Precision Stepped Attenuation Levels
up to 127 dB
Calif. - Fairview Microwave Inc., an Infinite Electronics brand and a
leading provider of on-demand RF and microwave components, has introduced a new 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.
Fairview’s new line
controlled programmable attenuators
consists of six models that
cover broad frequency bands from DC to 2000 MHz with attenuation levels ranging
from 0 to 127 dB. These attenuator designs have 6 to 8 relay bits with
attenuation steps ranging from 0.25 dB to 64 dB 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.
“This line of relay controlled programmable attenuators gives
designers a complete selection of accurately controlled attenuation step sizes
needed for signal conditioning and testing applications. For additional accessibility,
all models are in stock and ready to ship,” said Tim Galla, Product Manager.
These attenuator assemblies are available in rugged, nickel-plated
brass packages with either female F-type or SMA 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 models have an operational temperature range of -20°C to +85°C,
are RoHS compliant and export-rated as EAR99.
Fairview Microwave’s new relay controlled programmable attenuators
are in stock and ready for immediate shipment with no minimum order quantity.
