Fairview Microwave, Inc., a supplier of microwave and RF products, has introduced new lines of band-pass and band-reject tunable filters.
Suitable for testing frequency bands including PCS, UHF, PMR, Tetra, LTE, and Wi-Fi in laboratory environments, Fairview Microwave’s new tunable band-pass filters and band-reject filters, also known as band-stop filters or band-rejection filters, are effective in band selection or frequency discrimination with high attenuation greater than 50 dB possible.
This latest release includes six band-pass filters capable of octave-band tuning from 125 MHz to 3 GHz depending on configuration, and a 5% pass band. They employ a 5-section tunable design and have a mechanical dial accurate within 1%. Also available are five band-reject models with octave-band tuning ranges from 100 MHz to 2 GHz depending on configuration, and a 1% reject band. These band-reject filters use a 3-section design and have a mechanical dial tuner accurate to 0.5%.
The new filters are rated to 50 Watts CW power handling and are designed with N female connectors and ruggedized aluminum casings with silver plating for extra durability.
“Tunable filters are frequently used by RF design engineers in EMC/wireless test environments to ensure their systems are operating properly in a crowded RF/microwave spectrum environment. These filters provide a handy solution for pre-tuning desired signals and rejecting unwanted interference,” Greg Arnold, technical sales manager at Fairview Microwave, said.
