Pasternack Enterprises has announced a new line of tunable band pass filters and band reject filters. Also known as band-stop filters or band-rejection filters, the new devices are bench top units which have been designed for lab use where they are an integral part of the test lab environment.

Featuring a tunable 5-section design and a mechanical direct dial that is accurate within 1%, there are six bandpass configurations available with octave-band tuning from 125 MHz to 3 GHz and a 5% pass band. The band reject filters are accurate to 1% of the reject band, utilize a 3-section design and are available in five bandreject configurations with octave-band tuning ranges from 100 MHz to 2 GHz. Designed with Type N female connectors, the bandpass and bandreject filters both feature an average power handling of 50 Watts.

Gerry Camacho, VP of Technical Marketing at Pasternack Enterprises, comments: “Tunable filters are an essential component in any test lab focused on designing and building RF and wireless systems. Our new tunable bandpass and bandreject filters are an ideal solution for our customers’ increased demand for test and measurement products.”

Capable of attaining high attenuation of greater than 50 dB, Pasternack’s tunable RF filters are perfect for a lab environment testing UHF, PMR, Tetra, LTE, PCS and WiFi frequency bands. Effective in band selection or frequency discrimination, the tunable filters are highly durable employing a ruggedized aluminum construction with silver plated critical surfaces.

Pasternack’s tunable band pass filters and band reject filters offer excellent noise, harmonic and adjacent-band reduction.
