Tunable Band Pass and Band Reject Filters

Pasternack tunable band pass filters and band reject filters (also referred to as band-stop filters or band-rejection filters) are bench top units designed for lab use where they are an integral part of the test lab environment. Six adjustable bandpass filter configurations are available with octave-band tuning from 125 MHz to 3 GHz and a 5% pass band. These variable band pass filters use a tunable 5-section design and have a mechanical direct dial that is accurate within 1%.

Five tunable bandreject configurations are available with octave-band tuning ranges from 100 MHz to 2 GHz and are accurate to 1% of the reject band. Pasternack variable band reject filters utilize a 3-section design and have a mechanical direct-dial tuner accurate to 0.5%. Both the adjustable bandpass and bandreject notch filters have an average power handling of 50 Watts and are designed with Type N female connectors.

Pasternack’s tunable RF filters are perfect for a lab environment testing UHF, PMR, Tetra, LTE, PCS and WiFi frequency bands. The tunable radio frequency filters are effective in band selection or frequency discrimination with high attenuation greater than 50 dB possible, allowing for excellent noise, harmonic and adjacent-band reduction. These highly durable adjustable bandpass filter and band reject filter units employ ruggedized aluminum construction with critical surfaces being silver plated.
