RF Filters

Pasternack RF filters are passive coaxial components available in three basic varieties: Bandpass, Lowpass and Highpass. The basic function of these RF filters is to allow for certain frequencies to pass within a certain range and rejecting frequencies (attenuation) outside that given range. RF filters from Pasternack are available for use in many common frequency bands including ISM, RFID, WiFi, Bluetooth, Zigbee, GPS L1, GPS L2, GSM, PCS, UMTS, AWS and WIMAX. Many of our RF filters are RoHS and REACH compliant.


Pasternack’s RF filters come with SMA connectors and have a broad range of frequency capabilities from DC to 5.9 GHz depending on type and style. Our Bandpass filters, Lowpass filters and Highpass filters have very low insertion loss from 0.75 dB to 1.5 dB. These RF filters are constructed using the Combline design which provides outstanding VSWR and long term performance.


The ISO 9001:2008 registered Pasternack facility ships all RF filters from stock the same day you order them.
