RF Filters

MIL-E-5400 standard | Low & High pass Filters | Tuneable band reject Filter

Filters are (functionally) fairly simpler devices. There are a number of different types but their names indicate the kind of filter:
- Low pass (lets the lower frequencies through the filter)
- High Pass (lets the higher frequencies through the filter)
- Band pass (lets a band of frequencies pass through the filter)
- Band reject (does not let a band of frequencies pass through the filter)
- Diplexer (separates two bands)

Pasternack RF filters are passive coaxial components available in three basic varieties: Lowpass, High pass and Bandpass. 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 WiFi, Bluetooth, Zigbee, GPS L1, GPS L2, GSM, PCS, UMTS, AWS and WIMAX.

Pasternack

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. Pasternack's Bandpass filters, Lowpass filters and Highpass filters have very low insertion loss from 0.75 dB to 1.5 dB.
