Coaxial Cavity Filters
These coaxial filters use cavity resonances to achieve high Q and thus low insertion loss, steep skirts and high isolation. JQL offers various categories of cavity filters. All standard designs can be modified easily and quickly to meet customer specific requirements.

Bandpass Cavity Filters
200 MHz to 15 GHz, SMA- or N-connectors, as drop-in or with horizontal pins.

Low Pass Cavity Filters
Band edge 450 MHz or 500 MHz

Coaxial Cavity Duplexers and Diplexers
For center frequencies from 100 MHz to 40 GHz

Coaxial Cavity Triplexers
With three internal bandpass filters, for the cellular frequency bands of GSM, UMTS and LTE

Coaxial Cavity Quadplexers
E.g. Quadplexer for EGSM900, UMTS2100, LTE800 and LTE2600

Cavity Multiplexers for 5 or 6 Cellular Frequency Bands

Cavity Filters for PIM Testing
Special high performance filters for test equipment which measures Passive InterModulation (PIM) distortion. At 2 x 20 W the PIM value is <-171 dBc.
