MCV Microwave cavity filters are available from 10 MHz to 40 GHz and with bandwidth from 0.1% to over 66%. Cavity filters offer very high Q and low insertion loss, steep skirt selectivity, and narrower bandwidths. MCV combline cavity and waveguide filters include cavity band pass filters, cavity band reject filters, cavity multiplexers, dual cavity duplexers, combline band pass filters, interdigital filters, waveguide bandpass filters and dielectric resonator loaded cavity filters.
