MCV Microwave offers high performance ultra-narrowband cavity filters and duplexers covering frequencies up to 13 GHz. Typically, cavity filters are known for low insertion loss, tight frequency selectivity and broad spectrum rejection. MCV Microwave’s dielectric loaded, cavity bandpass filters and duplexers — BCCD and DCCD series, respectively — bring these desirable performance characteristics to a new height for the microwave engineering community.

One example of the BCCD series is a 7.8 GHz cavity bandpass filter with only a 2 MHz 3 dB bandwidth (0.03% Fc) and 30 dB rejection 10 MHz from the center frequency on both sides. An example of a DCCD series is a 2 GHz with a 6 MHz split cavity duplexer that has a 3 MHz 3 dB bandwidth (0.1% Fc) with 60 dB rejection 1.5 MHz away from either band edge between the two passbands and 40 dB rejection 5.5 MHz away from the lower and higher band edges. These are offered in very compact packages: 2" × 1" × 0.5" for the BCCD cavity bandpass filter and 12" ´10" ´1.5" for the DCCD cavity duplexer.

In addition to cavity filters and duplexers, MCV offers dielectric resonators (DR) and DR loaded cavity filters for high power LTE and public safety base stations.

Vertically integrated, with in-house proprietary ultra-high Q dielectric resonators and 3D electromagnetic (EM) modeling, MCV Microwave designs and manufactures their ultra-narrowband filters and duplexers with precision and practicality. High Q and tight tolerance in both dielectric constant, εr, and temperature coefficient, Tf, are important characteristics in achieving RF/microwave system performance goals and maintaining stability over the operating temperature range.
