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.

Typically, an internal antenna may be custom designed and integrated into a radio’s printed wiring board (PWB) or case and implemented as a separate component. Matching elements are then attached to the PWB or remotely connected to the radio with a cable and connectors. These alternatives suffer from inflexibility and poor economy. A new hexaband cellular antenna that is partly integrated into the PWB and compatible with mass production has been designed and tested. The new design offers the benefits of customization and high volume production without requiring a separate matching network.

MCV Microwave was founded based on expertise in the area of high Q / low loss dielectric ceramic and microelectronic material and manufacturing technology. Over the past twenty years, we have accumulated RF/Microwave and EM design experience led by industry gurus in various filter topologies including ceramic, lumped element, combline cavity and waveguide. Focusing on patent pending broadband antennas for IoT and high performance filter products, we are positioned to bring connectivity to serve the 5G next generation of wireless.

The widespread use of ceramic dielectric resonators in place of metallic resonant cavities in RF and microwave circuits started in the 1970s, with the first low loss, temperature stable barium tetratitanate ceramic materials.1 Further development of high dielectric constant ceramics with adjustable temperature coefficients enabled microwave engineers to use these materials in oscillator and narrowband filter designs for radar detectors, cellular phone and public safety base stations, satellite receivers and satellite broadcasting (TVRO/DBS) applications.
