UMT - Waveguide and Cavity Filters / Diplexers, Directional Couplers, Flat-Panel Antennas, Orthomode Transducers / Filters

Universal Microwave Technology, Inc (UMT) is a world leader in developing and manufacturing high-quality custom microwave / MM-wave passive components and flat-panel antennas for today’s wireless telecommunication market.

UMT’s products are designed and marketed exclusively for broadband wireless communications such as Point-to-Multipoint (PMP), Point-to-Point (PtP), LMDS, VSAT, ISM, WLL, and cellular base stations. Our range of products for antenna support includes filters, waveguide filters, diplexers, directional couplers, flat panel antennas, and all types of passive components up to 50GHz.

WAVEGUIDE FILTERS / DIPLEXERS UP TO 50GHZ

UMT is one of the leading manufacturers of waveguide filters and diplexers in the world. The company offers a complete line of waveguide filters and diplexers that have frequency range between 6GHz and 50GHz. The waveguide filters and diplexers are designed for wireless communication applications such as PTP, PMP, digital radios and base station links.

CAVITY FILTERS / DIPLEXERS FOR WIRELESS ACCESS

UMT manufactures a full range of cavity filters and diplexers for cellular base stations (GSM, PCS / PCN, ISM, UNII, WLL) and other wireless access applications such as WLAN and WiMax. The company offers cavity filters and diplexers, which are made in comblines filters or interdigital lines. The cavity filters and diplexers feature high attenuation and low insertion loss characteristics.

ORTHOMODE TRANSDUCERS / FILTERS

UMT supplies an extensive range of orthomode transducers / filters assembly for Ku-band and Ka-band Very Small Aperture Terminals (VSATs). The units are die-cast for higher volume production. The company also provides series of harmonic reject filters, which are used to suppress unwanted signal up to the third harmonics from the satellite transceivers.

UMT Orthomode Transducers (OMT) / filters are designed using corrugated low pass waveguide type or waffle iron type to provide high attenuation and wide stopband.

DIRECTIONAL COUPLERS

The company offers W/G directional couplers, which are employed in microwave point-to-point digital radio systems ranging from 6GHz to 40GHz. UMT also offers directional couplers, which are used in wireless applications such as cellular base stations.

CUSTOM FLAT PANEL ANTENNAS

UMT develops a range of custom design flat panel antennas providing fixed wireless access to standard ISM, WLL, UNII, and WLAN applications networks.

WAVEGUIDE AND COAXIAL ADAPTERS

UMT offers a series of off-the-shelf low cost waveguide to coaxial adapters ranging up to 50GHz.

POWER DIVIDERS

UMT offers compact size, low cost and high performance power splitters and combiners mostly used in the GSM, PCS / PCN base stations, WLL and other wireless applications.
