UFDX9999-002 C-Band Cavity Diplexer

UFDX9999-002 C-Band Cavity Diplexer/Splitter Assembly

Mtron, a leader in reliable, mission-critical space filters has introduced the UFDX9999-002, a C-band Diplexer/Splitter Assembly that supports satellite applications such as the Golden Dome. An integrated diplexer/splitter enables a 25% reduction of the board space required. The Assembly incorporates highly selective bandpass filters and a splitter for full-duplex data transmission with low loss and outstanding isolation between the uplink and downlink bands. With a commitment to advancing defense capabilities, Mtron offers one of the industry’s most comprehensive selection of RF filters.

The passbands, temperature range, and power handling can be customized for each application. The diplexer is compact, lightweight, and offers constant VSWR over temperature across bands. Mtron’s products support rugged, high-performance communication links that require full-duplex operation in airborne, land, maritime and deep space applications.

Mtron offers a broad line of precision crystal resonators, oscillators, filters, and RF Solutions. Mtron is an ISO 9001:2015 and AS9100 Rev. D certified organization.
