Miteq U-9456 54735 Ku-Band Upconverter 70 MHz IF 13.5-14.5 GHz RF Satcom

The Miteq U-9456/54735 is a Ku-Band upconverter designed for satellite communications earth station applications. It accepts a 70 MHz intermediate frequency (IF) input signal and converts it to an RF output in the 13.5–14.5 GHz Ku-Band range for transmission via satellite. The unit features front-panel LCD readout of RF frequency, attenuation, modulation, modulation rate, and deviation, along with a full numeric keypad and function key section for local setup and control.

Applications

Ku-Band upconverters like the Miteq U-9456 are a core component in satellite earth station transmit chains. They sit between the baseband/modem equipment and the high-power amplifier (HPA), translating the modulated IF signal — typically at 70 MHz or 140 MHz — up to the Ku-Band transmit frequency for the antenna system. The 13.5–14.5 GHz output range covers the standard Ku-Band uplink allocation used by commercial VSAT networks, broadcast contribution links, and government/military satcom terminals. Miteq has been a long-established manufacturer of satellite and microwave frequency conversion equipment, and the U-series upconverters were widely deployed in fixed and transportable earth stations from the 1990s onward. Units like this are still actively used in legacy earth station systems, teleport facilities, and as spare/replacement equipment in satcom networks that rely on 70 MHz IF architecture. The front-panel numeric keypad and LCD display allow standalone local operation, while the dual remote interface ports support integration into automated antenna control or redundancy switching systems.
