Varian VJW6767D8 Remote Control Unit Satellite Station PA Monitor RCA

Varian VJW6767D8 Remote Control Unit Satellite Station PA Monitor RCA

The Varian VJW6767D8 is a rackmount Remote Control Unit built by Varian's Microwave Equipment Division in Santa Clara, California for use in satellite ground station installations. It provides dual-section power amplifier monitoring and control — PA 1 and PA 2 — each with its own bank of indicator and alarm buttons and an analog output power meter. An RCA panel integration label is visible on the front, indicating this unit was configured for RCA satellite station infrastructure. The part number on the rear label is 112780-00, and the unit carries a Varian MED Inspected and Accepted by ERMA QA sticker.

Applications

Remote control units of this type were used in satellite earth station uplink facilities to monitor and switch between redundant high-power amplifiers (HPAs) — typically traveling wave tube amplifiers (TWTAs) or klystrons — used to drive the uplink signal to geostationary satellites. The dual-PA layout (PA 1 / PA 2) reflects a standard 1:1 redundancy configuration common in broadcast and telecom satellite ground stations of the 1970s and 1980s, where automatic or manual switchover to a backup amplifier was essential for maintaining continuous uplink service. The RCA branding visible on the front panel suggests this unit was built into or for an RCA satellite facility — RCA operated a major domestic satellite network (Satcom series) during this era. Varian's Microwave Equipment Division was a leading supplier of microwave and satellite amplifier systems to broadcast networks, government, and telecom operators during this period. This type of equipment is most relevant today to collectors, restorers of legacy satellite ground station systems, and engineers sourcing parts for vintage satcom infrastructure.
