Duplexer (8)
RF Cavity Duplexers for Radio Repeater Systems
VGC designs, engineers, and manufactures heavy-duty RF cavity duplexers tailored for global B2B procurement, telecommunications deployment, and wireless networks. From ultra-compact 10W vehicular modules to 100W national base station backbone infrastructure, our duplexers deliver flawless single-antenna Tx/Rx isolation.
Elite Skirt Selectivity
Engineered with premium silver-plated copper loops and high-Q resonant cavities to provide superior rejection bounds (≥75dB / ≥80dB), eliminating co-site receiver desensitization.
Zero Thermal Drift
Utilizing internal Invar temperature compensation tuning rods, ensuring your radio repeaters remain perfectly locked to their center frequencies across severe ambient environments (-30°C to +60°C).
B2B Custom Tuning
Every single batch is custom-tuned to your precise TX/RX frequencies, passband configurations, splits, and connector types (N-Female / BNC) by our expert vector network analyzer laboratory before shipment.
