Precision Electrical Performance

Our 1709.5-1784.5MHz/1804.5-1879.5MHzCavity Diplexerstores and releases energy in quarter-wave coaxial cavities, creating a 75 MHz split that keeps transmit and receive paths electrically separate. Each Cavity Diplexer is tuned on a 20 GHz VNA to guarantee insertion loss ≤1.0 dB and TX/RX rejection ≥60 dB, ensuring your base-station, repeater or DAS head-end runs without self-quieting.

Factory Backbone – Why Keenlion

• 20-year Chengdu plant machines, plates, tunes and tests every Cavity Diplexer under one roof • 7-day prototype lead, 21-day volume schedule • Insertion loss, isolation and VSWR verified on signed VNA plot • Competitive factory prices with no distributor margin • Free samples shipped in 48 hours • Professional after-sales support for life of the Cavity Diplexer
