Precise Electrical Response
Our 1920-1980MHz / 2110-2170MHz Cavity Diplexer uses quarter-wave coaxial cavities tuned to 1950 MHz (Rx) and 2140 MHz (Tx). Each Cavity Diplexer is swept on a 20 GHz VNA to guarantee insertion loss ≤1 dB and VSWR ≤1.3:1 on both paths, while rejection ≥60 dB across the opposite band ensures the Cavity Diplexer eliminates Rx/Tx self-quieting in LTE-FDD, 5G-NR or private-network radios.
Rugged Mechanical Build
The 1920-1980MHz / 2110-2170MHz Cavity Diplexer is milled from one-piece aluminium, black-paint finished and stable performance from -20 °C to +65 °C. SMA-F connectors are torque-sealed; the Cavity Diplexer can be wall-mounted with two M3 holes or supplied with custom brackets.
