200MHz-40GHz Quadruplexer / High power capacity, low loss, miniaturisation, integration
product description
As one of the important components in microwave devices, Quadruplexers are usually used to simultaneously process four signal channels of different frequencies for signal separation, merging or switching.
Our quadruplexers have excellent performance characteristics such as frequency selectivity, low insertion loss, high return loss, and high power capacity to ensure precise control of the signal path by the quadruplexer. Our quadruplexers are also miniaturised and integrated. Miniaturised quadruplexers are easy to install and use in limited spaces, while integrated quadruplexers enable the integration of more functions and simplify system design.
