Diplexers and multiplexers are used to either separate or combine two different frequencies that are similar in range to one another. While bandpass filters can also be used to combine and separate signals, they’re only ideal for use with frequencies that are far apart from one another.
This cavity duplexer for WiMax applications features a small form factor, low insertion loss, high channel selectivity, high isolation, with both custom and standard designs available. Its low channel center frequency runs from 3400 to 3500 MHz, and its high channel center frequency runs from 3500 to 3600 MHz. This WiMax Duplexer’s operating temperature runs from -40 °C to +90 °C, has SMA female connectors, has 100 MHz channel separation, 40MHz channel bandwidth, 1.5 dB max passband insertion loss, and 16 dB min passband return loss.
