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 diplexer model has been designed for applications that require a high level of TX-RX isolation. It has a temperature range of -20 to +85°C and a maximum VSWR of 1.5:1.
The MtronPTI LF9422 L/S Band LC Filter Diplexer is custom designed for small form factor UAV-ISR platforms. Unlike open frame designs, the 1” x 1” wash-proof surface mount package is sealed, allowing automated assembly with no drift after board cleaning.
The QPQ6108 by Qorvo is a high-performance, temperature-compensated Surface Acoustic Wave (TC-SAW) duplexer. This product is designed for Band 8 uplink/ downlink applications.
