136-174 MHz /450-512MHz RF Diplexer (SMB Female, IP60)
RF duplexer is an electronic device that allows bi-directional (duplex) communication over a single path. In radar and radio communications systems, it isolates the receiver from the transmitter while permitting them to share a common antenna. Most radio repeater systems include a duplexer. Duplexers can be based on frequency polarization, or timing.
A Duplexer is a 3-port device that allows the transmitter and receiver to use a single antenna, while operating at the same/similar frequencies. Topwave model TPW-DP-1350-SMBF, a 136-174/450-512MHz RF duplexer with SMB female connector. The parameter PIM can avoid mutual signals interference effectively when different channel signals. The units work well with Low VSWR, low insertion loss and high isolation.
