Product Profile
An RF duplexer is a device that allows bi-directional signal transmission over a single path. In radio or Radar communications systems, duplexers permit them to share a common antenna while isolating the receiver from the transmitter.RF and microwave Duplexer can be designed using lumped components or with micro-strips materials.Microstrip duplexers are designed in a similar way, a RF circulator is designed using the microstrip material. Various design topologies are available for the design and the specification of the duplexers are based on the following substrate specification used in the design.Duplexer help to connect one antenna to multiple radar systems to transmit and receive signals. This will help to reduce the cost and space needed for multiple large antennas for the multiple radars by sharing the antenna.Duplexer provides enough isolation between the transmitter and the receiver during the transmitting of the RF signals. The duplexer also avoids the reception of the reflected signal back to the transmitter. For the better protection of the receiver, PIN diode limiters are used in front of the receiver chain after the duplexer.
