Scientific Microwave Corporation (SMC) has introduced the WR90 high-power 4-port differential phase shifter (duplexer), which is an advanced RF device designed for applications where precise phase control, high-power handling, and thermal management are crucial. The combination of phase shifting and isolation allows it to operate efficiently under high-power conditions often seen in industrial, scientific, as well as in advanced communication and radar systems. It is the preferred choice for applications that demand enhanced signal strength and optimal efficiency within the specified frequency range from 9.20 to 10.20 GHz.
The primary function of a differential phase shifter is to control the signal phase in a precise and dynamic manner to achieve beamforming or signal steering. In general, for a differential phase shifter, the transmitter (TX) is connected to port 1, while the antenna is connected to port 2. The antenna, upon receiving the signal, sends the signal to the receiver (RX), while port 4 is terminated with a high-power matched load.
Isolation Performance vs. Frequency
This 4-Port WR90 differential phase shifter stands out with its impressive matching level, high isolation, and minimal insertion loss with high-power handling capability. It provides an isolation of 20 dB and has an insertion loss of 0.4 dB. This differential phase shifter can handle an average input power of 800 W (CW) and a peak input power of 20 kW with a VSWR of 1.20:1.
This waveguide duplexer device is available in an Aluminum housing and has a rectangular cover with through holes at the input and output ports.
