SLW7409B Transceiver for 5.5G/6G/LEO Application 

SLW7409B is a CMOS silicon on insulator (SOI), 24GHz to 44GHz, mmWave 5.5G/6G SATCOM beamformer. The SLW7409B drives 8 horizontal and 8 vertical polarized antennas via independent RFV and RFH bond pads. In transmit mode, the RFT and RFB input pins drive the 16 independent transmit channels via the 1:8 power splitters. The transmit channels feed the 16 RFV/RFH antenna ports. In receive mode, input signals pass through the 16 receive channels and combine via two independent 8:1 power combiners to the common RFT pin or RFB pin. In either mode, each transmit and receive channel includes a phase shifter (PS) to control the phase, and variable gain amplifiers (VGAs) to control the amplitude. The phase shifter has a full 360° phase adjustment range in either transmit or receive mode, with 10 bits of resolution. The RFV and RFH bond pads can be connected directly to a 5.5G/6G SATCOM mmWave antenna array. The SLW7409B can be programmed using a 3-wire serial port interface (SPI). Various SPI modes are available to enable fast startup and control during normal operation. The amplitude and phase for each channel can be set individually or multi- channels can be programmed simultaneously using the on-chip SPI for beamforming.
