SLW7308B Transceiver for 5.5G/6G Satcom Application 

SLW7308B is a CMOS silicon on insulator (SOI), 24GHz to 44GHz, mmWave 5.5G/6G Satcom beamformer. The SLW7308 drives 4 horizontal and 4 vertical polarized antennas via independent RFV and RFH bond pads.
In transmit mode, the RFT and RFB input pins drive the eight independent transmit channels via the 1:4 power splitters. The transmit channels feed the 8 RFV/RFH antenna ports. In receive mode, input signals pass through the 8 receive channels and combine via two independent 4:1 power combiner to the common RFT pin or RFB pin. In either mode, each transmit and receive channel includes a phase shifter (PS) and variable gain amplifiers (VGAs) to control the phase and amplitude. The phase shifter has a full 3600 phase adjustment range in either transmit or receive mode, with 5 bits of resolution (expandable to 9-bit resolution).
The RFV and RFH bond pads can be connected directly to a 5.5G/6G Satcom mm-Wave antenna array. The SLW7308 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 programmed either individually or multiple channels simultaneously using the on-chip SPI for beamforming.
