SLOS757G December 2011 – March 2020 TRF7962A
Figure 7-1 shows the TRF7962A application schematic using the serial port interface (SPI). Short SPI lines, proper isolation to radio frequency lines, and a proper ground area are essential to avoid interference. The recommended clock frequency on the DATA_CLK line is 2 MHz.
This schematic shows matching to a 50-Ω port, which allows connection to a properly matched 50-Ω antenna circuit or RF measurement equipment (for example, a spectrum analyzer or power meter).
