6.11 Transmitter – External Power Amplifier or Subcarrier Detector

The TRF7963A can be used in conjunction with an external TX power amplifier or external subcarrier detector for the receiver path. If this is the case, Bit B6 of the Regulator and I/O Control register (0x0B) must be set to 1. This setting has two functions: First, to provide a modulated signal for the transmitter, if needed. Second, to configure the TRF7963A receiver inputs for an external demodulated subcarrier input. The design of an external power amplifier requires detailed RF knowledge. There are also readily designed and certified high-power HF reader modules on the market.
