Overview. NXP's RapidRF front-end designs for 5G infrastructure integrate a linear pre-driver, RF power amplifier, Rx LNA with T/R switch, a circulator and a bias controller in a compact footprint. They incorporate a coupler for DPD feedback and are to be used with digital pre-distortion.

Figure 3: Sub-Level Block Diagram Block 1: RF Front End A RF signal is input into the RF front end as shown in Figure 4. In lab, a signal generator produces the RF signal, but in application, an antenna would be used to receive the signal. The signal is amplified in a low-noise amplifier (LNA) to increase the power of the input signal.

The RF front end contains a number of components that work together to ensure signal integrity throughout the signal's bandwidth. This includes preparing a signal for transmission, as well as receiving and demodulating a signal received on the Rx side. The functional block diagram below shows the general topology of an RF front end.
