6.3 Feature Description

Besides the PA, LNA, and the ANT switch, the TRF2001P integrates additional functions such as a harmonic rejection filter and a power detector in a small 4.5mm × 4.5mm package.

The integrated harmonic rejection filter either eliminates the need for an external filter to the antenna or notably relaxes the rejection requirements of the external filter if the system requires one. The TRF2001P inherently achieves second order harmonic rejection below –55dBc at PO = 27dBm without any external filtering. The integrated power detector provides analog voltage output corresponding to the output power as shown in Figure 5-6 and has a very stable response across temperature and supply voltage.
