5.4 Power Amplifier

A highly efficient single-ended Power Amplifier (PA) is integrated in the RFM119W/RFM119SW to transmit the modulated

signal out. Depending on the application, the user can design a matching network for the PA to exhibit optimum efficiency at

the desired output power for a wide range of antennas, such as loop or monopole antenna. Typical application schematics

and the required BOM are shown in “Chapter 4 Typical Application Schematic”. For the schematic, layout guideline and the

other detailed information please refer to “AN101 CMT211xA Schematic and PCB Layout Design Guideline”.

The output power of the PA can be configured by the user within the range from -10 dBm to +13 dBm in 1 dB step size using

the HOPERF USB Programmer and RFPDK.
