Abstract

This paper describes the design of an FSK transmitter for the 433 MHz ISM (Industrial, Scientific, Medical) band, which is realized in a standard digital 0.5 μm CMOS technology. It includes the PA itself, an upconverter, and the circuit generating the baseband quadrature signals with a continuous phase modulation. The overall measured efficiency of the packaged circuit is higher than 38% for a 1.2 V supply and an output power reaching 10 dBm at 433 MHz
