In [1] a fully-digital polar modulator is presented, which enables a SAW-less 2G/3G transmitter, in particular by solving the transmitter (TX) noise in receive (RX) band issues at various duplex distances (45/80/190/400MHz). Removing the TX SAW filter by adopting innovative transmitter topologies not only reduced the amount of external
