Abstract

This paper presents a SiGe BiCMOS transmitter for large bandwidth Polar Modulation and PWM signals. For flexibility, the transmitter presented in the paper has an externally controllable class of operation. Fabricated in a SiGe BiCMOS process (QUBIC4G), the measured saturated output power of the transmitter is 27dBm and the measured PAE is 62%. It features an IMD3 of -30dBc up to 25dBm peak envelope power and fulfills the spectral mask for WLAN 802.11.a signals.
