Abstract
This paper describes a 3-band (mode 1) multi-
band-OFDM UWB synthesizer implemented in a 0.25-
m SiGe
BiCMOS process. The interference-robust, fast-hopping synthe-
sizer uses one single-sideband (SSB) mixer for frequency shifting.
A single phase-locked loop (PLL) generates the steady input
signals for the SSB-mixer. Crucial in the design is a divide-by-5
frequency divider that generates quadrature signals at a frequency
of 528 MHz. The 0.44 mm
/50fully integrated synthesizer consumes
52 mW from
