to 723 kbps.
• Personal Digital Assistants
The radio employs an integrated antenna filter and

switch to minimize the number of external
components.
• Automotive Telematics
The radio has a heterodyne receiver architecture with
a low intermediate frequency (IF), which enables the
IF filters to be integrated on-chip. The transmitter
uses direct IQ-modulation with Gaussian-filtered bit-
stream data, a voltage-controlled oscillator (VCO)
buffer, and a power amplifier.
