DESCRIPTION
The CX72303 is the lowest powered, fully integrated single-
chip Bluetooth radio transceiver. Fully compliant with
Bluetooth Specification v1.1, the CX72303 was designed from
the ground up for extreme low power operation in handsets,
headsets, or other power sensitive applications. Extreme low
power 1.8 V operation is combined with high performance to
exceed the Bluetooth requirements for Class 2 and 3 operation.
The CX72303 has an internal voltage regulator that allows
operation with higher supply voltages while holding the line on
power consumption. An extended frequency range is provided
to allow operation in all 2.4 GHz Industrial, Scientific, and
Medical (ISM) band regulatory jurisdictions. Transmitter output
power is up to +3 dBm with a typical receiver sensitivity of
–82 dBm at the antenna.
Fabricated in a Silicon-Germanium (SiGe) Bi-polar
Complementary Metal Oxide Semiconductor (BiCMOS) process,
the CX72303 is a state-of-the-art mixed signal device mounted
in a small, low profile 7 x 7 x 0.8 mm Bump Chip Carrier
(BCC++) 48-pin package.
A block diagram of the CX72303 is shown in Figure 1.
