The PT8R1002 is a part of the PTI Bluetooth product
family. It is a short-range microwave-frequency radio
transceiver for Bluetooth links that operates in the
2.4 GHz to 2.5 GHz ISM band. The device consists
of a fully integrated 2.4 GHz radio transceiver with
GFSK modem. This radio IC is based on PTI’s
proprietary radio architecture employing direct
conversion scheme, which offers superior channel
selectivity, and is implemented in CMOS technology,
which provides low cost integrated RF and baseband
solutions for Bluetooth applications.
The PT8R1002 incorporates the complete receive and
transmit components including PLL, VCO, LNA, up/
down converter, channel select filters, and digital
GFSK modem.
