General Descriptions

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.
