Bluetooth Single-Chip Transceiver IC
Description
The T2901 is a bipolar intergrated circuit manufactured
using TEMIC Semiconductors’ advanced UHF process.
This IC includes a transceiver for the 2.45 GHz ISM band
especially for Bluetooth applications.
Features
Complete Bluetooth transceiver with fully integrated
synthesizer and VCO
TX with advanced closed-loop modulation
TX PA with +3 dBm output power at 2.5 GHz and
ramp-signal generator for optional front end
Image rejection mixer
Auxiliary voltage regulator on chip
Supply-voltage range 2.7 V to 3.3 V
(6 V with additional external PNP transistor )
Few low-cost external components /
No mechanical tuning required
