DESCRIPTION
The BGB100 TrueBlue Bluetooth radio module is a
short-range radio transceiver for wireless links operating in
the globally available ISM band, between 2402 and
2480 MHz. It is composed of a fully integrated,
state-of-the-art near-zero-IF transceiver chip, an antenna
filter for out-of-band blocking performance, a TX/RX
switch, TX and RX baluns, the VCO resonator and a basic
amount of supply decoupling. The device is a “Plug-and
Play” module that needs no external components for
proper operation. Robust design allows for untrimmed
components, giving a cost-optimized solution.
Demodulation is done in open-loop mode to reduce the
effects of reference frequency breakthrough on reception
quality. An advanced offset compensation circuit
compensates for VCO drift and RF frequency errors during
open-loop demodulation, under control by the baseband
processor.
The circuit is integrated on a ceramic substrate. It is
connected to the main PCB through a LGA (Land Grid
Array). The RF port has a normalized 50 Ω impedance and
can be connected directly to an external antenna, with a
50 Ω transmission line.
The interfacing to the baseband processor is very simple,
which leads to a low-power solution. Control of the module
operating mode is done through a 3-wire serial bus and
one additional control signal.
TX and RX data I/O lines are analogue-mode interfaces.
A high-dynamic range RSSI output allows
near-instantaneous assessment of radio link quality.
Frequency selection is done internally by a conventional
synthesizer. It is controlled by the same serial 3-wire bus.
The synthesizer accepts reference frequencies of 12, 13,
16 and 26 MHz. This reference frequency should be
supplied by an external source. This can be a dedicated
(temperature compensated) crystal oscillator or be part of
the baseband controller.
The circuit is designed to operate from 3.0 V nominal
supplies. Separate ground connections are provided for
reduced parasitic coupling between different stages of the
circuit. There is a basic amount of RF supply decoupling
incorporated into the circuit.
The envelope is a leadless SOT649A package with a
plastic cap.
CAUTION
This product is supplied in anti-static packing to prevent damage caused by electrostatic discharge during transport
and handling. For further information, refer to Philips specs.: SNW-EQ-608, SNW-FQ-302A and SNW-FQ-302B.
