The BGB101 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 balans, 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 impedance and
can be connected directly to an external antenna, with a
50 transmission line.
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 and
13. 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
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 SOT750A package with a
plastic cap.
The interfacing to the baseband processor is very simple,
This device is sensitive to electrostatic discharge (ESD). Therefore care should be taken during transport and handling.
