Bluetooth Radio Module - Nxp SemiconductorsThe BGB110 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 improved 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 AFC circuit compensates for VCO
drift and RF frequency errors during open-loop
demodulation.
The circuit is integrated on a ceramic substrate. It is
connected to the main PCB through a LGA (Land Grid
Array). A metal cap suppresses the effects of EMI (Electro
Magnetic Interference). The RF port has a normalized
50 impedance and CAN be connected directly to an
external Antenna with a 50 transmission line. By NXP Semiconductors
