Bluetooth Radio Module - Nxp Semiconductors

The 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
