It is mounted in the refrigerator communication controller for using a wireless device user
The Bluetooth devices that act.
Channel based on the 802.15.1 / 1a of the Bluetooth standard IEEE 79 channels and frequency
Use the 2402MHz ~ 2480MHz band and channel interval is 1 MHz.

- Time base of the RF frequency
ZERO IF intermediate frequency using the method and the reference frequency is 26MHz crystal
without Use the Clock.

- Synthesizer
Transceiver size is relatively fresh inside the internal voltage controlled oscillator (VCO) and the PLL
system To respond to a wide adjustment range.

- Transmission
Baseband processing FHSS (frequency hopping spread spectrum run) and (GFSK / DQPSK /
8DPSK) modulation,
Data transfer speed is 1Mbps, 2Mbps (EDR), it will have a 3Mbps (EDR).
It handles the digital data signal to GFSK, 1MHz Data Rate
By the DAC in the BBP IC TX IQ signal is input through the modulation process and a TX carrier
frequency
The amplifier stage shelter will be sent.

- Reception
This transceiver IC is isolated to prevent unwanted noisy radiation by internal amplifier noise LOW
month
And the RF signal is through the intermediate frequency conversion and demodulation, and a RX IQ
signal via a low-pass filter
The input to baseband Processing.
