- Time base of the RF frequency

For IF and RF frequency, a crystal(40MHz) is a clock reference.

- Synthesizer

Synthesizer inside Transceiver. Internal voltage controlled oscillator (VCO) provides the desired LO
signal base on the phase-locked loop (PLL) with a relatively wide tuning range for this application.

- Transmission

Base-band Processing (BBP) IC has DSSS (BPSK/QPSK/CCK) and OFDM
(BPSK/QPSK/16QAM/64QAM) modulation function, it provides transmission data rate are 1, 2, 5.5, 11
Mbps on DSSS and 6, 12, 18, 24, 36, 48, 54 Mbps on OFDM. Digital data signal will be converted to
analog (TX IQ) signals through DAC in BBP IC, TX IQ pass through to low pass filter. TX I/Q signal
use direct conversion (zero-IF) architecture converter to generate carrier frequency signal. Transceiver
IC and internal PA magnify output power.

- Receiver

Reverse direction isolation of LNA inside Transceiver IC suppresses unwanted radiation. Then RF
signal will be directly down to IF signal (RX IQ) and high frequency spurious emissions are suppressed by
LPF. At last RX IQ signal will be demodulated digital data.

- Power Control Level

It uses open-loop power control function to limit RF output power level using a calibration file.

- Integrated Network Processor
Network processor manages Wi-Fi link operations. The network processor code is loaded automatically

from a ROM. The network processor is optimized for energy efficient communications
