- 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. Internal fractional nPLL allows support for a wide range of reference clock frequencies

- WIFI Transmission Baseband data is modulated and upconverted to the 2.4GHz ISM band, respectively. Base-band Processing (BBP) IC has DSSS and OFDM modulation function, it provides transmission data rate are 1, 2, 5.5, 11Mbps 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.

- WIFI 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.

- Antenna Integral metal antenna is used. Detail antenna gains are listed in the FCC/ISED test reports. Version 1.0 Samsung Electronics page 2 of 6
