Version 1.1 Samsung Electronics page 2 of 53. Operational DescriptionSPW-B4339S is the 802.11a/b/g/n /ac +Bluetooth 4.1 COMBO Module that acts as a communication controller for users of a wireless device to connect to Printer - Features >IEEE 802.11ac compliant. >Dual-band 2.4GHz /5 GHz >Single-stream spatial multiplexing up to 433.3Mbps data rate >Support 20,40,80MHz channel with optional SGI(256QAM modulation) >On-chip power amplifiers and low–noise amplifiers for both bands. >Complies with Bluetooth Core Specification Version 4.0 >Bluetooth Class 1 or 2 transmitter operation. >Adaptive frequency hopping (AFH) for reducing radio frequency interference - Time base of the RF frequency For IF and RF frequency, a crystal(37.4MHz) 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 and 5-GHz U-NII bands,respectively. Linear on chip power amplifier are included, which are capable of delivering high output powers while Meeting IEEE802.11ac and IEEE802.a/b/g/n specifications without the need for external PAs. When using the internal PAs, closed-loop output power control is completely integrated. Base-band Processing (BBP) IC has DSSS (BPSK/QPSK/CCK) and OFDM (BPSK/QPSK/16QAM/64QAM/25QAM) 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 The BCM43569 has a wide dynamic range, direct conversion receiver that employs high-order on-chip channel filtering to ensure reliable operation in the noisy 2.4GHz ISM band or the entire 5GHz U-NII band .Control signals are available that can support the use of optional LNAs for each band,which can increase the receive sensitivity by several decibels. 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.
