A3LWDG720MWi-Fi Transmitter Module

Manual For WDG720M SAMSUNG ELECTRONICS CO., Ltd. Wi-Fi module(2.4GHz, 5GHz, a/b/g/n) - Model name : WDG720M - Operation Temperature : -10°C ~ +70°C - Power : +5V ±5% (+4.75V ~ +5.25V) 1. Introduction WDG720M is a USB embedded module compliant with IEEE802.11n standard. Thecore chipset is from MTK, part number is RT3572L. 2. Operational Description WDG720M is the 802.11a/b/g/n RF Module, that acts as a communication hub for users of a wirelessdevice to connect to a wired LAN. MIMO type Product type: WLAN (11b mode: 1TX, 1RX, 11g mode: 1TX, 1RX, 11n mode: 2TX, 2RX) Time base of the transmission frequency For IF and RF frequency, Crystal is a clock reference. Synthesizer Synthesizer inside Transceiver. Internal voltage controlled oscillator (VCO) provides the desired LOsignal 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, 11Mbps on DSSS and 6, 12, 18, 24, 36, 48, 54 Mbps on OFDM. Digital data signal will be converted toanalog (TX IQ) signals through DAC in BBP IC, TX IQ pass through to low pass filter. TX I/Q signaluse direct conversion (zero-IF) architecture converter to generate carrier frequency signal. TransceiverIC and internal PA magnify output power. Receiver Reverse direction isolation of LNA inside Transceiver IC suppresses unwanted radiation. Then RFsignal will bedirectly down to IF signal (RX IQ) and high frequency spurious emissions are suppressed by LPF. Atlast RX IQ signal will be demodulated digital data. Base band Processing 1. Channel selection is controlled by BBP IC to support data modulation: - DSSS (BPSK/QPSK/CCK) - OFDM (BPSK/QPSK/16QAM/64QAM) Power Control Level It uses closed-loop power control function to limit RF output power level. Transmit/Receive Switch EUT has Transmit/Receive Switch and Antenna switch. End user can’t select any power setting. Channel Selection Restriction For product available in the USA/Canada/Taiwan market, only channel 1~11 can be operated. Selectionof other channels is not possible. But product also could be available in the Europe/Japan market,channel 1~13 can be operated under the manufacturer change the different driver. Data Rate Control The operation date rate is changing during data transfer base on the optimization of driver. Discontinue Transmitting with absence of Data or operational failure states “The device shall automatically discontinue transmission in case of either absence of information totransmit or operational failure. These provisions are not intended to preclude the transmission of controlor signaling information or the use of repetitive codes used by certain digital technologies to completeframe or burst intervals. Applicants shall include in their application for equipment authorization adescription of how this requirement is met.” Data transmission is always initiated by software, which isthen passed down through the MAC, through the digital and analog baseband, and finally to the RF chip. Several special packets (ACKs, CTS, PSPoll, etc...) are initiated by the MAC. These are the only waysthe digital baseband portion will turn on the RF transmitter, which it then turns off at the end of thepacket. Therefore, the transmitter will be on only while one of the aforementioned packets is beingtransmitted.

If the average output power procedure is used to measure the fundamental emission power to demonstrate compliance to 15.247(b)(3) requirements, then the power in any 100 kHz outside of the authorized frequency band shall be attenuated by at least 30 dB relative to the maximum measured inband average PSD level. In either case, attenuation to levels below the general emission limits specified in §15.209(a) is not required. ▣TEST CONFIGURATION ▣TEST PROCEDURE The transmitter output is connected to a spectrum analyzer. - Measurement Procedure 1 – Reference Level 1. Set instrument center frequency to DTS channel center frequency. 2. Set the span to ≥ 1.5 times the DTS bandwidth. 3. Set the RBW = 100 kHz. 4.Set the VBW ≥ 3 x RBW. 5.Detector = peak. 6. Sweep time = auto couple. 7. Trace mode = max hold. 8. Allow trace to fully stabilize. 9. Use the peak marker function to determine the maximum PSD level - Measurement Procedure 2 - Unwanted Emissions 1. Set the center frequency and span to encompass frequency range to be measured. 2. Set the RBW = 100 kHz for below 1GHz , 1MHz for above 1GHz( Actual 1 MHz , See below note) 3. Set the VBW ≥3 x RBW(Actual 3 MHz, See below note) 4. Detector = peak. 5. Ensure that the number of measurement points ≥ span/RBW 6. Sweep time = auto couple. 7. Trace mode = max hold. 8.Allow the trace to stabilize (this may take some time, depending on the extent of the span). 9. Use the peak marker function to determine the maximum amplitude level. Note:The conducted spurious emission was tested with below settings. Frequency range: 9 KHz ~ 30 MHz& Band-edge RBW= 100kHz, VBW= 300kHz, SWEEP TIME = AUTO, DETECTOR = PEAK, TRACE = MAX HOLD, SWEEP POINT: 40001 Frequency range: 30 MHz ~ 10 GHz& 10 GHz~25 GHz RBW= 1MHz, VBW= 3MHz, SWEEP TIME = AUTO, DETECTOR = PEAK, TRACE = MAX HOLD, SWEEP POINT: 40001 If the emission level with above setting was close to the limit (ie, less than 3 dB margin) then zoom s…
