3. Operational Description
WYSBMVGX4 is the 802.11 g/n(20,40MHz) RF Module that acts as a communication controller for
users of a wireless device to connect to Mobile Device e.g. Smartphone, Tablet, etc. This uses 802.11
g/n(20MHz) network with 11 channels,802.11 n(40MHz) network with
9 channels at 2.4GHz
- Features
• Low power dissipation
• CMOS and low-swing sine wave input clock
• 12, 13, 19.2, 24, 26, 38.4, and 52 MHz crystal clock support with auto-frequency detection using external
32.768 KHz CMOS-level sleep clock
• Sleep and standby modes for low power operation
• Fully compatible with Marvell Power Management device(s)
• 802.11 g/n(20,40MHz) compliant, with maximum data rates up to 72 Mbps (20 MHz channel) and 150
Mbps (40 MHz channel)
• 802.11g/n 1x1 SISO with on-chip Marvell SISO RF radio
• PHY data rates up to 150 Mbps
- 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,
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.
- 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.
