Samsung WiDT30Q - User Manual

User manual of WiDT30Q
1. Introduction
WiDT30Q is a USB embedded module compliant with IEEE802.11n standard. The
core chipset is from Qualcomm, part number is AR1021X.
2. Hardware Architecture:
2.1 Main Chipset Information
3.3 Antennas Information
Two SMD antennas supporting both TX & RX.
4. Operational Description
WiDT30Q is the 802.11a/b/g/n RF Module, that acts as a communication hub for users of a
wireless device to connect to a wired LAN.
MIMO type
Product type: WLAN (11b mode: 1TX, 1RX, 11g mode: 1TX, 1RX, Draft n 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
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.
