1.2.     Operational Description

               The EUT is a Full HD Video Wireless Transmitter Module with a built-in 5GHz transceiver,
          together with Full HD Video Wireless Receiver Module. It has a SIMO design of five channel and one
          slow rate output wireless channel, which generates an upstream channel for data content
          transmissions.
               The data modulation is OFDM, using five antennas to support 4(Transmit) * 1(Receive)
          technology. The device only provided one transmitting speed 31.5Mbps in 20MHz bandwidth mode
          and 63Mbps in 40MHz bandwidth mode. Presents the ultimate solution for converting any High
          Definition (HD) system, including Full HD, into a wireless one. These add-on modules enable
          wireless A/V applications that fit easily into the living room and eliminate traditional A/V wiring. The
          perfect HD video and audio quality and the high robustness are unmatched by any other wireless
          technology and present a true alternative to cable. The WHDI system transmits uncompressed video
          and audio streams wirelessly and thus simplifies and eliminates system issues, such as: lip-sync, large
          buffers and other burdens like retransmissions or error propagation.
               The device can transmit audio and video signal to associate equipment, device will receive signal
          form associate equipment when associate equipment request change operation frequency. The
          AMN2120 WHDITM baseband transmitter chip is the heart of the WV300A WHDI transmitter
          module. The AMN2120 interfaces the A/V source through the WHDI connector. The AMN2120
          includes an internal microcontroller for controlling the physical level. The AMN2120 is based on
          MIMO technology transmitting through up to four output channels. Four digital-to-analog converters
          and one analog-to-digital converter are embedded within the chip. The AMN2120 internal PLL
          accepts an input clock frequency of 40MHz. The input frequency is multiplied and then used as an
          internal system clock. The AMN2120 also generates a 10 MHz reference clock, derived from 40 MHz
          for general use.
               The AMN3110 is a fully-integrated direct conversion MIMO transmitter specifically designed
          for WHDI applications using OFDM modulation in 5.15-5.25GHz and 5.725~5.850GHz. The device
          consists of:
               ‧ Four Complete Downlink Direct Conversion Transmitters.
               ‧ One Uplink Receiver.
               ‧ Integrated Synthesizer.
               ‧ Internal DC Servo Loops.
               ‧ RSSI.
               ‧ IQ Detector.
               ‧ RF and Baseband Control Interface.
               ‧ Power Management Unit.
               ‧ 3-Wire SPI Interface.
               To complete the RF front-end solution, the AMN3110 uses external PA, RF switches, RF Band
          Pass Filters (BPF), RF BALUNs and a few passive components.
               The device antenna are use five FIFA(4TX, 1RX) and printed on PCB, for receiver function there
          are support one external antenna which can instead of printed antenna.




       Test Mode:           Mode 1: Transmit (31.5Mbps 20MBW)
                            Mode 2: Transmit (63Mbps 40MBW)
