Introduction Chapter 1 Introduction 1.
Introduction • RF characteristics: • MIMO technology, using 5GHz unlicensed band, 18MHz bandwidth. • Coexists with 802.11a/n and 5.8GHz cordless devices. • Support for Automatic Transmission Power Control (ATPC). • No line of sight needed between transmitter and receiver. It has a range of over 30 meters, suitable for almost any room. • 14mW typical transmission power. • Maximum 45mW transmission power. • Power requirements: • 3.3V (±5%), ~5.
Overview Chapter 2 Overview The HM500 WHDI Video Source Unit (VSU) is designed to modulate and transmit downstream video and audio content over the wireless medium and receive a control channel over the wireless upstream. The modulation uses 18MHz bandwidth and is carried over the 5GHz unlicensed band. Figure 1 displays a block diagram of the HM500. The inputs to the VSU are digital uncompressed video, digital audio and control, all via the WHDI connector.
Overview The main building blocks of the HM500 are as follows: • AMN2110 WHDI Baseband Transmitter, as briefly described on page 4 • STM32F103RBT6 Mini-MAC µController, as briefly described on page 4 • MAX2828 5GHz (802.11a) Transceiver, as briefly described on page 5 • Power Amplifier (PA), as briefly described on page 5 • Board Connector (WHDI Connector), as described on page 5 • EEPROM, as described on page 5 • 40MHz Clock Gen, as described on page 5 2.
Overview 2.3 MAX2828 5GHz (802.11a) Transceiver The VSU has four MAX2828 chips embedded in it. The MAX2828 is a single-chip, RF transceiver IC designed specifically for single-band 4.9GHz to 5.875GHz, OFDM, 802.11 WLAN applications. It includes all the circuitry necessary to implement the RF transceiver function, providing a fully integrated receive path, transmit path, VCO, frequency synthesizer and baseband/control interface.
