Description

The Summit SWS997SD Rx Module, 4 Integrated Antennas – is a compact, production-ready module designed to mate with the amplifier in active speakers in a Summit Wireless Technology HD audio solution. The Summit Receive Module includes a patent-pending, low-cost, integrated high-gain quad-diversity PCB antenna, which provides superior wireless performance without external antennas. A 2×24, 100 mil standard header provides I2S digital audio, power, and control signals for the amplifier and power supply.

​Features

Summit Wireless Technology Overview

​Summit’s wireless network operates in the uncongested bands of the 5 GHz spectrum previously reserved for radar and weather applications but still strictly enforced.    These offer virtually interference free operation unlike over-crowded WiFi and Bluetooth networks.    The Tx is continually scanning all 24 RF channels, and should its current channel experience poor QoS, then it will coordinate a Tx/Rx hop to a pre-selected open band without interrupting the audio stream.
