Wireless Transceiver Module for Multi-Room Audio

Product Specifications

Technical details and manufacturing context for Wireless Transceiver Module

Definition

This wireless transceiver module is a specialized electronic component designed for use in multi-room audio speaker systems. It handles both transmission and reception of digital audio signals, enabling synchronized playback across multiple speakers without physical connections. The module serves as the core communication interface between the audio source and individual speakers, converting digital audio into radio frequency (RF) signals for transmission and performing the reverse process for reception. It typically uses protocols such as Wi-Fi, Bluetooth, or proprietary wireless standards, and includes modulation/demodulation circuits, RF amplifiers, and digital signal processing components to maintain audio quality and synchronization across multiple rooms. The module is intended for integration into speaker systems by original equipment manufacturers (OEMs) and system integrators. It is not a finished consumer product but a component that requires proper design-in and validation. Key parameters include an operating frequency in the 2.4–2.4835 GHz ISM band, adjustable transmission power from 0 to 20 dBm, receiver sensitivity from -90 to -95 dBm, and data rates from 1 to 3 Mbps. It operates on a supply voltage of 1.8–3.6 V DC, with current consumption ranging from 40–180 mA during transmission and 20–40 mA during reception. The module is rated for industrial-grade operating temperatures from -40 to 85 °C and a non-condensing humidity range of 10–90% RH. It offers digital audio and control interfaces including UART, I2S, and SPI, and supports both PCB and external antennas via an IPEX connector. The compact SMD package measures 13.5 × 13.5 × 2.0 mm and weighs approximately 1.5 g. Certifications such as FCC, CE, and IC are listed as references for market access, but actual compliance must be verified for the specific model and application. Always confirm model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

The module converts digital audio signals into radio frequency (RF) signals for transmission and performs the reverse process for reception. It uses modulation/demodulation circuits, RF amplifiers, and digital signal processing components to maintain audio quality and synchronization. The operating frequency is in the 2.4 GHz ISM band, and it supports adaptive frequency hopping to mitigate interference. The module can operate in both transmit and receive modes, with adjustable transmission power to balance range and power consumption. It interfaces with a host processor via UART, I2S, or SPI for digital audio and control data. The antenna can be either a PCB trace or an external antenna connected via an IPEX connector. The module's performance parameters, such as receiver sensitivity and data rate, are specified for reference and must be validated in the target system.
