Component Specifications

Definition
A hybrid electronic component that integrates an RF antenna for wireless communication (typically in 2.4GHz, 5GHz, or sub-GHz bands) with an infrared LED for short-range optical data transmission or remote control signaling. This component enables both radio frequency and infrared communication capabilities in industrial wireless transmitters, supporting protocols like Wi-Fi, Bluetooth, Zigbee, or proprietary RF alongside IR remote control functions.
Working Principle
The antenna portion operates on electromagnetic wave propagation principles, converting electrical signals to radio waves (transmit) and vice versa (receive). The IR LED emits infrared light (typically 850-940nm wavelength) when forward-biased, with intensity modulated by the input signal to encode data. Both functions share common power and control circuitry but operate on different physical layers.
Materials
Antenna: Copper trace on FR-4 PCB substrate or flexible PCB with nickel/gold plating; optional ceramic dielectric for miniaturization. IR LED: Gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) semiconductor chip in clear epoxy or silicone encapsulation. Housing: ABS or polycarbonate plastic with RF-transparent window.
