RXB12 Superheterodyne Wireless Receiver Module 315/390/418/433MHz Stable Signal for Garage Door Remote Alarm Systems

Description: 1. Top-Tier Signal Reception Performance: Built with integrated Automatic Gain Control (AGC) circuit and PLL phase-locked loop local oscillation structure, it achieves -107dBm reception sensitivity without frequency offset, effectively removing signal phase distortion caused by unstable signal strength. It maintains stable signal reception even in complicated environments without any reception blind areas, and can be used as a direct replacement for infrared receivers. 2. Industry-Leading Low Power Design: Featuring optimized imported RF chip circuit design, it works with a wide 3.0V-5.5V operating voltage, with operating current as low as 2.5mA@315MHz. It effectively lowers device power consumption, which is perfect for battery-operated portable devices and significantly extends the battery life of your devices. 3. Reliable Anti-Interference & Universal Compatibility: Adopting professional stray radiation suppression process, it offers excellent anti-interference capacity and supports multiple modules running at the same time. It is applicable for harsh industrial control scenarios, lowers product certification costs, and supports stable large-scale deployment. 4. Extreme Temperature Resistant Performance: Adopting industrial-grade electronic parts, it runs stably in the temperature range from -30℃ to 85℃. It functions normally under extremely cold or high-temperature environments, suitable for outdoor, vehicle-mounted, industrial control scenarios with big temperature variations, and ensures long-term reliable operation. 5. Plug-and-Play Integration No External Components Required: Pre-integrated with full superheterodyne receiving circuit, no extra external components are required, and it directly outputs standard CMOS signals for external decoding. It greatly simplifies your product development workflow, cuts down R&D cycles, helps you realize wireless functions for your products quickly and boost product added value.
