WL500B SMD IC Transceiver IC SOP-8 RF WL500B

Product Overview: A surface-mount, high-performance wireless ASK/OOK superheterodyne receiver integrated circuit designed for low-power and cost-effective wireless data communications. Operating within the 300MHz to 440MHz frequency band, it integrates a low-noise amplifier, mixer, local oscillator, post-amplifier, filter, and data slicing circuitry on a single monolithic chip. It requires minimal external components, features built-in image rejection to suppress interference, and includes a shutdown function to minimize battery drain in power-sensitive hardware configurations.

Core Specifications:

Manufacturer: Shenzhen wireless Technology CO., Ltd (维尔乐思)

Package Type: SOP-8 (Surface Mount)

Features

• High Receiving Sensitivity: Achieves an excellent sensitivity level of minus 110 dBm at both 315MHz and 433.92MHz operating frequencies.

• Ultra-Low Power Consumption: Draws only 3.0mA at 315MHz and 3.1mA at 433.92MHz from a standard 3.3V supply, decreasing to an ultra-low 0.1 microamps in full shutdown mode.

• Fast Startup Velocity: Features an ultra-short startup initialization time of just 2.2 milliseconds, allowing quick duty-cycling for low-power polling products.

• Built-in Image Rejection: Integrates internal image rejection mechanisms to provide high baseline anti-interference performance.

• Flexible Operating Voltage: Functions reliably across a broad DC input supply range from 2.0V up to 5.5V.

• Data Throughput Constraints: Adequately supports wireless data link communication rates up to 8 kbps.

• Strong Electrostatic Defense: Engineered with a high internal ESD protection rating of plus/minus 5kV to enhance product assembly yield and robustness.

Applications

• Wireless Remote Control Systems: Drives data decoding layers for garage door openers, automated barriers, and ceiling fan remotes.

• Remote Keyless Entry (RKE): Implements low-power signal reception pipelines for vehicle and secure compound gating nodes.

• Wireless Smart Home Networks: Interfaces security entry alarms, window sensors, smoke detectors, and automated socket switches.

• Industrial Wireless Telemetry: Manages remote terminal reporting stations, material monitoring sensors, and localized crane control hubs.
