SYN115 F115 433M ASK Wireless Transmission Module

SYN115 F115 433M ASK Wireless Transmission Module is a high-performance, compact UHF transmitter designed specifically for the 433.92 MHz frequency band using Amplitude Shift Keying (ASK) modulation. This module utilizes the SYN115 high-integration chip, which simplifies the design of wireless data links by requiring very few external components. Consequently, it provides a stable and cost-effective solution for short-range wireless communication. The device operates across a wide voltage range, ensuring compatibility with various battery-powered systems and microcontrollers. Furthermore, its excellent frequency stability and low harmonic emissions allow it to pass stringent wireless regulatory standards easily. Therefore, you can rely on this module to deliver consistent data transmission for remote control and telemetry applications.

Key Features:

• High Integration: The module uses the SYN115 CMOS IC, which incorporates a complete PLL-based transmitter, reducing the need for external tuning components.
• ASK Modulation: It supports Amplitude Shift Keying (ASK/OOK), making it compatible with a vast array of standard 433 MHz receivers.
• Wide Operating Voltage: The module functions reliably between 1.8 V and 3.6 V, making it ideal for direct operation from lithium or alkaline batteries.
• Low Power Consumption: It draws minimal current during transmission and enters a low-power state when idle to extend battery life.
• Compact Form Factor: The small PCB footprint allows for easy integration into handheld remote controls and space-constrained IoT devices.
