Transmitter Circuit Board for Remote Controls

Product Specifications

Technical details and manufacturing context for Transmitter Circuit Board

Definition

A transmitter circuit board is a specialized printed circuit board (PCB) designed for use in remote control devices. Its primary function is to generate, encode, and transmit wireless control signals to a receiver. The board integrates essential components such as an oscillator, modulator, amplifier, and antenna interface, all mounted on an FR-4 epoxy laminate substrate with copper traces and a solder mask. It operates by receiving low-power digital command signals from the remote control's microcontroller. The oscillator generates a stable carrier frequency, typically in the ISM band, such as 433.92 MHz. The modulator encodes the digital commands onto this carrier using amplitude shift keying (ASK/OOK). A power amplifier then boosts the signal to a transmission power of up to 10 dBm, which is radiated via an integrated or external antenna. The board is designed for battery-powered operation, with a supply voltage range of 3–12 V DC. It features low power consumption, with a standby current of ≤1 µA and an operating current of ≤15 mA at 3 V supply. The operating temperature range is -20 to 60 °C, and the board dimensions are approximately 20×30 mm with a weight of about 5 g. It offers an ingress protection rating of IP54 per IEC 60529, indicating dust and splash resistance. The PCB material is FR-4, which is flame retardant and complies with IPC-4101. Data rates range from 1 to 10 kbps, depending on the encoding scheme. This board serves as the core electronic component responsible for the remote control's wireless communication function. It is essential to verify model-specific values and standards with the legal manufacturer or supplier, as the listed parameters are typical reference ranges and may vary for specific applications.

Working Principle

The circuit board receives low-power digital command signals from the remote control's microcontroller. An oscillator generates a stable carrier frequency (e.g., 315MHz, 433MHz, 2.4GHz). A modulator encodes the digital command onto this carrier wave. A power amplifier boosts the signal strength before it is fed to an integrated or external antenna for radiation as electromagnetic waves.

Frequently Asked Questions

What is the operating frequency of this transmitter circuit board?

The typical operating frequency is 433.92 MHz, which is in the ISM band commonly used for remote controls. However, other frequencies such as 315 MHz or 2.4 GHz may be available depending on the specific model. Always confirm the exact frequency with the manufacturer or supplier.

What is the maximum transmission power?

The transmission power is typically up to 10 dBm, which is within regulatory limits for unlicensed use. This value may vary by model and regional regulations, so verify the specific product's specifications.

What is the supply voltage range?

The board is designed for battery-powered operation with a supply voltage range of 3 to 12 V DC. Ensure that your power source matches the required voltage to avoid damage.

What modulation type does it use?

The modulation type is Amplitude Shift Keying (ASK) or On-Off Keying (OOK). This is a common modulation scheme for simple remote control applications. Confirm compatibility with your receiver.
