RC-TXFSK-433

RF Transmitter Overview

The RC-TXFSK-433 is a 433.92MHz FSK transmitter module manufactured by RadioControlli, designed for home and building automation applications. It operates within a supply voltage range of 2.2V to 3.6V and delivers an output power of 10dBm at a data rate of 50kbps. The module features a 6-DIP through-hole package with dimensions of 20.32mm x 11.43mm. It includes a crystal oscillator for frequency stability and supports a power-down mode. The operating temperature range extends from -25°C to 80°C, with a transmitting current of 21mA.

RF Transmitter Feature Summary

• Supports Frequency Shift Keying (FSK) modulation for reliable wireless transmission in security and automation systems.
• Integrates a built-in crystal oscillator to ensure stable frequency operation without external components.
• Includes a dedicated power-down mode to minimize energy consumption when the device is idle.
• Utilizes a standard 6-DIP through-hole package for straightforward integration into existing circuit boards.

RF Transmitter Applications

• Home automation systems requiring wireless control signals
• Building automation infrastructure for remote monitoring
• Wireless security system transmitters

RF Transmitter Procurement Notes

Verify that the specific batch matches the 6-DIP through-hole package specification and confirm the operating voltage aligns with the 2.2V to 3.6V range. Ensure the supplier provides documentation confirming the 10dBm output power and 433.92MHz center frequency. Check for compliance with the stated -25°C to 80°C operating temperature limits to guarantee performance in the intended environment.

RF Transmitter Selection Notes

Select this module when a fixed-frequency FSK transmitter is required for short-range wireless communication. It is suitable for designs needing a low-profile through-hole component with integrated frequency synthesis. Consider the 21mA transmitting current for power budget calculations and ensure the host system can accommodate the 6-DIP footprint.

RF Transmitter Part Context

This component belongs to the RadioControlli RF transmitter series, which offers various frequency options for different regional regulations. The RC-TXFSK-433 specifically targets the 433.92MHz ISM band, commonly used in Europe and other regions for industrial, scientific, and medical applications. It serves as a direct replacement for older fixed-code transmitters where FSK reliability is preferred.

RF Transmitter Replacement Considerations

Direct substitutes include the RC-TXFSK-433.42 variant, which operates at 433.42MHz. Other models in the series may offer different frequencies or pinouts; verify compatibility before substitution. Ensure any replacement maintains the same 6-DIP package and voltage requirements.
