An RF module (short for radio-frequency module) is a (usually) small electronic device used to transmit and/or receive radio signals between two devices. In an embedded system it is often desirable to communicate with another device wirelessly .

This module contains an RF tuned circuit that works like a filter, blocking out unwanted signals that aren’t in the 433MHz range. It also has several operational amplifiers (OP Amps) that increase the strength of the received radio waves before processing them.

An RF module allows customers to develop their own wireless products without having to worry about radio frequency design, test and measurement.

Mouser is an authorized distributor for many RF module manufacturers including Analog Devices, Digilent, KrakenRF, Lime, Qorvo, Texas Instruments & more. Please view our large selection of RF modules below.

RF modules are partially finished circuits that can be incorporated into larger designs. They include receivers, transmitters, and transceivers. RF modules use several different modulation methods and radio techniques. On-off key (OOK) modulation turns a signal on or off.

The transceiver module furnishes a complete RF subsystem that can be utilized to transmit and receive data at up to 500Kbps from any standard CMOS/TTL source. Extensive hardware support is provided for packet handling, information buffering, burst transmissions, and …

An RF module is a device that is used to transmit and receive radio signals between two devices. They may use one or several wireless connectivity protocols like Bluetooth, Wi-Fi, LoRa, Zigbee or can even proprietary protocols.

A Radio Frequency (RF) module is an electronic device that transmits and/or receives audio signals between two devices. It operates at a radio frequency of 20 kHz to 300 GHz. But how does the RF module work?

Highly integrated RF front-end modules feature a minimal external bill of materials. The matched input and output interfaces, along with internal filtering, provide savings in both space and external bill of materials costs. These modules operate over a wide supply range, accommodating the entire battery spectrum. ...

Dec 9, 2010 · This RF module comprises of an RF Transmitter and an RF Receiver. The transmitter/receiver (Tx/Rx) pair operates at a frequency of 434 MHz. An RF transmitter receives serial data and transmits it wirelessly through RF through its antenna connected at pin4.
