With the support for Grove and Headset interface, you wouldn’t have to worry soldering an external headphone jack or using jumper wires to build an FM radio. But with this integrated module, you’re getting a Grove port and Headset interface. Since the Grove – I2C FM Receiver v1.1 is based on the RDA5807M, it’ll share similar features like it. If you’re already looking for a cheap and simple to use RDA5807 module, we’ve just that here at Seeed! Grove – I2C FM Receiver v1.1 Note: Since the RDA5807 chip itself requires a heavy lot of soldering to be used with an Arduino, we recommend an integrated module for easier interfacing!

The RDA5807M series is the newest generation single-chip broadcast FM stereo radio tuner with a fully integrated synthesizer. Remembered when I mentioned the RDA5807 being a common miniaturized FM receiver? Now let’s take a look at what it’s all about! So long as applications that require high reliability of data transfer and very high uptime, radio communications are picked.
Such modems are key in industrial usages, where real-time data communication is needed.
ModemsįM receivers are found in radio modems, creating private radio networks (PRN) through transferring wireless data across a range of up to tens of kilometers.

For others like Andriod, you can simply download the NextRadio app that allows for the FN chip usage! Satellite Communicationĭata transmission/communication between satellites include FM receiver and transmitter that help with long-distance telephone calls, space station broadcasts, spacecraft direct broadcasting that sends signals of satellite radio receivers for consumers, etc. Here are some of its applications: Smartphonesĭo you know most smartphones on the market have inbuilt FM receivers? Yes indeed! But sad to say for iPhone users, it does not exist as its hardware does not support it. After demodulation, the recovered audio is applied to an audio amplifier block, ending the process by amplifying it to the required level for loudspeakers/headphonesĪlthough FM receivers are made for radio applications, such as radio broadcasting, it’s still applicable and used in a variety of other electronic systems.Demodulation can be in any form of modulation, ranging from amplitude modulation, frequency modulation, etc.The amplified IF signal travels to the demodulator, beginning the process of demodulation.The filtering process filters the immediate frequency outputted from the mixer and amplified it for the next stage.The desired signal is then entered to this block, involving the oscillator and mixer to form a frequency changer circuit, such that required frequency can be converted.The rf amplifier receives the desired signal from the antenna and provides tuning to remove the image signal alongside all unwanted signals on other frequencies.To easily understand how an FM receiver work, let’s explain a simplified FM receiver block diagram! 1. How does FM receiver work? FM Receiver Block Diagram Explained Simplified FM receiver block diagram Amplifier: Used to increase the power of the radio signal.Electronic filters To separate the required radio waves from all the other forms of frequency waves detected.An antenna: To firstly detect the frequency waves.The components of FM receivers and its functionality help achieve that: That’s where an FM receiver comes to play receiving radio waves and converting them into an output where information is usable. Comparing both, FM is less subjected to interference to AM, with better sound quality and higher bandwidth.įor radio communications to take place, it involves three steps as well detecting, receiving, and converting radio waves to the desired information. In radio communications, there are two types of radio transmission FM AM.Based on the earlier introduction, we understand that the FM (frequency modulation) receiver is a device used for Radio communications, but here’s more to it!
