CXA1019 FM Radio Circuit Diagram

The CXA1019 is a monolithic integrated circuit (IC) that can be used to build a simple FM radio receiver. It is a single-chip FM tuner that includes a front-end amplifier, a mixer, a local oscillator, and an IF amplifier. The CXA1019 also has a built-in audio amplifier, so it can be used to drive a speaker or headphones directly. The following diagram shows a simple FM radio circuit that uses the CXA1019: [Image of FM radio circuit diagram] The circuit consists of the following components: * A telescopic antenna * A variable capacitor (C1) * A diode (D1) * A resistor (R1) * A capacitor (C2) * The CXA1019 IC * A speaker (LS) The telescopic antenna picks up the FM radio signals. The variable capacitor (C1) is used to tune the receiver to the desired station. The diode (D1) rectifies the FM signal, and the resistor (R1) and capacitor (C2) filter out the unwanted frequencies. The CXA1019 IC amplifies the signal and demodulates it to produce the audio output. The speaker (LS) converts the audio signal into sound waves. To build this circuit, you will need the following components: * A CXA1019 IC * A telescopic antenna * A variable capacitor (10-47 pF) * A diode (1N4148) * A resistor (10 kΩ) * A capacitor (100 nF) * A speaker (8 Ω) You will also need a soldering iron, solder, and some wire. To assemble the circuit, follow these steps: 1. Solder the telescopic antenna to the ground pin of the CXA1019 IC. 2. Solder the variable capacitor to the RF input pin and the ground pin of the CXA1019 IC. 3. Solder the diode to the VCO pin and the ground pin of the CXA1019 IC. 4. Solder the resistor to the VCO pin and the IF output pin of the CXA1019 IC. 5. Solder the capacitor to the IF output pin and the audio output pin of the CXA1019 IC. 6. Solder the speaker to the audio output pin of the CXA1019 IC. Once the circuit is assembled, you can test it by turning on the power and tuning the variable capacitor until you find a station. You should be able to hear the audio output from the speaker. The CXA1019 is a versatile IC that can be used to build a variety of FM radio receivers. It is a good choice for beginners who want to learn how to build a radio. It is also a good choice for hobbyists who want to build a simple FM radio receiver.
