Description
88-108MHz FM Radio Kit FM Radio DIY Radio Receiver Kit Fully Discrete Unfinished
Features:
- Full Discrete Classic Circuit: Parameter characteristics can be changed to meet your needs
- Compact size and delicate
- Antenna Amplifier: Amplify the weak signal received by antenna for voltage amplification
- Tunable Filter: Effective filtering of frequencies which are not frequency points
- LC Circuit & LC Oscillator: Generate an adjustable, stable high-frequency signal for your mixer
- LC Notch Filter: Prevent external signals from interfering with IF signals
-10.7MHz IF Amplifier Processing: Frequency selection and amplification of IF signals
- Diode Ratio Frequency Demodulation: Convert FM signal into audio signal that our ears can distinguish
- Audio Amplification, Push-pull Current Amplifier: Voltage and current amplification of weak audio signals from the detector
- Clear Module Labeling: It is easy to distinguish. A good tool for pure analog circuit learning. A must-have learning board for RF engineers
- Military Grade PCB: thick material, ultra-low impedance, durable; the surface adopts special technology makes it easy to weld for green hands
- Superb Circuit Design: The circuit has been optimized through multiple experiments to provide users with a better quality learning kit and enjoy DIY process. RF and audio sections are isolated from each other. The RF impedance is strictly matched to ensure the overall receiving performance.
- High-quality components to ensure users have a better experience to DIY.
Premium Components:
- Capacitors: Quality high-frequency ceramic capacitors feature high precision, low internal resistance, easy identification.
- Resistors: High precision 5-color ring 1/4W resistors outperform normal 2-color resistors
- Inductive Coils: High-purity oxygen-free copper-wound inductors with wire 1mm in diameter
- Triode: Manual matching to ensure excellent performance of triode
- Intermediate Frequency Capacitors: The key intermediate frequency amplification and frequency demodulation parts use high-quality, high-Q, fully shielded IF inductors; Stainless steel shell makes it resistant to rust
