A few years ago, I decided to build a solid-state stereo FM receiver. My and FM receivers were quite a success, but I wanted to try my skills at a solid-state version. Among the many FM radio ICs (integrated circuits) on the market, I wrongly focused on the FM tuner, the stereo decoder and the stereo amplifier. These SMD (surface-mount) ICs were hard to obtain and difficult to solder, so my project ended up on paper and never saw the light.
I was searching the internet for receiver projects one day when I landed on Patrick Cambre's website. Patrick described a 2-IC stereo FM receiver he built with the SMD (Surface mount) version of the TEA5711T and TDA7050T ICs. His receiver was based on the application circuit of the TEA5711T, which was simple and easy to implement. Patrick used a printed circuit to connect the miniature ICs, but since I was going to use construction, I decided to use the DIP (Dual inline) version of the ICs for my receiver. Obtaining the larger TEA5711 and TDA7050 was not an easy matter as they were out of production, but I eventually located and purchased a bunch of them with the help of a friend in Germany. I was finally ready to build my first solid-state stereo FM receiver!
