>< Here is a compact low cost FM radio circuit using IC TDA 7000. This circuit is designed as per the data sheet and the result is excellent.Ideal for all category of electronic enthusiasts.
The TDA7000 is a monolithic integrated circuit for mono FM portable radios, where a minimum on peripheral components is crucial. The IC TDA 7000 has a Frequency-Locked-Loop system with an intermediate frequency of 70 kHz. The intermediate frequency selectivity is achieved by active RC filters. The only function which needs alignment is the resonant circuit for the oscillator, thus selecting the reception frequency. Spurious reception is avoided by means of a mute circuit, which also eliminates too noisy input signals. Special steps are taken to meet the radiation requirements.

Sirkuit ini dirancang sebagai per lembar data dan hasilnya adalah excellent.Ideal untuk semua kategori penggemar elektronik.TDA7000 adalah sirkuit terpadu monolitik untuk radio FM mono portabel, di mana minimal pada komponen perifer sangat penting. IC TDA 7000 memiliki sistem Frekuensi-Locked-Loop dengan frekuensi menengah dari 70 kHz. Selektivitas frekuensi menengah dicapai oleh filter RC aktif. Satu-satunya fungsi yang perlu keselarasan adalah sirkuit resonan untuk osilator, sehingga memilih frekuensi penerimaan. Penerimaan palsu dihindari dengan cara sirkuit bisu, yang juga menghilangkan sinyal input terlalu berisik. Langkah khusus diambil untuk memenuhi persyaratan radiasi.
