MikeMIok i get the idea. At higher received frequencies the image rejection would not be very good with a Khz IF frequency.


The design in Fig 10 on page 8 of the data sheet is how it should be used as an AM only receiver. Where are all the rest of the parts?

Tda108 newer version is the TDA that is in a “radio” sold for one dollar at The Dollar Store and it also has terrible performance. Which will have quite a low Q as it is loaded by the antenna and the input of the IF amplifier which you are using as an RF amplifier.

Started by chemelec Today at 4: You can obviously make an AM only radio with that IC, but you still need all the AM parts to make it work – as it’s a superhet you need a local oscillator, IF, and front end tuning. Media New media New comments Search media. tda103

Note that the ‘circuit’ you copied says it’s for MF and a crap performer at thataltering it for short wave will make it even worse. Of course the TDA produces clear sound without much hiss or noise, it is FM, not AM and it cuts high audio frequencies to reduce its hiss.

Forums New posts Search forums. Playstation 1 motherboard housing td1a083 off, help! The way you are using the TDA in post 1 is not the way it was designed to be used. I think it would be cheaper to buy a ready made short wave receiver. You would need would need to use a variable frequency local oscillator. Welcome to our site! I am not clear about your location. It is designed to be used as a superhet receiver which means that the selectivity is provided in the IF stages.


Its spec’s also show horrible distortion and noise. Where do you buy the obsolete radio ICs you are talking about? But it was designed a long time ago with only a single tuned LC circuit when there were few FM radio stations to cause poor selectivity. Thread starter patric44 Start date Aug 3, Tags am radio radio short wave radio circuit tda You would need to use a two gang tuning capacitor so the input tuned circuit was tuned to either Khz above or below the local oscillator requency Depending on weather you wanted the local oscillator above or below the received frequency.

You must log in or register to reply here. This design is for a fixed frequency as it uses a crystal controlled local oscillator.

If you are in the US then I would think you could get a short wave radion for a similar price to the price in the UK. For a better experience, please enable JavaScript in your browser before proceeding.

Your profile shows your location as the United States but in another thread you say it is Egypt. Here in Canada a half-decent FM radio has many tuned LC circuits so that it can select only one local FM radio station from the 50 or more local stations here.

The only selectivity tdaa1083 your circuit is one tuned circuit on the input.
