Input circuit of an FM tuner made with TDA7212 where the tuning is made only with the mixer oscillator. So the input circuit is fixed tuned around 98 MHz, the mid frequency of the FM range. The IC input is figured by the 75 ohms in parallel with 10 pF. The antenna is figured by HF generator in series with 75 ohms. The input point is the 1 nF condensator.
