4. A superheterodyne receiver is to tune the range 88.1MHZ to 107.1MHZ. The RF circuit inductance is 1µH. The IF is 1800kHz. High side injection is used. a. If the minimum capacitance of the variable capacitor of the local oscillator is 0.5pF, calculate the maximum capacitance b. If the receiver has a single converter stage, calculate the image frequency of 101.3MHZ c. Calculate the IFRR (in dB) of (b) if Q of the preselector is 50
