Hi guys..
The following is an initial part of a transistor Vhf tuner involving a balun used to balance an unbalanced line and an impedance matching network consisting of the tapped coil L1 and shunting capacitor of 10 pf and 15 pf matching a 75Ω antenna impedance to the rest part of the circuit ..
My queries are..
1. How does this impedance matching network works..??..Why two capacitors are used instead of one..??
2. What is the role of 470 pf capacitors ??
