Image trap filter circuit
A varactor diode tuner includes a tunable image frequency trap in its input circuit. The trap is part of a tunable bandpass filter and forms a tapped capacitance matching network for UHF television signal carrier frequencies and a low impedance shunt at image frequencies. The trap is formed of discr...

| Zusammenfassung: | A varactor diode tuner includes a tunable image frequency trap in its input circuit. The trap is part of a tunable bandpass filter and forms a tapped capacitance matching network for UHF television signal carrier frequencies and a low impedance shunt at image frequencies. The trap is formed of discrete capacitors, an inductor and a tunable varactor diode. |
