Abstract:
A high-frequency front end circuit includes a frequency fixed filter and frequency variable LC filters, and these are connected in series in a signal transmission path. The frequency fixed filter transmits high-frequency signals in a frequency band of a communication band and attenuates high-frequency signals outside the frequency band of the communication band. One of the frequency variable LC filters is an LC filter and attenuates unnecessary wave frequencies in the frequency band of the communication band. Another one of the frequency variable filters is a resonator filter that passes high-frequency signals in a frequency band of a selected channel and attenuates high-frequency signals in frequency bands of adjacent communication channels of the selected channel.

Claim (Index 16):
The high-frequency front end circuit according to  claim 7 , wherein the second variable filter includes:\n an input terminal; an output terminal; a first series arm LC filter circuit connected between the input terminal and the output terminal, a first end of the first series arm LC filter circuit being connected to the input terminal and a second end of the first series arm LC filter circuit being connected to the output terminal; a first parallel arm LC filter circuit connected between the first end of the first series arm LC filter circuit and ground; and a second parallel arm LC filter circuit connected between the second end of the series arm LC filter circuit and ground, wherein each of the first parallel arm LC filter circuit and the second parallel arm LC filter circuit comprises a variable capacitor and an inductor connected in series, and wherein the first series arm LC filter circuit comprises a fixed capacitor, an LC series circuit, and an LC parallel circuit, wherein:\n the fixed capacitor is connected in parallel with the LC series circuit, \n the LC series circuit comprises a fixed capacitor and an inductor connected in series, the fixed capacitor being connected to the input terminal and the inductor being directly connected to the output terminal or connected to the output terminal with another inductor interposed between the inductor and the output terminal, and \n the LC parallel circuit comprises a variable capacitor and an inductor connected in parallel and is connected at one end to a node between the inductor and the fixed capacitor of the LC series circuit, and at another end to ground.
