摘要： In an oscillator circuit employing a pattern coil on a printed-wiring board as a resonator circuit, in order to satisfactorily adjust dispersion in oscillation frequencies, an air-core coil wound by more than half a turn and less than one turn is provided so as to be connected to the pattern coil in parallel and planted on the printed-wiring board, and the oscillation frequency is adjusted by adjusting the angle of the air-core coil relative to the printed-wiring board.

摘要： A high frequency signal receiver can prevent higher harmonics other than a necessary higher harmonic from being subjected to frequency conversion so as to interfere with the base band signal in a broadcasting channel frequency band. The receiver has a high frequency signal receiving circuit 1 that comprises an input circuit 3 to which a high frequency signal (RF signal) subjected to frequency conversion from a 12 GHz band to a 1 to 2 GHz band is input, a mixer circuit 4 adapted to frequency convert the signal of 1 to 2 GHz band output from the input circuit 3 into a base band signal, a local oscillation output circuit section 5 adapted to supply a signal of a frequency band to be mixed with the signal output of the input circuit 3 to the mixer circuit 4 and a PLL circuit section 6 to which the source oscillation output signal from the local oscillation output circuit section 5 is input. The local oscillation output circuit section 5 has an oscillation circuit 51, a higher harmonic output circuit 52 that generates the fourth harmonic of the output signal of the oscillation circuit 51 and a resonance circuit 53. It controls both the resonance frequency of the resonance circuit 53 of the local oscillation output circuit section 5 and the frequency characteristic of the input circuit 3 by means of the control voltage output from the PLL circuit section 6 so as to boost the higher harmonic of an order that corresponds to desired broadcasting channel frequency and attenuate higher harmonics of all other orders that appear in other frequency bands that overlap the broadcasting channel frequency in the input circuit 3.
