摘要： PURPOSE:To eliminate the need for a choke coil and to constitute an oscillation circuit on a plane by supplying power from other terminal than a collector terminal to a collector terminal in a tuning circuit comprising a tuning line, a capacitor and a varactor diode connecting to the collector terminal of a transistor(TR). CONSTITUTION:A tuning circuit comprising a tuning line 15, a capacitor 6 and a varactor diode 7 connects to a collector terminal of a TR 1, the power is supplied to the collector terminal from other terminal than the collector terminal of the tuning circuit. The capacitance of the varactor diode 7 is increased at a low oscillating frequency and the impedance of the terminal other than the TR 1 of the tuning circuit is low. On the other hand, since the capacitance of the varactor diode 7 is decreased conversely in a high oscillating frequency, the impedance is kept high and since the frequency is high, a minute inductance 19 of the pattern is inserted between the power terminal 16 and the tuning line 15 because the frequency is high and the impedance of the power terminal 16 is kept high when viewing from the tuning line 15 and the oscillator is made stable.

摘要： PURPOSE:To facilitate the mounting of an adjusting stub and minute adjustment and to decide the range optionally by providing plural stubs with a proper interval in the same direction to a microstrip line of a dielectric base and connecting the stubs. CONSTITUTION:The length of the adjusting stubs 2 is selected so as not to be resonated at a 1/2 wavelength of the operating frequency or below to a transmission line 1 so as to be coupled with an electric field sufficiently and the plural stubs 2 are coupled with a gap. the stubs 2 are not directly connected to the transmission line 1 but the subs 2 are connected, then the electric field coupling is changed with the transmission line 1. Thus, the stubs 2 are not directly connected to the transmission line 1, then a slight impedance change is formed very easily and the minute adjustment with slight impedance change is attained and the high frequency plane circuit adjusting device for NF adjustment of a high frequency amplifier is obtained.

摘要： PURPOSE:To miniaturize the device by providing a band-stop filter stopping the center frequency of a BPF of a reception section between the modulation circuit of a transmission section and the BPF. CONSTITUTION:The reception wave inputted from an antenna 23 is inputted from an input terminal 1 to pass a 1st BPF 2, and frequency-converted by a frequency modulation circuit 3, then demodulated by a demodulation circuit 5. A voice is outputted from a speaker 25 through an output terminal 6. On the other hand, a voice signal inputted to a microphone 24 is modulated by a modulation circuit 8 through a 2nd input terminal 7 in a transmission section. The output signal of the circuit 8 is power amplified by an output amplifier 9. So as to prevent the signal from entering tone reception section, a band stop-filter 10 stops the center frequency of the BPF 2. Then the signal passes the BPF11 and sent from an antenna 23 through the input terminal 1. Thus, the bidirectional communication device unnecessitating deuplexers can be constructed.

摘要： PROBLEM TO BE SOLVED: To integrate the circuits for the processing unit onto one and same semiconductor substrate and to improve the C/N of a conversion frequency use signal. SOLUTION: An input signal 71 is multiplied with a separation frequency conversion signal 72A by a 1st separation frequency multiplier 13 on one hand, the input signal 71 is multiplied with a 3rd conversion signal 72B having a phase difference of 90 deg. to the signal 72A at a 2nd separation frequency multiplier 18 on the other hand, resulting that the input signal 71 is decomposed as color difference signals. The color difference signals are given to 1st or 2nd low pass filters 14, 19 passing low frequencies, where undesired high frequency components are eliminated, the resulting signal passes respectively through 1st or 2nd comb-line filters 15, 20. The output of the filter 15 is multiplied with a decoding frequency conversion signal 73A at a 1st decoding frequency multiplier 16, and the output of the filter 20 is multiplied with a decoding frequency conversion signal 73B with a phase difference of 90 deg. with respect to the signal 73A at a 2nd decoding frequency multiplier 22 and they are respectively decoded into a chroma carrier frequency band.
