摘要： PROBLEM TO BE SOLVED: To decrease the number of switches to select a passband and reduce loss when signals in a required frequency band are acquired.
SOLUTION: In a 2-frequency band filter, a first SAW filter 3 that has a passband of 1.4 GHz band and a second SAW filter 4 that has a passband of 1.6 GHz band are arranged parallel, and a phase circuit 5 is provided between the first SAW filter 3 and output terminals 6a and 6b. In the 1.6 GHz band that is a passband of the second SAW filter 4, the first SAW filter 3 functions as a capacitor to allow the phase circuit 5 to parallel resonate and make it as an open impedance. On the other hand, in the 1.4 GHz band that is a passband of the first SAW filter 3, the second SAW filter 4 functions as a capacitor to make a structure that a low-pass filter is connected to the phase circuit 5.

摘要： PURPOSE:To reduce the manufacturing cost, by matching each part of a center conductor to the highest tuning frequency band and narrowering the width of the vertical section for lower tuning frequency band, in the center conductor used for a UHF tuner. CONSTITUTION:A center conductor 1 used for a UHF tuner is provided with a folded part 2 at one end of a horizontal part 3, and the other end is provided with a vertical section 4, and the vertical section 4 is provided with a folded part 6 and a leg 5 fitted to the base. To change the characteristic impedance and the line length, it can only be made by changing the width of the vertical section 4, and the length of the horizontal part 3 and the folded part 6 is also changed by changing the width of the vertical part 4. Thus, in a manufacturing process, the size is matched to the highest tuning frequency band in which the width of the vertical part 4 is widest, and the width of the vertical part 4 is cut off in narrow size for lower turning frequency bands, allowing to reduce sharply the number of metal molds.

摘要： PURPOSE:To make change the characteristic impedance of the resonator easily, by covering the lambda/4 type resonator with a dielectric cylinder and changing the position. CONSTITUTION:When the dielectric substance 6 is apart from the tip of the resonator rod 1, the dielectric constant between it and the console 2 is almost 1. When the dielectric substance 6 coveres the resonant rod 1, the dielectric constant is 1 or more and the resonant frequency gradually decreases. The electric field or electric lines of force of the resonator is vertical to the resonant rod independently of the position of the dielectric substance 6, the density of distribution is not greatly changed, and the current flowing on the surface of the resonant rod 1 and the console 2 is not concentrated on a part but is uniform, resulting in no degradation of Q. Since the thickness of the dielectric substance is constant, even if the cylinder is moved due to vibration, no effect by the dielectric substance is caused. Further, the thickness is controlled and the resonant frequency can be adjusted in good manner.

摘要： PURPOSE:To provide the transmision circuit enabling low-output operations by means of an integrated circuit and to improve cross modulation distoration at the time of low-output operations. CONSTITUTION:At the time of low-output operations, a poitive voltage is impressed to a power save switch terminal SW1, OV is impressed to a power-off switch terminal SW2, only an NPN transistor Q7 is turned in a conducted state, and the voltage of a junction A is lower than the voltage of a normal transmitting state. In such a state, a radio of the resistance values of resistors R1 to R2 and the resistance value of a resistor R1 are selected so that the current of the respective emitters of NPN transistors Q3 and Q4 can be almost 1mA. Thus, a high frequency signal is sequentially amplified by a front stage amplifier 1 and a rear stage amplifier 2 while an infinitesimal bias current flows through a final stage amplifier 2, and radiated from an antenna through a balanced tuning circuit 3.

摘要： PURPOSE:To attain stable operation even when an operating point of a power amplifier is revised by connecting a connecting point of 1st and 2nd amplifiers in cascade connection to a post-stage of a carrier oscillator to the power amplifier via a capacitor with a small capacitance. CONSTITUTION:A phase locked loop circuit 4 generates a control voltage corresponding to a difference between a frequency of an output signal of an amplifier 3 and a frequency of a selected channel and feeds back it to a carrier oscillator 1. Thus, the carrier frequency is controlled to be a frequency corresponding to the selected channel. In this case, the connecting point between the amplifiers 2, 3 is connected to an input terminal of a power amplifier 6 via a capacitor 5 with a small capacitance. Thus, even when the operating current of the power amplifier 6 is changed, the effect is not exerted on the amplifiers 2, 3 and the carrier oscillator 1. Furthermore, since the power amplifier 6 has a higher input impedance than the impedance interposed to the connecting point of the amplifiers 2, 3, an output signal of the amplifier 2 is delivered at a sufficient level even when the capacitance of the capacitor 5 is small.

摘要： PURPOSE:To minimize an unbalanced component and to amplify a signal with a high gain by joining the output currents of respective output terminals temporarily by a precedent-stage differential amplifier and shunting the joined current to the input terminals of a following-stage differential amplifier. CONSTITUTION:A composite tuning circuit 3 which forms DC short circuits between the output terminals of the precedent-stage differential amplifier 1 and the input terminals of the following-stage differential amplifier and also limits the bands of unbalanced AC signals generated at the output terminals of the precedent-stage differential amplifier 1 and sends the currents to the input terminals of the following-stage differential amplifier 2 is interposed. In this case, the output signals obtained from the output terminals of the precedent-stage differential amplifier 1 are inputted to the composite tuning circuit 3 and band-limited, and only the balanced components of the output signals are extracted and inputted to the input terminals of the following- stage differential amplifier 2. Then the following-stage differential amplifier 2 performs the differential amplification of the balanced signals from the composite tuning circuit 3 and the obtained output signal is band-limited by the tuning circuit consisting of a coil 41 and a capacitor 42 and outputted through a capacitor 44.
