    摘要: Transmission outputs of a plurality of transmission branches (101, 102) are extracted by coupler sections (161, 162). Branch detectors (121, 122) respectively detect the levels of the extracted signals of the respective transmission branches and a combination detector (130) detects an output obtained by combining two extracted outputs from the transmission branches by a signal combining section (110). An amplitude error is detected and corrected by comparing output levels of the branch detectors (121, 122), and a phase error is detected and corrected by an output level of the combination detector (130).

    摘要: When a power supply switch is turned on and an RF signal and an LO signal are input to a bipolar transistor, a mixed signal of both signals is output as an IF signal. When the power supply switch is turned off, the bipolar transistor operates as two diodes connected between a base terminal and an emitter terminal and between the base terminal and a collector terminal. When the IF signal and the LO signal are input, the input signals are mixed with each other by the diodes and the RF signal is output. Accordingly, one frequency conversion has a plus conversion gain and when bidirectional frequency conversion is performed by the use of one frequency converter, an external circuit such as a signal path switching switch is not necessary.

    摘要: A pulse signal reception device of a comparatively simple configuration detects a signal sampled at an optimal clock timing for a pulse modulation signal having a signal width shorter than a symbol frequency. In this device, a time division unit (103) samples a data signal at a clock signal rise edge and outputs the sampled data signals to counters (104-1 to 104-3), respectively. The counters (104-1 to 104-3) count the number of High levels when the data signal becomes High level within a predetermined period, and a maximum value detection unit (105) outputs maximum data string information on a data string counted by a counter in which the maximum number of High levels has been detected among the counters (104-1 to 104-3) to a selection data judgment unit (106). The selection data judgment unit (106) judges which data string sampled at a particular timing is to be selected as a demodulation data string.

    摘要: A transmitting method and a transmitter apparatus, which need no manual adjustment, are disclosed. A delay amount is automatically adjusted such that an out-of-band distortion component of a transmission signal is minimized, and a correct timing is produced by the method and the apparatus. In this transmitter apparatus, a first delay adjusts a control timing over a voltage that controls a power amplifier, and a distributor distributes an output from the power amplifier in order to feedback parts of the output. A distortion adjusting units calculating a distortion component of the transmission signal by using the signal fed back by the distributor, and adjusts automatically a delay amount of the first delay so as to minimize the distortion component. This structure allows eliminating manual adjustment, and obtaining high power-efficiency with fewer distortions.

    摘要: A strip-line filter is provided with upper- and lower-stage resonators having the same electromagnetic characteristics. Each of the resonators has a one-wavelength square-shaped strip line and four open-end transmission lines connected to four coupling points A,C,B and D (or E,G,F and H) of each resonator which are spaced 90 degrees in electric length in that order. The square-shaped strip lines have a pair of parallel coupling lines closely placed in parallel to each other to electromagnetically couple the resonators. Therefore, the filter can be manufactured in a small size. A first microwave resonated in each resonator is electromagnetically influenced by two open-end transmission lines connected to two coupling points A and B (or E and F), and a second microwave resonated in each resonator is electromagnetically influenced by two open-end transmission lines connected to two coupling points C and D (or G and H). Therefore, resonance wavelengths of the microwaves can be longer than a line length of each square-shaped strip line. Also, the resonance wavelengths can be adjusted by trimming the transmission lines. Also, because all constitutional elements are made of strip lines, the filter can be made plane.
