摘要： PURPOSE:To obtain an excellent isolation characteristic by providing a metallic wire and a capacitor of thin film multi-layer structure in series resonance in parallel with a connection line so as to short-circuit both ends of the connection line at the center frequency. CONSTITUTION:In selecting an inductance 38 of the metallic wire and a capacitance 39 of the thin film multi-layered capacitor so as to be in series resonance at the center frequency, nodes 40, 41 are short-circuited at the center frequency and the length among terminals 21-24 is a 1/2 propagation wavelength lambda8. Then a reflected wave made incident from the terminal 21 appears at the terminals 21-24 in opposite phase, is consumed in resistors among terminals and the isolation characteristic among the terminals is the same as that of the Wilkinson type power distributor and becomes excellent.

CONSTITUTION:An input terminal 1 is connected to distribution terminals 5-8 respectively by means of a distribution constant line 20 having its characteristic impedance ZO and the electrical length set at about 1/4 wavelength in terms of the using frequency. Then the resistances 21 and 22 of resistance values RA and BB are loaded between terminals 5 and 6 and terminals 7 and 8 respectively. Furthermore two resistance 22 are loaded between terminals 6 and 7, and metallic films 23-25 are formed at each junction of resistances 21 and 22, 22 and 22 and 22 and 21 respectively.

摘要： PURPOSE:To vary characteristic impedance and a wavelength shortening rate in the case when the capacitor is regarded as a distribution fixed-number line by forming an epitaxial layer to the lower section of opposite fingers, joining a Schottky with a boundary surface between one finger and the epitaxial layer and forming an ohmic junction to the other finger. CONSTITUTION:The epitaxial layer 13 formed to the lower section of the opposite fingers 4, 5 of the interdigital capacitor used for a microwave integrated circuit, and the Schottky junction surfaces are formed to the boundary surfaces 15 among one fingers 4 and the epitaxial layer 13 and the ohmic junctions to boundary surfaces 16 among the other fingers 5 and the epitaxial layer 13. Consequently, the size of an extent of a depletion layer 18 changes by adjusting a bias power supply 17, and the magnitude C3 of an equivalent variable capacitance 19 depends upon the size of the extent of the depletion layer 18 because the equivalent variable capacitance 19 consists of the coupling capacitance of the fingers 4 and the fingers 5 and depletion capacitance depending upon the extent of the depletion layer. Accordingly, characteristic impedance and the wavelength shortening rate in the case when the interdigital capacitor is regarded as the distribution fixed-number line can be changed by adjusting the bias power supply 17 and altering C3.

摘要： PURPOSE:To obtain the functions of a waveguide-MIC converter and a power distributor simultaneously by inserting MIC substrates which have probe parts for enabling waveguide-MIC conversion from respective corner parts of a square waveguide. CONSTITUTION:At prescribed positions of respective corner parts of the square waveguide 10, openings 11a-11d are formed in prescribed shapes and MIC substrates 12a-12d are inserted into the waveguide 10 through the openings 11a- 11d along a plane containing the waveguide axis and diagonals. On one-side surfaces of MIC substrates 13 used as the substrates 12a-12d, strip conductors 16 provided with probe parts 15 for enabling the waveguide-MIC conversion are formed, and the other-side surfaces which are not inserted into the waveguide 10 are coated with grounding conductors 18; the conductors 16 and 17 form microstrips respectively. This constitution converts an electromagnetic wave propagating in the waveguide 10 in basic propagation mode into propagation mode of MIC and also distribute electric power to the substrates 12a-12d equally.

摘要： PURPOSE:To match an external impedance and a impedance at the terminal of amplifier, by opening one end of a strip conductor connected to the terminal and connecting one end of a strip conductor placed in parallel to the specified terminal of the amplifier and the other end to a resistor and a capacitor for termination. CONSTITUTION:One end of a strip conductor 18 connected to a power supply is opened. One end of a strip conductor 19 in parallel with the conductor 18 is connected to an input terminal 2 of an FET amplifier 1, and the other end is terminated with a resistor 11 and a capacitor 12. Since the capacitance of the capacitor 12 is selected for the reactance so as to be almost zero at microwave band, the strip conductors 18, 19, a dielectric base 8 and a ground conductor 9 form a coupling line 20. This coupling line is a band pass filter and arbitrary characteristic impedance is selected by selecting the width and length of the strip conductors 18, 19 and the interval between the strip conductors suitably.

摘要： PURPOSE:To increase an output while making it easy to distribute and mix electric power signals of a parallel-connected transistor amplifier, by loading a metal partition plate in parallel to the H surface of a rectangular waveguide. CONSTITUTION:The size of rectangular waveguide 1 in the direction of the E surface is divided by two and metal partition plate 2 is loaded in parallel to the H surface; and transistor amplifiers with input circuit 4 and output circuit 8 composed of microwave IC are loaded at waveguide parts 3 partitioned by metal partition plate 2. Signal electric power entering this waveguide 1 is divided by metal partition plate 2 and, after amplified by transistors 5(5a,5b), propagates through waveguide 9 and mixes together at parts D1 and D2 at the end of metal partition plate 2, thereby leading an output signal out. Further, transistors 5 are loaded at intervals one fourth the propagation wavelength in the length direction of the waveguide.
