Abstract

PURPOSE:To avoid the reflection of output, by coupling the microwave IC to the microstrip line, through the package construction for microwave IC so that the characteristic impedance of the space exposed part of the inner conductor is 50OMEGA. CONSTITUTION:The microwave IC2 is mounted on the metal-made base 1 such as copper, the conductor block 9 of U-shape is located closingly at the end of the IC board 8, and the bottom is fitted to the base 1. Through hole is provided at the concave wall of the block 9 and the bushing 10 of dielectric substance is inserted, and one end of the inner conductor 3 folded and shaped in L-shape is inserted to the hole of the bushing 10 and it is connected to the microstrip line 5. Another end of the inner conductor 3 is connected to the terminal 11 provided with the base 1, the part exposed at the space in the middle is located in the concave space of the block 9 and a capacitance is formed between the wall of the block 9 and it, to constitute the characteristic impedance of 50OMEGA which is determined with Z0=(L/C)<1/2>.
