Title:
POWER DISTRIBUTING CIRCUIT AND POWER AMPLIFIER
Document Type and Number:
Japanese Patent JP3464383
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To ensure the ideal characteristics of a Wilkinson power distributing circuit, simple connection with another microwave circuit or the like, and realizability ready, in a power distributing circuit suitable for the amplification of a signal with a microwave band and a millimeter wave band.
SOLUTION: This power distributing circuit is provided with distribution lines 3a and 3b branched into two in the neighborhood of an input terminal 2 which is electrically conducted to an input line 1. The distribution lines 3a and 3b are electrically conducted with output lines 5a and 5b in each output terminal 4a and 4b. This circuit is provided with two connection lines 10a and 10b electrically conducted with the output terminals 4a and 4b of the distribution lines 3a and 3b respectively. An isolation resistance 6 is connected between the two connection lines 10a and 10b. The branching part of the distribution lines 3a and 3b is provided with a stab 11.
