Title:
分布型増幅器
Document Type and Number:
Japanese Patent JP6565231
Kind Code:
B2
Abstract:
A distributed amplifier includes: an input-side transmission line; M amplification circuits; M output-side transmission lines; and a combination circuit configured to combine outputs of the M output-side transmission lines; wherein the input-side transmission line has an input-side serial line formed by connecting in series M×N unit transmission lines each including the same line length, and an input-side terminating resistor, the M amplification circuits each includes N amplifiers and the N amplifiers of the i-th amplification circuit take the input node of the ((k - 1) M + i)-th input-side transmission line to be the input, and the output-side transmission line includes an output-side serial line including N transmission lines each being connected in series between the neighboring outputs of the N amplifiers and each having a line width in which the phase of the output of the amplifier in each stage agrees with one another.
