DISTRIBUTED AMPLIFIER |
摘要 |
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 MxN 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. |

1. A distributed amplifier comprising:
an input-side transmission line; M (M: integer not less than 2) amplification circuits; M output-side transmission lines provided in accordance with the M amplification circuits; and a combination circuit configured to combine outputs of the M output-side transmission lines; wherein the input-side transmission line includes an input-side serial line formed by connecting in series M×N (N: integer not less than 2) 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 (i: integer not less than 1 and not more than M) amplification circuit take the input node of the ((k−1)M+i)-th (k: integer not less than 1 and not more than N) 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 including a line width with which the phase of the output of the amplifier in each stage agrees to one another. |
