Abstract
【解決手段】信号が入力される信号線路入力端子12から能動素子10の入力端子に至る入力線路11と、能動素子の出力端子から信号を出力する信号線路出力端子22に至る出力線路21とを備えた回路に設けられ、能動素子に直流電力を供給する基板上に形成されたバイアス回路において、直流電力が供給される給電線路27aと、出力線路と給電線路とを接続する曲げ加工された架橋形の金属構造体20と、給電線路と金属構造体との接続点と接地との間に設けられた容量素子26を備えている。
【選択図】図1
Description
(B)信号がバイアス回路と信号線路との接続点で反射されないこと
上記(A)および(B)を満たすためには、信号の周波数においてバイアス回路が開放状態、つまり非常に高いインピーダンスになることが必要である。特に(B)では、入力される信号と反射される信号の関数である電圧定在波比VSWR(Voltage Standing Wave Ratio)が1.2以下、または反射損失が20.83[dB]以上になることが要求される。
図4に示すように、本実施例1に係るバイアス回路の方が、基板上の配線パターンを用いてλ/4線路を構成したバイアス回路よりも広い帯域においてVSWR≦1.2以下である反射特性≦−20.83[dB]となっている。具体的には、本実施例1に係るバイアス回路では、反射特性≦−20.83[dB]となる周波数範囲が13.015〜15.561[GHz]となっており、SNGで使用する周波数範囲13.75〜14.5[GHz]よりも十分に広い帯域において有効なバイアス回路であることを確認できる。したがって、本実施例1に係るバイアス回路によれば、従来は実現が困難であった基板の誘電率、基板厚および配線パターンの寸法の変動による周波数特性のばらつきを吸収することが可能となる。
、27a‥給電線路。
