Description
実施の形態に係る電力増幅器10の模式的平面パターン構成は図1に示すように表され、比較例に係る電力増幅器10aの模式的平面パターン構成は図2に示すように表される。実施の形態に係る電力増幅器10は、MMIC基板1上に形成されている。同様に、比較例に係る電力増幅器10aは、MMIC基板1a上に形成されている。
実施の形態に係る電力増幅器の模式的回路ブロック構成は、図14に示すように、高周波プローブパッドGPにボンディングワイヤBW1を介して接続されるメタルプレートMPと、高周波プローブパッドGPに接続された増幅ユニット20とを備える。
例えば、周波数を低域と高域に分け、高域増幅器と低域増幅器を電力分配器・電力合成器を介して並列接続することで、広帯域化を図ることができ、また出力特性の平坦度を良好にすることができる。
実施の形態に係る電力増幅器10に適用可能なFET150の模式的平面パターン構成は、図15に示すように、MMIC基板1上に配置され、それぞれ複数のフィンガーを有するゲートフィンガー電極124、ソースフィンガー電極120およびドレインフィンガー電極122と、MMIC基板1上に配置され、ゲートフィンガー電極124、ドレインフィンガー電極122ごとに複数のフィンガーをそれぞれ束ねて形成したゲート端子電極Gおよびドレイン端子電極Dと、MMIC基板1上に配置され、ソースフィンガー電極120の複数のフィンガーをそれぞれオーバーレイコンタクトにより接続したソース端子電極Sとを備える。ここで、図示は省略するが、ソース端子電極Sの下部にはVIAホールが配置される。図1もしくは図2に示された各トランジスタのQu1,Qu2,Qu3の模式的平面パターン構成は、図15に対応している。
いくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これらの実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。
