Abstract
約8〜10GHz以上の高周波信号により発光素子モジュールを駆動する際、入力信号に生じるひずみを低減して出力光波形の改善をはかった光送信機を提供することにある。
【解決手段】
本発明は、回路基板(フレキシブル基板も含む)4に信号配線パターン7及びGND導体パターン6によりマイクロストリップ線路を形成し、発光素子モジュール1の信号リード2を前記信号配線パターンに接続される信号リード実装穴5に実装して前記信号配線パターンに接続して構成される光送信機であって、前記回路基板上の前記信号配線パターン7に、前記発光素子モジュールのステム10との間に容量を付加するパターン8を設けたことを特徴とする。また、前記回路基板上の前記信号配線パターンと発光素子モジュールのステムとの間の付加容量を用いて、線路を形成したことを特徴とする。
