A high frequency electronic package (500) having a metal housing (504) and a high frequency electronic component, such as a laser diode, contained within the metal housing (504). One or more leads (508, 510, 512, 514) pass into the metal housing through a header (506) and are coupled to the high frequency electronic component. The leads, metal housing and components within the housing cause stray inductances and capacitances, which cause problems in matching and driving the high frequency electronic component. Therefore a high value capacitor (502) is coupled between the metal housing and an anode lead, as close to the anode as possible, to short the stray capacitances at high frequencies. The capacitor can be a ring capacitor positioned over the anode lead externally of the housing, or can be a plate capacitor mounted internally or externally of the housing.
