ABSTRACT:
A variable feedback and tuning capacitor, which is fabricated from a brac with bendable metallic prongs, is attached to the input transmission line of a microwave transistor amplifier. The prongs are placed in close proximity to the collector pad metalization of the carrier and provide a convenient and novel means for RF tuning the amplifier after the transistor is carrier mounted and DC tested.
