Abstract : The effect of collector capacitance, both voltage fixed and voltage variable, on the performance of RF transistors is discussed. Two methods for reducing this capacitance are described; (1) the use of integral leads to reduce the fixed bonding pad capacitance and (2) N(+) conductance plugs to reduce depletion layer capacitance by permitting the use of higher resistivity starting material Data are given on the performance of paralleled transistors in a cavity structure, and the problems associated with paralleling of transistors are considered. Power output measurements are given on low and medium power RF transistors connected in a Darlington configuration. The necessary circuit modifications are discussed. (Author)
