Patent ID: 6900696

Claim:
Electronic apparatus ( 10 , 20 , 26 , 30 , 38 , 48 , 66 , 70 , 82 , 90 , 96 , 100 , 108 , 118 , or 122 ) which comprises: a solid-state electronic device (Q 1 , Q 3 , or Q 5 ) that includes higher and lower dc voltage terminals; an other electronic device (Q 2 , Q 4 , Q 6 , Q 7 , Q 8 , 92 , 110 , 112 , Q 11 , or Q 12 ) that includes higher and lower dc voltage terminals; means, comprising means (L 2 ) for connecting said lower dc voltage terminal of one of said electronic devices to said higher dc voltage terminal of an other of said electronic devices, for connecting said electronic devices in dc series between a dc source terminal and an electrical ground; means, comprising a capacitor (C 5 , C 6 , or C 19 ) that is connected between said lower dc voltage terminal of said one electronic device and said electrical ground, for rf decoupling said dc series-connected electronic devices; and said means for if decoupling further comprises means ( 86 ) for making an effective series resistance, between said lower dc voltage terminal of said one electronic device and said electrical ground, lower than a porcelain capacitor that resonates at an rf frequency of said one electronic device.
