Figure 340 Designing a T network for use between a resistive source and load
9 The circuit is shown completed in Fig 341 Other possible circuit configurations can be used as required (Fig 342) Figure 342a, b, and c are combined as in step 8 above, but the signs must be maintained for b and c because of the opposite reactance employed ( for inductors and for capacitors) Wideband matching Sometimes it may be necessary to design a lowQ, very
wideband matching network This can be done as follows, by using Fig 343a for a pure resistive load that is smaller than the pure resistive source or by employing Fig 343b for a pure resistive load that is larger than the pure resistive source XS1 and XP1 can be considered as a separate L network from XS2 and XP2, so each L may be oriented any way that is convenient For instance, XS1 may be an inductor, so XP1 must then be a capacitor; however, XS2 may be the capacitor, with XP2 being the inductor: 1 Solve for R : "R" 2 Solve for loaded Q: Q 3 Complete for Fig 343a: XP2 "R" Q2 Q2 "R" RL 1 397 ohms (Q2 219) XS2 XP1 RS Q1 Q1 RS "R" 1 229 ohms (Q1 XS1 Q2RL and 328 ohms and 1896 ohms "R" RSMALLER 1 22 RS RL 87 ohms 218) Q1"R" Downloaded from Digital Engineering Library @ McGrawHill (wwwdigitalengineeringlibrarycom) Copyright 2004 The McGrawHill Companies All rights reserved Any use is subject to the Terms of Use as given at the website Amplifier Design
