Abstract
Microcircuit chip packages mounted modules are connected together by lossy strip transmission lines parallel to a ground plane without termination. The transmission line segments are designed to have a total resistance R.sub.L which is within the range between two-thirds and two times the characteristic impedance Z.sub.o of the transmission line. Reflections are prevented from causing signal problems by maintaining R.sub.L above the minimum value. Similarly, the maximum value is intended to prevent deterioration of the wave shape.
