Abstract :
A constant time delay over temperature for miniaturized microstrip delay lines on high permittivity substrates is of great importance for many applications, particularly for space systems. A simple design formula helpful for the selection of a highly temperature stable substrate is presented. Moreover, a 274 ps delay line on CB substrate with a 0.40% variation in time delay over the temperature range of -52/spl deg/C to +50/spl deg/C has been developed.
