Abstract
In this paper the results of miniature thick film resistors designed as add-on lumped resistors are presented. A few resistor configurations have been elaborated and tested, and a specific trimming resistance, which avoids parasitic trimming inductance was used. Some of the designed resistors were used in isolators and directional couplers for the 2-11 GHz band. The electrical parameters have been presented and discussed. The assembly methods for these resistors to the microstrip lines have also been given.
