MONOLITHIC COMPATIBILITY AND ABSORBABILITY AMPLITUDE MOLDING NETWORK

摘要

PURPOSE: To provide a compact, light-weight and inexpensive equalizer circuit for microwaves which has the desired performance and capability of an ordinary typical equalizer. CONSTITUTION: This equalizer circuit is provided with a main microstrip transmission line 18 which has an RF input port 19 and an RF output port 20, a horizontal direction microstrip transmission line which is laterally extended from the horizontal direction microstrip transmission line 18 and forms stab tuners 21, 22 and 23 and with a resistance means such as thin film resistances 30, 31 and 32 which are connected to the stab tuners to reduce the Q of these stab tuners and accordingly decide selectively an attenuation profile of the equalizer circuit.
