摘要

Three HBT monolithic microwave integrated circuit (MMIC) designs from the basis of a complete digital oscilloscope front-end which has been designed, fabricated and tested. Theses devices are integrated into a thick-film hybrid which is currently being used as the front-end for a digital sampling oscilloscope (DSO). The three devices are based on a closed loop differential amplifier with a gain of 10 dB and a bandwidth greater than 6 GHz.
