Broadband Monolithic Digital Attenuator for X-Band Phased Array

Broadband Monolithic Digital Attenuator for X-Band Phased Array

In this paper the design and performance of an integrated circuit for broadband 5-bit monolithic microwave (MMIC) digital attenuators are presented. Extensive electromagnetic simulation and compact circuit design techniques have been applied in order to yield MMIC with 2.1times1.6times0.125 mm 3 dim...

Zusammenfassung:In this paper the design and performance of an integrated circuit for broadband 5-bit monolithic microwave (MMIC) digital attenuators are presented. Extensive electromagnetic simulation and compact circuit design techniques have been applied in order to yield MMIC with 2.1times1.6times0.125 mm 3 dimensions. MESFET have been used as key elements. Performance of the digital attenuator measured at 6-12 GHz demonstrates 8-11 dB insertion loss
