This paper presents the design of an integrated phase shifting frequency synthesizer for active electronically scanned arrays. The proposed frequency synthesizer, implements a 3-channel beam steering unit based on a local oscillator (LO) phase shifting approach that relies on the joint use of external loop filters and voltage-controlled oscillators. The design has been fabricated using AMS 0.35-μm SiGe BiCMOS process and it takes a die area of 9.38-mm2. Based on a frequency independent architecture and targeting space and weight constrained applications, the integrated circuit (IC) allows to program, its output channels, with a 10-bit precision 0° to 360° mutual phase shifts.

Abstract

This paper presents the design of an integrated phase shifting frequency synthesizer for active electronically scanned arrays. The proposed frequency synthesizer, implements a 3-channel beam steering unit based on a local oscillator (LO) phase shifting approach that relies on the joint use of external loop filters and voltage-controlled oscillators. The design has been fabricated using AMS 0.35-μm SiGe BiCMOS process and it takes a die area of 9.38-mm2. Based on a frequency independent architecture and targeting space and weight constrained applications, the integrated circuit (IC) allows to program, its output channels, with a 10-bit precision 0° to 360° mutual phase shifts.
