Abstract

Analytical models Antenna arrays Circuits Frequency Optical arrays Optical control Performance analysis Phased arrays Power measurement Signal Analysis
The optical control of the distributed electronics in phased array antennas requires specialized circuits which are compatible with the T/R level data mixing architecture. This paper presents an analytical modeling of a novel circuit, a push-pull self-oscillating mixer, that can perform three important functions: 1) oscillation, 2) frequency and phase locking to a reference signal, and 3) mixing with the data signals. The expected and the measured results show that this proposed circuit performs these three functions efficiently in a low power consuming circuit. This concept was analyzed and experimentally demonstrated at 12 GHz by use of a MESFET pair with a measured conversion efficiency as high as 13dB. Efficient subharmonic injection locking was also demonstrated. This design can be easily extended to HEMT and HBT at higher frequencies.
