Fully Integrated Frequency and Phase Generation for a 6-18GHz Tunable Multi-Band Phased-Array Receiver in CMOS
نویسندگان
چکیده
Fully integrated frequency-phase generators for a 6-18GHz wide-band phased-array receiver element are presented that generate 5-7GHz and 9-12GHz first LO signals with less than -95dBc/Hz phase noise at 100kHz offset. Second LO signals with digitally controllable fourquadrant phaseand amplitude spread with better than 3 resolution are generated and allow removal of systematic reference clock skew as well as accurate selection of the received signal phase. This frequencyand phase generation scheme was successfully demonstrated in a 6-18GHz receiver system configured as an electrical 4-element array.

A New Analog-based LO Harmonic Rejection Technique with Tunable Notch Frequency
An effective technique for mixer LO harmonic rejection in a SAW-less wideband receiver front-end is proposed. The proposed technique provides a tunable notch that can be placed at any frequency like mixer LO harmonics, to avoid the aliasing in baseband after mixing. An analog LC notch is used in a cascode transconductor, and it can reject one of the 3rd or 5th harmonics. T...
متن کاملPhased array antenna using MEMS phase shifter
This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...

متن کاملAn 8-18GHz 0.18W Wideband Recursive Receiver MMIC with Gain-Reuse
This paper presents an 8-18GHz wideband receiver with superheterodyne topology. In order to save power, both RF and IF signals share the tunable transconductance stage. The IF output of the first mixer is fed to its tunable input stage for IF amplification in a recursive manner, which significantly enhances the gain tuning without increasing the power. The wideband receiver MMIC is implemented ...
