This paper presents the first 16-element wafer-scale phased array transmitter with scanning in both the E-and H-planes. The chip integrates a 108–112 GHz source, together with a 1∶16 distribution network, amplifiers, 2-bit phase shifters on each cell, and an on-chip high efficiency differential dipole antenna. Measured patterns show scanning to +/−30° in both planes, and agree well with simulations...
This paper presents, for the first time, a low cost, 60 GHz, RF front-end Tx/Rx integrated with a Yagi-Uda antenna array on organic Liquid Crystal Polymer substrate. The Tx/Rx module consists of a GaAs LNA, PA and a Single Pole Double Throw (SPDT) switch wirebonded on a single, multilayer substrate. The array was designed for operation at 60.6 GHz with a gain of 12.1 dBi. The radiation pattern measurements...
A 60-GHz band phased array transmitter is developed based on 90-nm CMOS process featuring compact baseband phase shifters with ideally zero power consumption. The phase shifter changes an RF signal phase every pi/2 by switching baseband signal paths. The transmitter has 6 RF front-ends and 6 phase shifters to implement beam steering function for a 1 times 6 array antenna system. Each of the RF front-ends...
