A 94GHz phased array receiver IC in 130nm BiCMOS technology is reported. The design integrates 32 front ends with gain and phase control configurable using look-up table memory, two separate 16∶1 power combiner trees, two 94GHz to ∼10GHz (IF) down conversion mixers, an IF to baseband (BB) quadrature down conversion mixer, and a 42GHz PLL followed by a frequency doubler implementing the LO source....
This paper discusses the design and implementation of a 94-GHz phased-array transceiver front-end in SiGe BiCMOS that is capable of receiving concurrently in both vertical (V) and horizontal (H) polarizations and time-duplexed transmission in either polarization. The compact front-end is implemented in of silicon area to ensure compatibility with a scalable phased-array...
This paper presents a multi-function, dual-polarization phased array transceiver supporting both radar and communication applications at W-band. 32 receive elements and 16 transmit elements with dual outputs are integrated to support 16 dual polarized antennas in a package. The IC further includes two independent 16:1 combining networks, two receiver downconversion chains, an up-conversion chain,...
A 0.12-μm SiGe phased-array Rx IC for beam-steered wireless communication in the 60-GHz band is described. It has 16 RF phase-shifting front-ends with 11° digital phase resolution and hybrid passive-active RF signal combining. It achieves 7.4-7.9 dB NF (not including 12-dB array gain) over the 4 IEEE channels. The IC has a double-conversion superheterodyne Rx core with a maximum of 72 dB of power...
