A 94-GHz 16-element phased array transmitter IC in a 130 nm BiCMOS technology is reported. The IC integrates 16 transmitter front ends with two independent outputs, a 1-to-16 power splitter, an IF-to-RF up-converter, a frequency synthesizer with continuous lock detection, an IF/baseband, and digital circuitry including serial interface and front-end memory within an IC size of 6.7 mm × 5.6 mm. A milimeter-wave...
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....
