—This paper discusses high-performance planar suspended inductors for hybrid integration with microwave circuits. The inductors are fabricated using a silicon surface microma-chining foundry process and assembled using flip-chip bonding. The silicon substrate is removed, leaving a metal inductor suspended 60 m above the microwave substrate, thus reducing(More)

This paper presents work towards heterogeneous integration of high-efficiency power amplifiers (PAs) with tuner and biasing circuits implemented with micro-electro-machined elements. The PAs operate in switched mode with over 70% efficiency at X-band. Many such switched-mode amplifiers are used as the active portion of spatial power combining antenna(More)
