Enhanced air core transmission lines and transformers are disclosed. A transmission line or transformer is disposed on a dielectric substrate, with a first planar conductor on the dielectric substrate and a second planar conductor suspended above the first planar conductor. A set of support posts suspends the second planar conductor above the first planar conductor. Thermal performance of the transmission line or transformer is improved by having each of the set of support posts include a width which exceeds any gap between support posts. In some examples, openings are formed in the second planar conductor and may facilitate etching or other processes of forming the transmission line or transformer.

Enhanced air core transmission lines and transformers

A heterojunction bipolar transistor (HBT) device and system having electrostatic discharge ruggedness, and methods for making the same, are disclosed. An HBT device having electrostatic discharge ruggedness may include one or more emitter fingers including an emitter layer, a transition layer formed over the emitter layer, and an emitter cap layer formed over the transition layer.
