The design and thermal measurement of III-V integrated micro-coolers for thermal management of microwave devices
… the dissipated power density. For many microwave devices, for example the planar Gunn diode, standard thermal management may no longer be sufficient to effectively remove the increasing dissipated power. The work has looked at the design and development of an active micro-cooler, which …

High-speed Type-II GaAsSb/InP DHBTs for mixed-signal IC applications
Heterojunction bipolar transistors (HBTs) are widely used in high-speed mixed-signal, radio frequency, and communication ICs because of their high speed, high breakdown voltage, and high efficiency capabilities compared with Si bipolar junction transistors (BJTs) and complementary metal-oxide …
