The 20 nm gate length novel asymmetric GaAs MHEMT also exhibited an ON-state (BVON) and OFF-state (BVOFF) breakdown voltages of 3.1 V and 7.2 V respectively. To the best knowledge of authors, this is the record combination of DC–RF and breakdown performance parameter values ...
RF voltages are applied to the rod body and resistive path, and DC voltages are applied to the resistive path, to create a radially confining RF field and an axial DC field that assists in propelling ions through the multipole interior along the longitudinal axis thereof. In one implementation...
In order to operate a transistor for a certain class, the gate and drain dc voltages have to be biased carefully to the certain operating point (quiescent point or q-point) 1.Class A- q point is about 0.5, it is biased at close to half of its saturated current. Conduction angle is ...

A diverse range of process technologies including GaAs, GaN, SiGe, SOI, and CMOS. That's the difference behind the industry's broadest portfolio of RF ICs, covering the entire RF signal chain from bits to beams, and from DC to beyond 100 GHz. With over 1000 high performance RF ...
RF-sampling ADCs are fabricated using deep submicron CMOS process technology, and the physics of semiconductor devices tells us that smaller transistor geometries support lower maximum voltages. Hence, the data sheet specifies the absolute maximum voltages that should not be exceeded due to reliability ...
corresponding microstrip conductor structures and circuitry of a replaceable module, by establishing a stripline structure for connecting microstrip structures. The RF and DC voltages are thus transitioned in matched fashion from microstrip to stripline (pursuant to the connector) and back to microstrip ...
