Abstract
An electronic switching component (1) with gallium arsenide-based field effect transistors has its own housing (2) with at least one transparent section (3). An electronic microwave circuit (10) has at least one electronic switching component (1) with gallium arsenide-based field effect transistors and its own housing (2) with at least one transparent section (3). The at least one electronic switching component (1) can be illuminated by means of at least one light source (6, 11).
Claims16
Electronic-switching component with gallium-arsenide-based field-effect transistors and a dedicated housing, said dedicated housing providing at least one transparent portion,
- the housing further comprising at least one retaining device accommodating at least one of one end of an optical waveguide and an LED-light source, and a housing compartment having internal light-reflecting walls, wherein the wavelength range of the LED-light source is in the infrared wavelength range,
- the retaining device being unitary with the housing,
- wherein the transparent portion of the housing comprises optical properties corresponding to those of a dispersive lens, and
- wherein the transparent portion is adapted to illuminate a surface of a substrate containing the field-effect transistors via the dispersive lens to generate electron-hole pairs to neutralize charges trapped in surface imperfections of the gallium-arsenide based field-effect transistors to accelerate switching.
