Knowles in Electronic Industries (Philadelphia) Aug. 55 Recent developments at several locations have resulted in a new line of VHF-UHF Transistors... We will refer to this new line of transistors as Mesa Transistors. 1958 C. H. Knowles in Electronic Industries (Philadelphia) Aug. 55 The Mesa Transistor gets its name from its physical configuration... A basic part of its structure is the ‘Mesa’, (Spanish name for ‘table’), which is the active region of the transistor. 1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) VII. 316/1 Silicon mesa diodes are also used for high-speed, low-power applications. 1972 R. Boylestad & L. Nashelsky Electronic Devices & Circuit Theory iii. 137 The diffusion technique is employed in the production of mesa and planar transistors, each of which can be of the diffused or epitaxial type. 1995 Optical & Quantum Electronics 27 553 The mesa type geometry has many advantages such as simplicity of fabrication, low dark current and low capacitance. < as lemmas |
