M/A-COM Announces New GaAs Beam Lead Schottky Barrier Diodes; Low-Cost Diode Family For Use at Millimeter Wave Frequencies.BURLINGTON, Mass.--(BUSINESS WIRE)--Sept. 28, 1998--M/A-COM, a division of AMP Incorporated and the leading global provider of wireless radio frequency (RF), microwave and millimeter wave components, today announced a new family of GaAs Beam Lead Schottky Barrier Diodes. The new family features diodes with a high cut-off cut-off Anesthesiology The point at which elongation of the carbon chain of the 1-alkanol family of anesthetics results in a precipitous drop in the anesthetic potential of these agents–eg, at > 12 carbons in length, there is little anesthetic activity, frequency, allowing use through low millimeter wave frequencies. The MA4E2037 single, MA4E2039 anti-parallel pair and MA4E2040 series tee Schottky diodes are fabricated on OMCVD OMCVD Organo-Metallic Chemical Vapor Deposition epitaxial wafers using a process developed for high device uniformity and low parasitics. The use of a low dielectric constant dielectric constant n. See permittivity. polymer prevents scratches and other damage to the airbridge during handling, without significantly increasing device parasitics. The use of an airbridge anode anode (ăn`ōd), electrode through which current enters an electric device. In electrolysis, it is the positive electrode in the electrolytic cell. anode Terminal or electrode from which electrons leave a system. contact in the new diodes will give the customer improved uniformity of electrical characteristics, which will improve isolation and impedance matching Impedance matching The use of electric circuits and devices to establish the condition in which the impedance of a load is equal to the internal impedance of the source. in balanced mixer or modulator Modulator Any device or circuit by means of which a desired signal is impressed upon a higher-frequency periodic wave known as a carrier. The process is called modulation. The modulator may vary the amplitude, frequency, or phase of the carrier. circuits. This new family of GaAs Beam Lead Diodes was designed to replace the MA40415, MA40416 and MA40422 diodes. The new diodes have better electrical and mechanical characteristics, and have better uniformity from device to device. "This new family of diodes offers our customers an array of devices for millimeter wave applications. They can be used in single and double balanced mixers in transceivers for point-to-point (PTP (1) See peer-to-peer. (2) (Picture Transfer Protocol) An ISO standard for transferring photos from a digital camera to a computer or photo printer. ) radios, automotive radar systems and police radar detectors," said John Putnam, Senior Principal Engineer, Semiconductor Business, M/A-COM. "In addition, we can offer this new family of GaAs Beam Lead Schottky Barrier Diodes at a low price point." The MA4E2039 anti-parallel pair was specifically developed for subharmonically pumped mixers; close matching of the diode characteristics yields a high LO suppression at the RF input. Availability The MA4E2037 single, MA4E2039 anti-parallel pair and MA4E2040 series tee diode are all immediately available through M/A-COM's direct sales channel in the US, as well as its international sales channel.
