M A-COM offers high quality varactor series to meet next-generation wireless design needs.BURLINGTON, Mass.--(BUSINESS WIRE)--Oct. 21, 1996-- Debuts first standard varactor varactor: see diode. Varactor A solid-state device which has a capacitance that varies with the voltage applied across it. The name varactor is a contraction of the words variable and reactor. family to deliver high performance at low voltages Low voltage is an electrical engineering term that broadly identifies safety considerations of an electricity supply system based on the voltage used. While different definitions exist for the exact voltage range covered by "low voltage", the most commonly used ones include "mains As a next step in the company's aggressive strategy to build products that enhance next-generation wireless applications, M/A-COM Inc., a global manufacturing leader in wireless products, today announced its first high quality factor (Q)/high capacitance capacitance, in electricity, capability of a body, system, circuit, or device for storing electric charge. Capacitance is expressed as the ratio of stored charge in coulombs to the impressed potential difference in volts. ratio varactor diode family, specifically for wide band tuning and low phase noise applications, and targeted for 3V handheld devices. This new product suite enables applications such as cellular phones, active pagers, and automotive wireless systems to seek the highest quality signal and lock on to the desired frequency. M/A-COM's new standard varactors are particularly suited for voltage control oscillators (VCO's) and voltage tuned filters used in battery operated commercial wireless systems up to 2.5 GHz. The MA4ST200 series typically has Q of 400 at 50 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. and a capacitance ratio of 3.5 from -0.5V to - 4.0V. The new MA4ST200 varactor family are ion-implanted, hyperabrupt junction, silicon tuning varactors allowing for superior capacitance-voltage (C-V C-V Capacitance-Voltage C-V Schedule V Controlled Substance (USA) ) repeatability and permitting ease-of-use to customers. "The MA4ST200 series meets the most crucial needs of today's VCO (1) (Voltage Controlled Oscillator) An oscillator that can be tuned over a wide range of frequencies by applying a voltage (tuning voltage) to it. Used in many applications such as radio tuners, VCOs are less costly than crystal oscillators, but not as stable. designers, who are under greater pressure to provide their customers increasingly complex designs," said Navdeep Arora, M/A-COM's product marketing manager, Wireless Products Division. "This new series provides designers with a best-in-class varactor for broad applications, with the highest Q and capacitance ratio in low voltage applications, an area where most suppliers have been unsuccessful, particularly where noise bandwidth and loss are critical factors. Today's news represents just the first step in an aggressive long-term product development strategy." The MA4ST200 series -- ion-implanted, hyperabrupt junctions, silicon tuning varactors -- are standard off the shelf products supported by short lead times, and aggressively priced for high volume applications, starting at $0.40 at 10K quantities. The MA4ST200 family The ST200 is a family of VLIW processor cores based on technology jointly developed by Hewlett-Packard Laboratories and STMicroelectronics under the name Lx. The main application of the ST200 family is embedded media processing. of varactors feature industry standard, low cost plastic packaging and are available in SOT-23, SOT-323 and SOD-323 profiles, in single and common cathode pair configurations.
