Inphi Corporation's New DC to 9 and 10 GHz Differential Amplifiers Deliver the Industry's Highest Bandwidth and Best Linearity.WESTLAKE VILLAGE, Calif. -- New Devices from Inphi Are the Industry's Only True DC to 10 GHz (3 dB) Amplifiers with Exceptional Linearity, Gain Flatness and Large Output Amplitude amplitude (ăm`plĭt  d'), in physics, maximum displacement from a zero value or rest position. Setting new performance standards that directly meet customer needs in the high-performance telecommunications and test and measurement markets, Inphi Corporation (www.inphi-corp.com) today announced three new Differential Amplifiers Differential amplifier An electronic circuit that is designed to amplify the difference between two voltages measured with respect to a common reference, usually designated as ground. developed specifically to meet the challenges encountered in designing broadband test and measurement equipment, automatic test equipment (ATE), and a wide range of aerospace and military applications. The new products are the 1010DA: DC to 9 GHz, 1011DA: DC to 10 GHz Differential Amplifiers and the 1012VA: DC to 10 GHz Differential Variable Gain Amplifier. "These parts meet a critical design need that has never been addressed by other solutions," said Kevin Nary nar·y adj. Not one: "Frequently, measures of major import . . . glide through these chambers with nary a whisper of debate" George B. Merry. , vice president of engineering for Inphi Corporation. "We hear directly from our customers that Inphi's differential amplifiers clearly meet critical design needs in terms of bandwidth, linearity, and performance. We believe these solutions are another example of Inphi's commitment to setting industry standards in integrated circuit integrated circuit (IC), electronic circuit built on a semiconductor substrate, usually one of single-crystal silicon. The circuit, often called a chip, is packaged in a hermetically sealed case or a nonhermetic plastic capsule, with leads extending from it for performance." Inphi's innovative differential amplifiers are being embraced by engineers working with broadband, linear applications, including arbitrary waveform The shape of a signal. See wavelength, sine wave and square wave. generation, high-speed single-ended to differential converters, and post amplifiers for digital-to-analog converters See D/A converter. . The 1010DA, 1011DA, and 1012VA are all true DC to 10 GHz (3 dB) amplifiers with superior linearity, gain flatness, and return loss, which are well suited for applications where a linearly amplified, broadband, differential, or single-ended signal is required. The 1010DA has a gain of 26 dB and maximum differential output amplitude of 2 Vpp; the 1011DA, a gain of 32 dB and maximum differential output amplitude of 4 Vpp; and the 1012VA has a maximum differential gain of 27 dB, dynamic range of greater than 14 dB, and maximum differential output amplitude of 2 Vpp. The wide bandwidth of these parts allows designers to use a single part for multiple applications or design one piece of equipment to cover a wide frequency range, resulting in lower development costs and products with a relatively small footprint. The exceptional linearity of the parts ensures that the output is a true representation of the input, resulting in less than 1% total harmonic distortion The total harmonic distortion, or THD, of a signal is a measurement of the harmonic distortion present and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental. . In addition, the high gain enables a low-level, single-ended, or differential input, while providing a 2-to-4-volt differential output. All of the new parts include differential input and output as well as input common mode ranges of +/- 500 mV. The 1010DA and the 1012VA feature gain flatness of +/- 0.5 dB to 3.5 GHz, an input return loss of 20 dB to 5 GHz, up to 2 Vpp differential output, and an output return loss ranging from 15 dB to 5 GHz. The 1010DA and the 1012VA are available in QFP (Quad FlatPack) A square, surface mount chip package that has leads on all four sides and comes in several varieties. PQFP (Plastic QFP) may refer to all of the following QFP types. All quad flatpacks use gull-wing leads, except for the CQFP, which stick straight out. packages. Availability Inphi Corporation's 1010DA and 1012VA parts are available immediately. The 1011DA will be available in Q1 of 2006. Initial pricing is expected to be $299.00 per part in small quantities. Volume discounts are available. About Inphi Corporation Inphi Corporation is a privately held electro-optical components company based in Westlake Village.
