Inphi Corp. announced three new differential amplifiers 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 include the 1010DA (DC to 9GHz) and 1011DA (DC to 10GHz) differential amplifiers and the 1012VA (DC to 10GHz) differential variable gain amplifier.

The 1010DA, 1011DA and 1012VA are all true DC to 10GHz (3dB) 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 26dB and maximum differential output amplitude of 2Vpp; the 1011DA a gain of 32dB and maximum differential output amplitude of 4Vpp; and the 1012VA has a maximum differential gain of 27dB, dynamic range of better than 14dB and maximum differential output amplitude of 2Vpp.

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. All of the parts include differential input and output as well as input common mode ranges of 500mV. The 1010DA and the 1012VA feature gain flatness of 0.5dB to 3.5GHz; an input return loss of 20dB to 5GHz; up to 2Vpp differential output; and an output return loss ranging from 15dB to 5GHz.

The 1010DA and the 1012VA are available immediately in QFP packages. The 1011DA will be available in Q1 of 2006. Initial pricing is expected to be $299 per part in small quantities.
