Description
Hewlett-Packard’s INA-50311 is a Silicon monolithic amplifier that offers excellent gain and noise figure for applications to 1.0 GHz. Packaged in a miniature SOT-143 package, it requires very little board space.
The INA-50311 uses a topology which is internally biased, eliminating the need for external components and providing decreased sensitivity to ground inductance.
The INA-50311 is fabricated using
HP’s 30 GHz fMAX ISOSATTM Silicon bipolar process which
uses nitride self-alignment submicrometer lithography, trench isolation, ion implantation, gold metallization, and polyimide intermetal dielectric and scratch protection to achieve superior performance, uniformity, and reliability.
