Description
The IAM-82028 is a complete moderate-power double-balanced active mixer housed in a miniature ceramic hermetic surface mount package. It is designed for narrow or wide bandwidth commercial, industrial and military applications having RF inputs up to 5 GHz and IF outputs from DC to 2 GHz. Operation at RF and LO frequencies less than 50 MHz can be achieved using optional external capacitors to ground. The IAM-82028 is particularly well suited for applications that require load-insensitive conversion gain and good spurious signal suppression and moderate dynamic range with minimum LO power. Typical applications include frequency

downconversion, modulation, demodulation and phase detection for fiber-optic, GPS satellite navigation, mobile radio, and communications receivers.
The IAM series of Gilbert multiplier-based frequency converters is fabricated using
HP’s 10 GHz fT, 25 GHz fMAX ISOSATTM-I silicon bipolar process
which uses nitride self-alignment, submicrometer lithography, trench isolation, ion implantation, gold metallization and polyimide inter-metal dielectric and scratch protection to achieve excellent performance, uniformity and reliability.
