IAM-81028
Features
* 8 dB RF-IF Conversion Gain From 0.05 - 5 GHz * IF Output from DC to 1 GHz * Low Power Dissipation: 60 mW at VCC = 5 V Typ. * Single Polarity Bias Supply: VCC = 4 to 8 V * Load-Insensitive Performance * Conversion Gain Flat Over Temperature * Low LO Power Requirements: -5 dBm Typical * Low RF to IF Feedthrough, Low LO Leakage * Hermetic Ceramic Surface Mount Package
Description
The IAM-81028 is a complete lowpower-consumption doublebalanced 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 1 GHz. Operation at RF and LO frequencies less than 50 MHz can be achieved using optional external capacitors to ground. The IAM-81028 is particularly well suited for applications that require load-insensitive conversion gain and good spurious signal suppression with minimum LO and bias power consumption. Typical applications include frequency down conversion,

modulation, demodulation and phase detection for fiber-optic, GPS satellite navigation, mobile radio, and battery powered 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. This process 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.
