MAX2680 - SiGe Downconverter Mixers

General Description

The MAX2680/MAX2681/MAX2682 miniature, low-cost, low-noise downconverter mixers are designed for lowvoltage operation and are ideal for use in portable communications equipment.

Signals at the RF input port are mixed with signals at the local oscillator (LO) port using a double-balanced mixer.
