Overview
The HMC560ALM3 is a general-purpose, double balanced mixer produced by Analog Devices Inc. This chip is designed to operate as either an upconverter or a downconverter within the frequency range of 22 GHz to 38 GHz. It is fabricated in a compact chip area, making it ideal for various high-frequency applications. The mixer does not require any external components or matching circuitry and operates with local oscillator (LO) drive levels above 9 dBm. It features optimized balun structures, which provide excellent LO to RF and LO to IF suppression.
