Overview
The HMC557ALC4TR is a general-purpose, double-balanced mixer produced by Analog Devices Inc. This device is designed for use in a wide range of RF applications and is fabricated in a gallium arsenide (GaAs) metal semiconductor field effect transistor (MESFET) process. It is housed in a 24-terminal, ceramic leadless chip carrier (LCC) package, which is RoHS-compliant and compatible with high-volume surface-mount manufacturing techniques. The mixer can be used as either an upconverter or downconverter, operating within the frequency range of 2.5 GHz to 7.0 GHz.
