MDA4-752H+

Overview

The MDA4-752H+ is a wideband double balanced mixer-amplifier from Mini-Circuits, operating within a frequency range of 2.2 GHz to 7.5 GHz. It integrates a mixer die, an LO amplifier die, and an IF amplifier die into a single package. The component utilizes InGaP HBT technology for the mixer and LO amplifier, while employing E-PHEMT technology for the IF amplifier stage. It is housed in a compact 24-QFN (4x4) surface-mount package designed for board mounting. This multi-chip module architecture supports high-performance signal processing in RF and microwave applications.
