Overview

Description

HMC744LC3 is an RF/microwave monolithic mixer IC from Hittite (now Analog Devices). It’s an 8‑lead LCC packaged MMIC that provides frequency conversion by mixing RF and LO signals to produce an IF output. The device is used in front‑end modules for up/down conversion in communication and radar systems, and it requires external matching networks and a bias/drive per the datasheet. Typical use cases include receivers and transmitters where frequency translation and image rejection are needed. Exact performance (frequency range, gain, noise figure, third‑order intercept, LO drive, and bias requirements) depends on the chosen matching and operating conditions, so the datasheet should be consulted for specific specs and application recommendations.

Equivalent

I need the device’s function and frequency to give precise cross-references. HMC744LC3 is a Hittite GaAs MMIC; substitutes depend on whether it’s an amplifier, mixer, etc., and the RF band. Please specify the exact function and operating band (e.g., RF amplifier 0.5–2 GHz). I can then provide concrete equivalents from Analog Devices, Mini-Circuits, Skyworks, and M/A-COM.

Pinout

Pin count: 8 pins. Function: Broadband GaAs MMIC mixer (RF/LO/IF ports) in an 8‑pin package.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
Origin: The HMC prefix comes from Hittite Microwave Corporation, a fabless RF/microwave IC design and manufacturing company. Hittite was acquired by Analog Devices in 2014, so the part is now produced by ADI, a global semiconductor company specializing in analog, RF, and microwave ICs and subsystems.

Application

Typical application areas for HMC744LC3 include RF/microwave front-end modules such as mixers and frequency translators used in wireless transceivers, radar, satellite links, and test instrumentation. Suitable for LO–mixer networks, up-conversion/down-conversion stages, and IF processing in communications systems. Also applicable to aerospace/defense RF front-ends and automotive radar where compact, high-frequency MMICs are needed.

Package

Leadless ceramic package (LCC), 3×3 mm.
