概要

Description

HMC345LP3 is a GaAs MMIC mixer from Analog Devices (formerly Hittite), provided in an LP3 3x3 mm plastic package. It is a compact, 50-ohm matched mixer that can perform RF/LO/IF frequency conversion (up/down conversion) for microwave front-ends. Suitable for wideband applications such as communications, radar, and test instrumentation. The device requires appropriate LO drive and external matching networks (and biasing if needed). It’s typically used with evaluation boards and reference designs to implement upconverter or downconverter stages. For exact frequency range, conversion loss/ISOL, LO drive, and power requirements, refer to the HMC345LP3 datasheet and evaluation kit docs.

Features

Here are the typical features you’d expect for HMC345LP3 (Analog Devices/Hittite MMIC mixer) in concise form:
- GaAs MMIC mixer in a small LP3 plastic package
- 50 Ω matched RF, LO, and IF ports; typically single-ended inputs
- Wide broadband mixing capability (covers several hundred MHz to a few GHz)
- Moderate LO drive requirement (low to mid single-digit dBm)
- Low conversion loss with good port-to-port isolation
- Compact, reusable packaging suitable for surface-mount designs
- RoHS-compliant; suitable for industrial temperature ranges (often -40°C to +85°C)
- Designed for use in downconverters/upconverters and wideband RF/microwave front-ends
Note: exact RF/LO/IF frequency ranges, conversion loss, isolation, and LO drive specs depend on the specific lot and operating conditions. For precise values, please refer to the official datasheet.

Package

The HMC345LP3 uses Hittite’s LP‑3 leadless surface‑mount package — a compact, RoHS‑compliant leadless SMT package with an exposed ground paddle for PCB mounting and thermal/grounding. Exact dimensions and pad layout are in the datasheet.

Manufacturer

The HMC345LP3 is manufactured by Analog Devices, Inc. (originally Hittite Microwave Corporation). Analog Devices is a multinational semiconductor company that designs and manufactures high-performance analog, mixed-signal, RF and microwave integrated circuits and components for communications, industrial, aerospace/defense and instrumentation markets.

Application

HMC345LP3 is a broadband RF/microwave mixer used in front-end modules. Applications: downconversion and upconversion in wireless receivers and transmitters; LO/RF/IF signal translation; radar, SATCOM, and point-to-point links; and test/measurement equipment in cellular, Wi‑Fi/WiMAX, and other microwave systems.

Equivalent

There is no single guaranteed drop‑in equivalent to the HMC345LP3. To find substitutes, match frequency range, gain, noise figure, P1dB, bias and package. Typical alternate sources: other Analog Devices/HMC series parts, Qorvo MMIC amplifiers, and Mini‑Circuits gain blocks. Tell me the required frequency band and key specs (gain, NF, P1dB, supply/bias, package) and I’ll list the closest direct equivalents.
