Analog Devices Inc. HMC560ALM3TR

Overview

HMC560ALM3TR from Analog Devices is a GaAs MMIC double-balanced mixer operating from 22 GHz to 38 GHz, supporting both upconversion and downconversion with no DC bias required. It delivers 10–11 dB typical conversion loss, >34 dB LO-to-RF isolation, and dc–18 GHz IF bandwidth-enabling high-frequency signal translation in millimeter-wave radios and test instrumentation.

For engineers reviewing the HMC560ALM3TR datasheet, HMC560ALM3TR pinout, HMC560ALM3TR application, or HMC560ALM3TR equivalent, this page provides verified RF performance data, terminal-level interface guidance, thermal and isolation behavior across temperature and LO drive, and validated alternatives for mmWave system design.

Technical Context

The HMC560ALM3TR implements a passive, double-balanced architecture using optimized on-die baluns to achieve high LO-to-RF and LO-to-IF suppression without external matching components. Its operation requires ≥9 dBm LO drive and supports upper- or lower-sideband selection in both upconverter and downconverter modes.

It operates over −40°C to +85°C with a CE-6-3 LGA_CAV package (5.08 mm × 5.08 mm), featuring an exposed ground pad for thermal and RF grounding. All ports-RF, LO, and IF-are impedance-matched to 50 Ω, with RF and LO ac-coupled and IF dc-coupled (max ±2 mA).

Key Specifications

Pinout & Package

The HMC560ALM3TR uses a 6-terminal Chip Array Small Outline No Lead Cavity (LGA_CAV) package, designated CE-6-3, with 5.08 mm × 5.08 mm body and 1.01 mm height. The exposed pad must be soldered to RF/dc ground for thermal dissipation and signal integrity.

FAQ

What is the recommended LO drive level for optimal performance of the HMC560ALM3TR?

The HMC560ALM3TR operates reliably with LO drive levels ≥9 dBm, and datasheet characterization is performed at 13 dBm. At 13 dBm, it achieves 10–11 dB typical conversion loss and maximizes LO-to-RF isolation (34–38 dB). Lower LO power increases conversion loss and degrades IP3; exceeding 23 dBm risks permanent damage per absolute maximum ratings.

Does the HMC560ALM3TR require external biasing or matching components?

No. The HMC560ALM3TR is a fully passive double-balanced mixer with internal 50 Ω matching on RF and LO ports and no DC bias requirement. External components are unnecessary for basic operation. Only the IF port may need an external series capacitor if dc blocking is required-otherwise, it must remain dc-coupled with current limited to ±2 mA.

Can the HMC560ALM3TR be used for both upconversion and downconversion?

Yes. The HMC560ALM3TR supports bidirectional operation: as a downconverter (RF 22–38 GHz → IF dc–18 GHz) and as an upconverter (IF dc–18 GHz → RF 22–38 GHz). Performance metrics-including conversion loss, IP3, and isolation-are specified for both modes in the datasheet, with sideband selection determined by LO–RF spacing.

What is the thermal resistance and grounding requirement for the HMC560ALM3TR?

The HMC560ALM3TR has θJC = 188°C/W and requires its exposed pad to be soldered directly to a solid RF/dc ground plane. This connection is mandatory-not optional-for thermal dissipation (max channel temperature 150°C) and RF return path integrity. Inadequate grounding causes gain instability, increased noise figure, and potential die failure under sustained operation.

How does the HMC560ALM3TR perform across temperature and frequency bands?

Over −40°C to +85°C, HMC560ALM3TR maintains stable conversion loss (±0.5 dB variation), IP3 (±0.8 dB), and isolation (±2 dB) within each band. From 22–29 GHz, conversion loss is 10 dB typ.; from 29–38 GHz, it rises to 11 dB typ. Noise figure increases from 10.5 dB to 11.5 dB across the band, consistent with GaAs mixer physics.
