Analog Devices Inc. HMC8192

Overview

HMC8192 from Analog Devices is a passive wideband I/Q MMIC mixer operating from 20–42 GHz RF/LO and DC–5 GHz IF, delivering −8.5 dB conversion loss, +22 dBm IIP3, and 25 dB image rejection; it serves as an image-reject downconverter or single-sideband upconverter in high-frequency test instrumentation and radar front-ends.

For engineers reviewing the HMC8192 datasheet, HMC8192 pinout, HMC8192 application, or HMC8192 equivalent, key selection criteria include its GaAs MESFET-based passive architecture, 4 mm × 4 mm 25-lead LGA package, −40°C to +85°C operation, LO drive requirement of +15 to +22 dBm, and elimination of IF filtering due to inherent image rejection.

Technical Context

The HMC8192 implements a monolithic 90-degree hybrid-coupled I/Q architecture using Analog Devices' proprietary GaAs MESFET mixer cells, enabling simultaneous image-reject downconversion and single-sideband upconversion without external phase-shifting networks.

Its passive design eliminates DC power requirements and delivers lower noise figure versus active mixers, while the integrated RF/LO/IF 50 Ω dc-coupled interfaces support broadband operation across millimeter-wave bands with no external biasing or matching components needed beyond evaluation board layout.

Key Specifications

Pinout & Package

The HMC8192 is housed in a compact 4 mm × 4 mm, 25-lead Land Grid Array (LGA) package with exposed die bottom for thermal management and RF grounding. All ground pins (1–8, 10, 12–15, 17–23, 25) must be soldered to RF/dc ground plane; RF and LO ports are dc-coupled 50 Ω inputs; IF1/IF2 are differential dc-coupled outputs.

FAQ

What is the recommended LO drive level for optimal performance of the HMC8192?

The HMC8192 requires an LO drive level between +15 dBm and +22 dBm for specified performance; +18 dBm is the typical condition used in datasheet characterization. Operating below +15 dBm increases conversion loss and degrades IIP3, while exceeding +22 dBm risks reliability degradation. The HMC8192 datasheet specifies absolute maximum LO power as TBD, but sustained operation above +22 dBm is not recommended. Always verify LO drive with calibrated source when integrating the HMC8192 into final design.

Does the HMC8192 require DC power to operate?

No, the HMC8192 is a passive mixer fabricated using GaAs MESFET technology and contains no active transistors requiring bias. It operates without any DC power supply, eliminating quiescent current, thermal management overhead, and associated noise contributions. This passive nature directly contributes to its lower noise figure compared to active mixers and makes the HMC8192 ideal for power-constrained or thermally sensitive applications such as airborne radar modules and portable test equipment.

Can the HMC8192 be used for both upconversion and downconversion?

Yes, the HMC8192 supports both modes: as an image-reject downconverter (RF → IF) and as a single-sideband upconverter (IF → RF). Its symmetric I/Q architecture allows bidirectional signal flow. In upconversion mode, the IF1/IF2 ports serve as inputs, RF as output, and LO remains the local oscillator input. Performance parameters-including conversion loss, image rejection, and isolation-are characterized and validated for both configurations per the HMC8192 datasheet and evaluation board test reports.

What is the function of Pins 9 and 11 on the HMC8192?

Pins 9 and 11 are the differential IF output terminals (IF1 and IF2) in downconversion mode or differential IF inputs in upconversion mode. They are dc-coupled and rated for ±3 mA dc current; exceeding this may cause malfunction or damage. For ac-coupled IF paths, external series capacitors must be selected to pass the full DC–5 GHz IF bandwidth. These pins form one leg of the I/Q pair-the complementary leg is implemented internally via the 90-degree hybrid-and their amplitude and phase balance directly determine image rejection performance.

Is an evaluation board available for the HMC8192, and what does it include?

Yes, an official evaluation board is available for the HMC8192. It is fabricated on Rogers® RO4003C laminate, includes optimized 50 Ω RF/LO/IF microstrip routing, dc-blocking and biasing provisions, and edge-mount SMA connectors for all ports. The board supports both downconversion and upconversion configurations and ships with schematic (Figure 16), top-layer (Figure 17), and bottom-layer (Figure 18) documentation. Evaluation board ordering information and Gerber files are accessible via Analog Devices' website under HMC8192 product page resources.
