Product details
Overview
HMC523LC4 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC I/Q mixer in a 24-lead 4×4 mm SMT package, operating from 15–23 GHz RF/LO and DC–3.5 GHz IF. It functions as an image-reject mixer (IRM) or single-sideband upconverter with 25 dB typical image rejection, +25 dBm input IP3, and 10 dB typical conversion loss at +17 dBm LO drive - deployed in point-to-point radios and military RF front-ends.
For engineers reviewing the HMC523LC4 datasheet, HMC523LC4 pinout, HMC523LC4 application, or HMC523LC4 equivalent, this page delivers verified RF performance data, validated 24-pin terminal mapping, real-world IRM/SSB use cases, and two confirmed alternative mixers for 15–23 GHz systems requiring high image rejection and wide IF bandwidth.
Technical Context
The HMC523LC4 integrates two double-balanced GaAs MESFET mixer cells with an on-die 90° hybrid to generate quadrature IF outputs (IF1/IF2), enabling image rejection without external hybrids. Its RF and LO ports are AC-coupled and 50 Ω matched across 15–23 GHz, while IF ports support DC-coupled operation up to 3.5 GHz.
It operates over −55°C to +85°C with 191.5 °C/W thermal resistance and MSL3 rating. Absolute maximum ratings include +20 dBm RF/IF input, +27 dBm LO drive, and 340 mW continuous dissipation at 85°C - requiring full ground paddle soldering per alumina package specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 15–23 GHz - supports full-band operation in E-band point-to-point links and military SATCOM terminals. |
| IF Bandwidth | DC–3.5 GHz - enables baseband I/Q demodulation and wideband upconversion without external IF hybrids. |
| Image Rejection | 25 dB typical - suppresses unwanted sideband by >300× voltage ratio, critical for high-fidelity IRM architectures. |
| Input IP3 | +25 dBm - maintains linearity under strong interferers in dense RF environments like VSAT hubs. |
| Conversion Loss (IRM) | 10 dB typical at +17 dBm LO - defines signal path gain budget; requires +17 dBm LO source for optimal performance. |
| LO–RF Isolation | 47 dB - minimizes LO leakage into antenna paths, reducing spurious emissions and receiver desensitization. |
| Amplitude & Phase Balance | 0.3 dB / 4° - ensures accurate quadrature generation for <−25 dBc sideband suppression in SSB upconverters. |
Pinout & Package
24-lead 4×4 mm leadless RoHS-compliant SMT package with alumina body, gold-over-nickel plating, and exposed ground paddle requiring soldering to PCB RF ground. Thermal resistance is 191.5 °C/W (junction-to-package bottom).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 6–8, 10, 13, 17–24 | No Connection | Internally unconnected; may be grounded without performance impact - simplifies layout routing. |
| 3, 5, 12, 14, 16 | Ground | RF/DC ground terminals; must connect to PCB ground plane with low-inductance vias for stability. |
| 4 | RF Input/Output | AC-coupled, 50 Ω matched port for 15–23 GHz signals - no external matching required in band. |
| 9 | IF1 Output | DC-coupled I-channel output; sourcing/sinking >3 mA risks failure - requires external DC blocking if not used to DC. |
| 11 | IF2 Output | DC-coupled Q-channel output; identical electrical behavior to IF1 - forms quadrature pair with IF1. |
| 15 | LO Input | AC-coupled, 50 Ω matched port for 15–23 GHz LO drive - optimized for +17 dBm nominal input level. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar I/Q mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP4E | 17–27 GHz RF/LO range; 22 dB image rejection; +22 dBm IP3; 4×4 mm QFN package. | Better high-end frequency coverage but lower image rejection and linearity than HMC523LC4. | Select when extending beyond 23 GHz is required and 3 dB image rejection margin can be accepted. |
| Qorvo QM11024 | 15–23.5 GHz RF/LO; 20 dB image rejection; +20 dBm IP3; 5×5 mm laminate package. | Lower integration (requires external hybrid); larger footprint; reduced thermal performance vs. alumina. | Choose for cost-sensitive production where alumina package robustness is not mandatory. |
Compared with HMC1048LP4E and QM11024, the HMC523LC4 delivers superior image rejection and IP3 within its native 15–23 GHz band, leveraging monolithic GaAs integration and alumina packaging for demanding military and test equipment applications - making it the preferred choice where sideband purity and thermal reliability are critical.

FAQ
What is the recommended LO drive level for optimal performance of the HMC523LC4?
The HMC523LC4 achieves best image rejection and conversion loss at +17 dBm LO drive, with usable range from +11 to +19 dBm. At +17 dBm, typical image rejection reaches 25 dB and conversion loss is 10 dB. Deviating below +15 dBm degrades image rejection; exceeding +19 dBm risks compression or reliability issues. The HMC523LC4 datasheet specifies +17 dBm as the nominal LO level for all key RF specs.
Can the HMC523LC4 operate as both an image-reject mixer and a single-sideband upconverter?
Yes, the HMC523LC4 is explicitly designed for dual-mode operation: as an image-reject mixer (downconversion) and as a single-sideband upconverter (upconversion). Its integrated 90° hybrid and matched I/Q paths enable both functions without external components. The HMC523LC4 functional diagram and "Typical Applications" section confirm use in both IRM and SSB upconverter configurations.
What are the grounding requirements for the HMC523LC4 package?
All GND pins (3, 5, 12, 14, 16) and the exposed ground paddle must be soldered to a solid RF ground plane using multiple low-inductance vias. The package outline drawing specifies that "all ground leads and ground paddle must be soldered to PCB RF ground." Failure to fully ground the paddle increases thermal resistance and degrades RF performance - the HMC523LC4 thermal resistance is rated at 191.5 °C/W only with proper paddle soldering.
Does the HMC523LC4 support DC-coupled IF operation?
Yes, both IF1 (pin 9) and IF2 (pin 11) are DC-coupled ports. However, the HMC523LC4 pin description warns that IF1 must not source or sink more than 3 mA DC current - exceeding this causes non-function or permanent damage. For AC-only IF use, external DC blocking capacitors are recommended; for true DC–3.5 GHz operation, bias networks must limit current to ≤3 mA.
What is the absolute maximum RF/IF input power rating for the HMC523LC4?
The HMC523LC4 absolute maximum RF/IF input power is +20 dBm, as stated in the "Absolute Maximum Ratings" table. This limit applies to both RF (pin 4) and IF ports (pins 9 and 11). Exceeding +20 dBm risks gate oxide damage or metallization failure. The HMC523LC4 evaluation PCB design guidelines reinforce this by specifying K/SMA connectors rated for ≤+20 dBm - consistent with the device's safe operating area.
