Product details
Overview
HMC144LH5TR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer operating from 6 to 20 GHz, designed for RF upconversion and downconversion in high-frequency signal chains. It delivers 9–13 dB typical conversion loss, +24 dBm input IP3, 35 dB LO/RF isolation, and DC–3 GHz IF bandwidth with no external bias or passive components required.
For engineers reviewing the HMC144LH5TR datasheet, HMC144LH5TR pinout, HMC144LH5TR application, or HMC144LH5TR equivalent, this device is selected for broadband RF front-ends where hermetic reliability, consistent intermodulation performance across production lots, and surface-mount manufacturability are critical - especially in military radar, space transceivers, and test instrumentation.
Technical Context
The HMC144LH5TR integrates on-chip baluns enabling true double-balanced operation without external hybrids or transformers. Its monolithic GaAs architecture eliminates bond-wire sensitivity and supports stable performance from –40°C to +85°C ambient.
It operates as a passive mixer requiring +13 to +20 dBm LO drive, with RF and LO ports AC-coupled and impedance-matched to 50 Ω, while the IF port is DC-coupled and rated for ±2 mA DC current - enabling true DC–3 GHz baseband support when properly biased.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range (RF/LO) | 6–20 GHz - covers X-band and Ku-band radar, satellite uplinks, and wideband test equipment. |
| IF Bandwidth | DC to 3 GHz - supports direct-conversion receivers and complex baseband I/Q processing without external blocking capacitors. |
| Conversion Loss | 9.5–13 dB typ - defines RF-to-IF signal attenuation; impacts system noise figure and gain budget planning. |
| Input IP3 | +24 dBm - determines third-order intermodulation headroom in multi-carrier or dense-spectrum environments. |
| LO/RF Isolation | 23–35 dB - suppresses LO leakage into antenna paths, reducing spurious emissions and receiver desensitization. |
| Operating Temp | –40°C to +85°C - qualified for extended industrial and military platforms without derating. |
| Package | Hermetic SMT leadless ceramic (25 mm²) - enables reflow assembly and meets MIL-PRF-38535 Class B/S screening requirements. |
Pinout & Package
Package: RoHS-compliant hermetic SMT leadless ceramic package (25 mm²), with gold-plated Kovar/ceramic body and exposed ground paddle requiring solder connection to PCB RF ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 6, 7, 9–12 | GND | All pins plus exposed paddle must be low-inductance soldered to RF ground - essential for isolation integrity and thermal dissipation. |
| 2 | RF | AC-coupled, 50 Ω matched input - connects directly to antenna or filter output without DC blocking or matching networks. |
| 5 | IF | DC-coupled output - supports baseband signals down to 0 Hz; limited to ±2 mA DC current to prevent die damage. |
| 8 | LO | AC-coupled, 50 Ω matched input - requires +13 to +20 dBm drive; excessive LO power (>+27 dBm) risks permanent damage. |
Key Features
| Feature | Design Value |
|---|---|
| No external bias required | Passive GaAs design eliminates DC power supply, sequencing, and associated noise coupling in sensitive RF stages. |
| On-chip baluns | Enables true double-balanced operation - rejects even-order harmonics and common-mode LO/RF feedthrough without external hybrids. |
| Hermetic SMT package | Provides long-term reliability in harsh environments (space, military) and supports automated reflow assembly without moisture sensitivity concerns. |
| MIL-PRF-38535 screening | Available in Class B or S - ensures lot-to-lot parametric consistency and burn-in validation for mission-critical applications. |
| DC–3 GHz IF bandwidth | Supports zero-IF and low-IF architectures with full baseband capture - eliminates need for external IF AC-coupling capacitors in DC-coupled designs. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC774ALC3 | Wider IF bandwidth (DC–6 GHz), higher LO drive (+23 dBm), but larger 3×3 mm QFN package. | Better suited for ultra-wideband software-defined radios needing >3 GHz IF support. | Select HMC774ALC3 only if IF bandwidth >3 GHz is required; otherwise HMC144LH5TR offers superior size and cost efficiency. |
| QPC1006 | Lower frequency range (5–12 GHz), lower conversion loss (7.5 dB typ), but non-hermetic plastic package. | Targeted at commercial telecom infrastructure where hermeticity and MIL screening are not mandated. | Choose QPC1006 for cost-sensitive, non-military applications below 12 GHz; HMC144LH5TR remains preferred for 12–20 GHz and ruggedized use. |
Compared with HMC774ALC3 and QPC1006, the HMC144LH5TR uniquely balances 6–20 GHz coverage, hermetic reliability, and compact 5×5 mm footprint - making it optimal for space-constrained, high-reliability RF systems where consistent intermodulation performance across temperature and production lots is mandatory.

FAQ
What is the recommended LO drive level for optimal performance of the HMC144LH5TR?
The HMC144LH5TR achieves best conversion loss and IP3 performance at +20 dBm LO drive, with usable operation from +13 to +20 dBm. Driving above +20 dBm yields diminishing returns, and exceeding +27 dBm absolute maximum rating risks permanent damage. For the HMC144LH5TR, maintaining LO drive within this range ensures stable intermodulation and isolation specs across temperature.
Can the HMC144LH5TR be used for DC-coupled IF applications?
Yes - the IF port of the HMC144LH5TR is DC-coupled and supports true 0 Hz operation, provided the connected circuit sources or sinks no more than ±2 mA DC current. Exceeding this limit may cause die malfunction or failure. For the HMC144LH5TR, DC coupling enables zero-IF receiver architectures without external blocking capacitors.
Does the HMC144LH5TR require external baluns or matching components?
No - the HMC144LH5TR integrates on-chip baluns and is internally matched to 50 Ω at RF and LO ports. No external hybrids, transformers, or DC blocking components are needed. This simplifies layout and improves repeatability. The HMC144LH5TR's self-contained architecture reduces bill-of-materials and assembly complexity in high-frequency designs.
What is the thermal resistance and power dissipation limit of the HMC144LH5TR?
The HMC144LH5TR has a channel-to-package-bottom thermal resistance of 101.7 °C/W and a continuous power dissipation limit of 640 mW at 85 °C ambient, derating linearly above that temperature. Proper grounding of all GND pins and the exposed paddle to a low-thermal-resistance PCB ground plane is essential to maintain safe junction temperatures during operation.
Is the HMC144LH5TR suitable for space applications?
Yes - the HMC144LH5TR is offered with MIL-PRF-38535 Class B or S screening, including burn-in, radiation hardness assurance, and lot traceability. Its hermetic ceramic package, –40°C to +85°C operating range, and 150 °C channel temperature rating make it qualified for LEO and GEO satellite payloads. For space programs, the HMC144LH5TR provides proven reliability with documented process controls.
