Product details
Overview
HMC144LC4TR-R5 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer operating from 6 to 20 GHz, used as an upconverter or downconverter with DC–3 GHz IF bandwidth, +23 dBm input IP3, and 35 dB LO/RF isolation. It enables high-reliability RF front-ends in point-to-point radios and test equipment without external baluns or DC bias.
For engineers reviewing the HMC144LC4TR-R5 datasheet, HMC144LC4TR-R5 pinout, HMC144LC4TR-R5 application, or HMC144LC4TR-R5 equivalent, key selection criteria include its 4×4 mm RoHS-compliant SMT package, broadband 6–20 GHz RF/LO range, DC-coupled IF port, and requirement for full ground paddle soldering per RF design best practices.
Technical Context
The HMC144LC4TR-R5 integrates on-chip baluns enabling true double-balanced operation across 6–20 GHz without external components. Its monolithic GaAs construction delivers consistent conversion loss and isolation over temperature (−40°C to +85°C) and production lots.
It operates with LO drive of +20 dBm, supports both upconversion and downconversion modes, and features DC-coupled IF with ±2 mA absolute max current - requiring external DC blocking for non-DC IF applications. All RF/LO ports are AC-coupled and 50 Ω matched.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range (RF/LO) | 6–20 GHz - Full-band operation without tuning or external matching networks |
| IF Bandwidth | DC to 3 GHz - Supports baseband and wideband IF signals including zero-IF architectures |
| Conversion Loss | 9.5–13 dB typical - Defines signal attenuation from RF to IF path; impacts receiver sensitivity and transmitter output power budget |
| LO–RF Isolation | 25–35 dB typical - Minimizes LO leakage into antenna or RF chain, critical for spurious-free system design |
| Input IP3 | +23 dBm - Determines third-order intermodulation distortion performance in multi-tone environments |
| 1 dB Compression (Input) | +12 to +15 dBm - Sets upper RF input power limit before gain compression degrades linearity |
| Package | 4×4 mm leadless SMT (alumina body, gold-over-nickel finish, MSL3) - Enables automated assembly and high-frequency PCB integration |
Pinout & Package
Package: 24-lead leadless ceramic SMT package (4×4 mm body, alumina substrate, gold-over-nickel plating, exposed ground paddle). Requires full-soldering of ground paddle and all GND pins to PCB RF ground plane per MIL-STD-883 handling guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5–7, 11–14, 18–24 | N/C | No connection - may be tied to RF/DC ground without performance impact |
| 2, 4, 8, 10, 15, 17 | GND | RF/DC ground reference - must connect to PCB ground plane with low-inductance paths |
| 3 | RF | AC-coupled 50 Ω RF port - matched across 6–20 GHz; no external matching required |
| 9 | IF | DC-coupled IF port - supports DC–3 GHz; limits to ±2 mA current to prevent die damage |
| 16 | LO | AC-coupled 50 Ω LO port - matched across 6–20 GHz; requires +20 dBm nominal drive |
Key Features
| Feature | Design Value |
|---|---|
| On-chip balun integration | Eliminates external transformers or lumped baluns - reduces BOM count and layout area while ensuring repeatable balance |
| Leadless RoHS-compliant SMT package | 4×4 mm footprint with exposed ground paddle - optimized for high-frequency thermal and RF grounding in dense RF modules |
| Wide IF bandwidth (DC–3 GHz) | Enables direct-conversion, low-IF, and zero-IF architectures without IF filtering constraints |
| +23 dBm input IP3 at +20 dBm LO | Supports high-dynamic-range receivers in crowded spectral environments (e.g., E-band point-to-point links) |
| ESD rating Class 1A (HBM) | Requires strict ESD handling - mandates grounded wrist straps and ionized air workstations during assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC774ALC3TR | Wider RF range (6–26.5 GHz), higher LO drive (+23 dBm), 28 dB LO–RF isolation | Better suited for millimeter-wave test systems requiring >20 GHz coverage | Select when extending beyond 20 GHz RF or needing higher LO power tolerance |
| ADL5802ACPZ-R7 | Lower frequency (100 MHz–6 GHz), integrated LO buffer, 20 dBm IP3, 32-pin LFCSP | Targeted at sub-6 GHz cellular infrastructure and software-defined radio IF stages | Select for cost-sensitive, lower-frequency designs where LO buffering simplifies driver stage |
Compared with HMC774ALC3TR and ADL5802ACPZ-R7, the HMC144LC4TR-R5 offers optimal balance of 6–20 GHz bandwidth, +23 dBm IP3, and minimal external component count - making it preferred for Ka-band point-to-point and military comms where size, linearity, and broadband performance are co-prioritized.

FAQ
What is the recommended LO drive level for optimal performance of the HMC144LC4TR-R5?
The HMC144LC4TR-R5 achieves best conversion loss, IP3, and isolation at +20 dBm LO drive. Performance degrades below +17 dBm (increased conversion loss) and above +23 dBm (risk of compression or reliability impact). The datasheet specifies +20 dBm as the nominal condition for all key specs including 35 dB LO–RF isolation and +23 dBm IP3.
Can the HMC144LC4TR-R5 be used in zero-IF (direct-conversion) receiver architectures?
Yes, the HMC144LC4TR-R5 supports zero-IF operation due to its DC–3 GHz IF bandwidth and DC-coupled IF port. However, the IF port must not source or sink more than ±2 mA DC current - external DC blocking is required if the baseband circuit cannot meet this constraint. Its balanced topology also suppresses even-order distortion critical in I/Q demodulators.
Is the HMC144LC4TR-R5 pin-compatible with other Hittite mixer variants like HMC144LC3 or HMC144LC5?
No, the HMC144LC4TR-R5 is not pin-compatible with HMC144LC3 or HMC144LC5. While all belong to the same functional family, the HMC144LC4 uses a 24-lead 4×4 mm package with specific pin assignments (e.g., RF on Pin 3, LO on Pin 16, IF on Pin 9); LC3 and LC5 use different footprints and pinouts per their respective datasheets.
What PCB grounding requirements apply to the HMC144LC4TR-R5's exposed paddle?
The exposed ground paddle of the HMC144LC4TR-R5 must be fully soldered to a solid RF ground plane using multiple thermal vias (≥8, 0.3 mm diameter) connecting to inner and bottom ground layers. Incomplete paddle soldering causes degraded isolation, increased conversion loss, and thermal runaway under high LO drive - per Hittite Application Note AN-10-01.
Does the HMC144LC4TR-R5 require external baluns or matching components for 6–20 GHz operation?
No, the HMC144LC4TR-R5 integrates on-chip baluns for all ports and is internally matched to 50 Ω across 6–20 GHz. No external baluns, transformers, or matching networks are needed for standard operation - simplifying layout and improving production yield versus hybrid diode mixers.
