Product details
Overview
HMC560LM3TR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC passive double-balanced mixer for RF/LO frequencies from 24–40 GHz and IF bandwidth DC–17 GHz, delivering typical conversion loss of 11 dB and input IP3 of +21 dBm. It requires no DC bias, operates as upconverter or downconverter, and is used in millimeter-wave test equipment and point-to-point radios.
For engineers reviewing the HMC560LM3TR datasheet, HMC560LM3TR pinout, HMC560LM3TR application, or HMC560LM3TR equivalent, key selection criteria include its 24–40 GHz RF/LO range, DC–17 GHz IF bandwidth, +21 dBm input IP3, 35 dB LO/RF isolation, and leadless LM3 SMT package with verified 6-pin terminal mapping.
Technical Context
The HMC560LM3TR employs a passive double-balanced topology with on-chip baluns to achieve high LO/RF (35 dB typ), LO/IF (30 dB typ), and RF/IF (20 dB typ) isolations. Its GaAs MESFET process enables broadband operation without external biasing or matching components.
It supports both upconversion and downconversion modes with consistent performance across temperature (−55°C to +85°C) and LO drive levels (+13 dBm nominal). All ports are DC-coupled and 50 Ω matched from 24–40 GHz, with IF port tolerating ±2 mA DC current for true DC–17 GHz operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 24–40 GHz - Enables coverage across Ka-band and extended Q-band radio links without band-switching. |
| IF Bandwidth | DC–17 GHz - Supports baseband, wideband IF, and direct-sampling architectures without AC coupling constraints. |
| Conversion Loss | 11 dB typ - Defines signal path attenuation; impacts system noise figure and required gain staging. |
| Input IP3 | +21 dBm typ - Determines two-tone linearity headroom before third-order intermodulation degrades adjacent channel performance. |
| LO/RF Isolation | 35 dB typ - Minimizes LO leakage into antenna paths, reducing spurious emissions and receiver desensitization. |
| Operating Temperature | −55°C to +85°C - Qualified for military, aerospace, and outdoor fixed wireless deployments. |
| Package | LM3 leadless SMT, 25 mm² - Enables automated assembly and eliminates wirebond variability in millimeter-wave layouts. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | No Connect (N/C) | May be tied to PCB RF ground or left floating; no electrical function but aids mechanical stability and thermal conduction. |
| 4 | RF Port | DC-coupled 50 Ω RF input/output; matched across full 24–40 GHz band; no external matching required. |
| 5 | IF Port | DC-coupled IF interface; supports DC–17 GHz; must limit DC current to ±2 mA to prevent damage or non-function. |
| 6 | LO Port | DC-coupled 50 Ω local oscillator input; matched across 24–40 GHz; accepts +13 dBm nominal drive. |
| GND (package base) | RF Ground Reference | Exposed paddle must be soldered to solid PCB RF ground plane; critical for isolation and impedance control above 24 GHz. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mmWave mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP4E | Wider RF range (18–44 GHz), higher conversion loss (12.5 dB typ), same LM4 package (larger footprint). | Better low-band coverage (18–24 GHz); less suitable for compact Ka-band designs due to larger 6.0 × 6.0 mm package. | Select when broader low-frequency extension is needed and board area permits larger LM4 footprint. |
| QPC1006 | Higher IF bandwidth (DC–20 GHz), slightly lower IP3 (+19 dBm), GaN-based, same 5.0 × 5.0 mm QFN. | Improved power handling (P1dB = +22 dBm), but higher LO drive (+15 dBm) and different thermal profile than GaAs. | Prefer for high-power upconverters where robustness outweighs linearity trade-off; verify LO drive compatibility. |
Compared with HMC1048LP4E and QPC1006, the HMC560LM3TR offers optimal balance of Ka-band linearity (+21 dBm IP3), compact LM3 footprint, and zero-bias simplicity-making it preferred for space-constrained, low-power test and comms platforms requiring DC–17 GHz IF fidelity.

FAQ
What is the recommended LO drive level for the HMC560LM3TR?
The HMC560LM3TR is characterized at +13 dBm LO drive, which delivers optimal conversion loss (11 dB typ), IP3 (+21 dBm), and isolation (35 dB LO/RF). Operating below +11 dBm increases conversion loss; above +15 dBm risks compression or reliability degradation. The datasheet confirms +13 dBm as the nominal design point for all published specs including HMC560LM3TR performance curves.
Does the HMC560LM3TR require DC blocking capacitors on any port?
The HMC560LM3TR RF and LO ports are DC-coupled and 50 Ω matched - no DC blocking is needed. The IF port is also DC-coupled but must not source or sink more than ±2 mA DC current; for non-DC applications, a series capacitor is recommended to block DC while passing the required IF band (e.g., 100 pF for 1–17 GHz). This constraint is explicitly stated in the HMC560LM3TR pin description table.
Can the HMC560LM3TR be used as both an upconverter and downconverter?
Yes - the HMC560LM3TR is bidirectional by design. As a downconverter, RF (24–40 GHz) mixes with LO to produce IF (DC–17 GHz); as an upconverter, IF (DC–17 GHz) mixes with LO to generate RF (24–40 GHz). All published data, including conversion gain vs. frequency plots and spurious tables, validate both modes. The HMC560LM3TR functional diagram and "upconverter performance" section confirm this dual-mode capability.
What is the thermal resistance and maximum power dissipation of the HMC560LM3TR?
The HMC560LM3TR has a channel-to-package-bottom thermal resistance (RTH) of 188 °C/W and a continuous power dissipation limit of 0.344 W at TA = 85 °C, derating 5.3 mW/°C above that temperature. These values are specified in the Absolute Maximum Ratings table and validated under standard LM3 mounting conditions with full ground paddle soldering - critical for maintaining junction temperature below 150 °C in high-density mmWave layouts.
Is the HMC560LM3TR pin-compatible with other LM3-packaged mixers like the HMC562LM3TR?
No - the HMC560LM3TR uses a unique 6-pin LM3 configuration (pins 1–3 N/C, 4=RF, 5=IF, 6=LO), whereas the HMC562LM3TR is a different fundamental mixer with distinct pin assignment (e.g., pin 4=LO, pin 5=RF). Pinouts are not interchangeable; layout reuse requires verification against each device's individual outline drawing. The HMC560LM3TR pin description document explicitly defines its terminal mapping and warns against assuming cross-compatibility.
