Product details
Overview
HMC663LC3TR-R5 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced passive mixer operating from 6–12 GHz RF, 6–14 GHz LO, and DC–4 GHz IF, delivering 8 dB typical conversion loss, 30 dBm input IP3, and 40 dB LO-to-RF isolation - ideal for high-linearity up/downconversion in microwave radios and test equipment.
For engineers reviewing the HMC663LC3TR-R5 datasheet, HMC663LC3TR-R5 pinout, HMC663LC3TR-R5 application, or HMC663LC3TR-R5 equivalent, this device requires no DC bias, supports high-side or low-side LO injection, operates with +17 to +23 dBm LO drive, and integrates optimized balun structures for robust port isolation in compact 3×3 mm ceramic SMT packaging.
Technical Context
The HMC663LC3TR-R5 implements a passive double-balanced topology using GaAs MESFET process technology, enabling true broadband operation without external matching components or DC bias circuitry. Its symmetrical balun architecture delivers simultaneous high LO-to-RF (40 dB typ) and LO-to-IF (42 dB typ) isolation across the full 6–12 GHz RF band.
It supports both upconverter and downconverter configurations with fixed IF bandwidth (DC–4 GHz), wide LO range (6–14 GHz), and stable performance over −40°C to +85°C. Conversion loss remains ≤12 dB across temperature and frequency, while input P1dB reaches 20 dBm at +25°C - confirming suitability for medium-power microwave signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 6–12 GHz - covers X-band radar, point-to-point backhaul, and satellite uplink bands. |
| LO Frequency Range | 6–14 GHz - enables flexible high-side/low-side injection for harmonic suppression and image rejection. |
| IF Bandwidth | DC–4 GHz - supports baseband I/Q modulation, wideband IF sampling, and DC-coupled receiver architectures. |
| Conversion Loss | 8 dB typ (max 12 dB) - defines signal path attenuation; lower values reduce system noise figure impact. |
| Input IP3 | 30 dBm - determines two-tone intermodulation distortion floor; critical for dense-spectrum multi-carrier systems. |
| LO-to-RF Isolation | 40 dB typ - minimizes LO leakage into antenna or RF front-end, easing filtering requirements. |
| Operating Temp | −40°C to +85°C - validated for outdoor wireless infrastructure and military-grade environmental operation. |
Pinout & Package
Package: 16-lead leadless ceramic SMT package (3×3 mm, 9 mm² body), alumina substrate, gold-over-nickel plating, MSL3 rated, with exposed ground paddle requiring soldering to PCB RF ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 5, 8–13, 16 | N/C | No internal connection; must remain unconnected per design - floating pins may degrade RF performance. |
| 2 | LO | AC-coupled 50 Ω matched input; accepts +17 to +23 dBm LO drive without external bias or matching. |
| 3, 6, 15 | GND | RF/DC ground terminals; must be soldered directly to PCB ground plane alongside exposed paddle. |
| 7 | IF | DC-coupled output; supports DC–4 GHz IF; current-limited to ±2 mA to prevent damage in DC-coupled use. |
| 14 | RF | AC-coupled 50 Ω matched input/output; used as RF port in downconversion or upconversion mode. |
Key Features
| Feature | Design Value |
|---|---|
| No DC bias required | Eliminates bias network complexity, reduces BOM count, and improves reliability in high-frequency signal paths. |
| Passive double-balanced topology | Suppresses even-order harmonics and LO/RF feedthrough, simplifying post-mixer filtering in sensitive receivers. |
| High LO-to-RF/IF isolation | Reduces need for external LO suppression filters, lowering system insertion loss and board space in transceivers. |
| Wide IF bandwidth (DC–4 GHz) | Enables direct sampling of complex modulated waveforms and supports zero-IF and low-IF receiver architectures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF range (4–16 GHz), higher conversion loss (9.5 dB typ), same 3×3 mm package. | Better suited for wideband test equipment covering C through Ku bands; less optimal for narrow X-band radios where HMC663LC3TR-R5's lower loss matters. | Select HMC1048LP3E when broader frequency coverage outweighs 1.5 dB conversion loss penalty. |
| QPC1006 | Higher IP3 (33 dBm), wider IF (DC–6 GHz), but requires +24 dBm LO drive and larger 4×4 mm QFN package. | Preferred for high-dynamic-range 5G FR2 base station receivers needing >30 dBm IP3 and extended IF bandwidth beyond 4 GHz. | Choose QPC1006 only if system LO power budget allows +24 dBm and PCB layout accommodates larger footprint. |
Compared with HMC1048LP3E and QPC1006, the HMC663LC3TR-R5 offers the best balance of low conversion loss (8 dB), moderate LO drive (+17 dBm min), and compact 3×3 mm footprint - making it optimal for size-constrained, power-efficient X-band radios where linearity and thermal stability are prioritized over ultra-wideband coverage.

FAQ
What is the minimum LO drive level required for specified performance of the HMC663LC3TR-R5?
The HMC663LC3TR-R5 achieves its datasheet-specified conversion loss, isolation, and IP3 performance with a minimum LO drive of +17 dBm. At +17 dBm, conversion loss remains ≤12 dB and LO-to-RF isolation stays ≥29 dB across 6–12 GHz. Lower LO power degrades conversion efficiency and increases noise figure, so +17 dBm is the validated operational floor for full specification compliance.
Can the HMC663LC3TR-R5 be used in zero-IF (direct-conversion) receiver architectures?
Yes, the HMC663LC3TR-R5 supports zero-IF operation because its IF port is DC-coupled and rated for DC–4 GHz bandwidth. However, the IF output must not source or sink more than ±2 mA DC current - exceeding this limit risks non-function or permanent damage. For true DC-coupled use, ensure downstream circuitry presents high impedance or includes current-limiting protection.
Is the HMC663LC3TR-R5 pin-compatible with other Hittite mixer variants like HMC662LC3 or HMC664LC3?
No, the HMC663LC3TR-R5 is not pin-compatible with HMC662LC3 or HMC664LC3. While all three share the same 3×3 mm ceramic package outline, their pin functions differ: HMC662LC3 uses pin 7 as RF and pin 14 as IF, whereas HMC663LC3TR-R5 assigns pin 7 as IF and pin 14 as RF. PCB layout must be redesigned to match the HMC663LC3TR-R5 pinout.
What is the thermal resistance and maximum power dissipation of the HMC663LC3TR-R5?
The HMC663LC3TR-R5 has a channel-to-ground paddle thermal resistance of 60°C/W. At 85°C case temperature, its continuous power dissipation is 1.08 W, derating linearly by 17 mW/°C above 85°C. This allows safe operation up to 150°C channel temperature - critical for conduction-cooled RF modules in sealed enclosures.
Does the HMC663LC3TR-R5 require external matching components for 50 Ω operation?
No, the HMC663LC3TR-R5 does not require external matching components. Its LO and RF ports are internally AC-coupled and 50 Ω matched, and the IF port is DC-coupled with 50 Ω characteristic impedance. The device is designed for direct integration into 50 Ω microstrip layouts - only proper grounding of all GND pins and the exposed paddle is required for optimal RF performance.
