Product details
Overview
HMC663LC3TR 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 point-to-point radios and test equipment.
For engineers reviewing the HMC663LC3TR datasheet, HMC663LC3TR pinout, HMC663LC3TR application, or HMC663LC3TR equivalent, this device requires no DC bias, supports high-side LO injection, operates with +17 to +23 dBm LO drive, and integrates optimized balun structures for superior isolation without external matching components.
Technical Context
The HMC663LC3TR employs a passive double-balanced topology fabricated in GaAs MESFET process, enabling true broadband operation across 6–12 GHz RF with DC-coupled IF port and AC-coupled LO/RF ports matched to 50 Ω. Its balun architecture delivers simultaneous high LO-to-RF (40 dB typ) and LO-to-IF (42 dB typ) isolation.
It functions as both upconverter and downconverter with no DC power required, supports IF bandwidth extending to DC (with ≤2 mA current limit), and maintains stable conversion loss and IP3 over –40°C to +85°C ambient temperature - validated per electrical specifications at TA = +25°C, IF = 100 MHz, LO = +21 dBm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 6–12 GHz - enables full coverage of X-band for radar and licensed wireless links. |
| LO Frequency Range | 6–14 GHz - supports high-side LO injection for downconversion and flexible upconversion schemes. |
| IF Frequency Range | DC–4 GHz - allows baseband and low-IF architectures including zero-IF receivers. |
| Conversion Loss | 8 dB typical - defines signal attenuation between RF and IF ports; impacts system noise figure and gain budget. |
| Input IP3 | 30 dBm - determines third-order intermodulation distortion performance in multi-tone environments. |
| LO-to-RF Isolation | 40 dB typical - minimizes LO leakage into antenna or RF front-end, reducing self-interference. |
| Package | 16-lead ceramic 3×3 mm SMT (alumina body, gold-over-nickel finish, MSL3) - compatible with automated reflow assembly and RF grounding via paddle and multiple ground pins. |
Pinout & Package

| 2 | LO | AC-coupled 50 Ω input; accepts +17 to +23 dBm LO drive without external matching. |
| 3, 6, 15 | GND | RF/DC ground terminals; must be soldered to PCB ground plane along with exposed paddle. |
| 7 | IF | DC-coupled output/input; supports DC–4 GHz; limited to ±2 mA current to prevent damage. |

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 (4–14 GHz), higher conversion loss (9.5 dB typ), same 16-lead 3×3 mm package. | Better suited for 4–6 GHz legacy bands; less optimal for X-band-only designs due to higher loss. | Select when broader low-band coverage is needed and 1.5 dB extra loss is acceptable. |
| QPC1006 | Higher IP3 (33 dBm), wider IF bandwidth (DC–6 GHz), but requires +24 dBm LO drive and uses different 16-lead 4×4 mm QFN. | Preferred for ultra-high-linearity test systems; incompatible pinout and board layout. | Choose for demanding lab-grade instrumentation where layout redesign is feasible. |
Compared with HMC1048LP3E and QPC1006, the HMC663LC3TR offers the best balance of X-band optimization, low LO drive sensitivity (+17 dBm min), and drop-in compatibility in space-constrained 3×3 mm layouts - making it ideal for production-grade microwave radios.

FAQ
What is the minimum LO drive level required for specified performance of the HMC663LC3TR?
The HMC663LC3TR achieves datasheet-specified conversion loss, isolation, and IP3 with a minimum LO drive of +17 dBm. Performance degrades below this level - e.g., conversion loss increases by ~1.5 dB at +15 dBm. The device remains functional but does not meet guaranteed specs below +17 dBm, as confirmed in the "Conversion Gain vs. LO Drive" plots on page 2 of the datasheet.
Can the HMC663LC3TR be used for DC-coupled IF operation, and what are the current limits?
Yes, the HMC663LC3TR supports true DC-coupled IF operation via Pin 7. However, the IF port must not source or sink more than ±2 mA DC current - exceeding this risks non-function or permanent damage. This constraint is explicitly stated in the Pin Descriptions section (page 6) and applies regardless of IF frequency or signal amplitude.
Is the HMC663LC3TR pin-compatible with other Hittite 3×3 mm mixer packages like the HMC662LC3TR?
No, the HMC663LC3TR is not pin-compatible with HMC662LC3TR. While both use 16-lead 3×3 mm ceramic packages, their pin functions differ: HMC663LC3TR assigns Pin 7 to IF and Pin 14 to RF, whereas HMC662LC3TR swaps these roles (Pin 7 = RF, Pin 14 = IF). Layout reuse is not possible without redesign.
Does the HMC663LC3TR require external matching components for 50 Ω operation at RF and LO ports?
No, the HMC663LC3TR RF and LO ports (Pins 14 and 2) are internally AC-coupled and impedance-matched to 50 Ω across 6–12 GHz and 6–14 GHz respectively. The datasheet states "no external components or matching circuitry" are needed - verified by S-parameter data showing < –10 dB return loss across full bands.
What is the thermal resistance and maximum continuous power dissipation of the HMC663LC3TR?
The HMC663LC3TR has a channel-to-ground-paddle thermal resistance (θJG) of 60 °C/W. At TA = 85 °C, maximum continuous power dissipation is 1.08 W; above 85 °C, it derates linearly at 17 mW/°C. These values are specified in the Absolute Maximum Ratings table (page 4) and assume proper soldering of all ground pins and the exposed paddle to a thermal pad.
