Product details
Overview
HMC1041LC4 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC I/Q mixer operating from 17–27 GHz RF/LO, supporting DC–3.5 GHz IF bandwidth, delivering 36 dB image rejection and +20 dBm input IP3 in a 24-lead 4×4 mm SMT package-designed for high-frequency point-to-point radio and military receivers.
For engineers reviewing the HMC1041LC4 datasheet, HMC1041LC4 pinout, HMC1041LC4 application, or HMC1041LC4 equivalent, this page provides verified RF performance data, validated I/Q architecture details, confirmed thermal and isolation specs, and real-world evaluation board interface guidance.
Technical Context
The HMC1041LC4 integrates two double-balanced GaAs MESFET mixer cells with an on-die 90° hybrid to enable image-reject downconversion or single-sideband upconversion without external quadrature components. It operates as an IRM with external IF 90° hybrid or standalone USB upconverter at 1 GHz IF.
Its architecture supports both USB and LSB modes across full 17–27 GHz RF range, with measured amplitude balance ±0.25 dB and phase balance ±1.5° at 1 GHz IF, and maintains ≥45 dB LO-to-RF isolation and ≥40 dB LO-to-IF isolation under +15 dBm LO drive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 17–27 GHz - covers E-band point-to-point links and military SATCOM uplink bands. |
| IF Bandwidth | DC–3.5 GHz - enables baseband I/Q demodulation and wideband SSB upconversion without IF filtering constraints. |
| Image Rejection | Typ. 36 dB - suppresses unwanted sideband by >36 dB, reducing post-mixer filtering requirements in IRM mode. |
| Input IP3 | +20 dBm - supports high-dynamic-range receiver front-ends with minimal intermodulation distortion. |
| LO-to-RF Isolation | Typ. 45 dB - minimizes LO leakage into antenna path, critical for full-duplex and sensitive receive chains. |
| Conversion Loss (IRM) | Typ. 9–12 dB - defines signal attenuation in image-reject mode; impacts system noise figure budget. |
| Package | 24-lead 4×4 mm leadless SMT (alumina body, gold-over-nickel finish, MSL3) - enables high-frequency PCB assembly with low parasitic inductance. |
Pinout & Package
24-lead 4×4 mm leadless surface-mount package with exposed ground paddle; alumina ceramic body, gold-over-nickel plating, moisture sensitivity level 3 (MSL3), peak reflow 260°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 6, 7, 10, 12, 13, 17–24 | N/C | Internally unconnected; must be externally grounded per RF layout best practice to minimize cavity resonance. |
| 3, 5, 8, 14, 16 | GND | RF/DC ground terminals; require low-inductance connection to PCB ground plane alongside exposed paddle. |
| 4 | RF | 50 Ω AC-coupled RF input port; matched across 17–27 GHz for direct integration into E-band transceiver chains. |
| 9 | IF2 | DC-coupled I-channel IF output; supports DC–3.5 GHz operation but limited to ±3 mA current to prevent damage. |
| 11 | IF1 | DC-coupled Q-channel IF output; identical electrical behavior to IF2, enabling true I/Q baseband extraction. |
| 15 | LO | 50 Ω AC-coupled LO input port; specified for +13 to +17 dBm drive, optimized for 17–27 GHz local oscillator injection. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar I/Q mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1040LC4 | 13–20 GHz RF range, lower upper frequency limit; otherwise identical architecture and pinout. | Suitable for K-band systems only; not usable in 24+ GHz E-band or military 27 GHz links. | Select when operating exclusively below 20 GHz and cost optimization is prioritized over bandwidth. |
| Qorvo QM11020 | 17–27 GHz range, GaAs pHEMT process, but requires external 90° hybrid and has no integrated IF hybrid. | Higher board-level complexity due to discrete hybrid; wider IF bandwidth (DC–6 GHz) but lower image rejection (28 dB typ). | Choose when maximum IF bandwidth is critical and layout space allows external hybrid integration. |
Compared with HMC1041LC4, HMC1040LC4 trades bandwidth for cost in K-band, while QM11020 offers extended IF bandwidth at the expense of image rejection and increased layout complexity-neither is pin-compatible, but all three serve overlapping E/K-band I/Q conversion roles.

FAQ
What is the recommended LO drive level for optimal performance of the HMC1041LC4?
The HMC1041LC4 achieves best image rejection and conversion gain uniformity at +15 dBm LO drive, with functional operation supported from +13 dBm to +17 dBm. Operating outside this range degrades amplitude/phase balance and increases conversion loss variation across the 17–27 GHz band. The HMC1041LC4 datasheet specifies +15 dBm as the reference condition for all typical performance curves including image rejection and IP3.
Can the HMC1041LC4 operate in both image-reject downconversion and single-sideband upconversion modes?
Yes, the HMC1041LC4 supports both modes: as an image-reject mixer (IRM) using external IF 90° hybrid for downconversion, and as a single-sideband upconverter (USB or LSB) without external hybrid. Its internal dual-mixer cell and on-die 90° hybrid allow flexible configuration-verified in datasheet plots showing USB/LSB conversion gain, sideband rejection, and image rejection across temperature and LO drive.
What is the maximum allowable current on the IF1 and IF2 pins of the HMC1041LC4?
The HMC1041LC4 IF1 and IF2 pins are DC-coupled and must not source or sink more than ±3 mA of current to avoid non-function or permanent damage. This limit applies regardless of IF frequency or DC bias condition. The HMC1041LC4 datasheet explicitly warns that exceeding this current threshold risks device failure, especially during DC-coupled baseband interfacing with active analog circuitry.
Does the HMC1041LC4 require external matching networks at RF, LO, or IF ports?
No-the HMC1041LC4 features internally matched 50 Ω RF and LO ports across 17–27 GHz, and DC-coupled IF1/IF2 ports designed for direct connection to baseband amplifiers or ADC drivers. External matching is unnecessary for nominal operation; however, the datasheet recommends grounding all N/C pins and ensuring low-inductance connections to the exposed paddle for optimal RF performance.
Is the HMC1041LC4 pin-compatible with other Hittite I/Q mixers such as the HMC1040LC4?
Yes, the HMC1041LC4 shares identical 24-lead 4×4 mm package footprint, pin numbering, and pin functions with the HMC1040LC4, enabling drop-in replacement in K-band designs. Both devices use the same pinout: RF on pin 4, LO on pin 15, IF1 on pin 11, IF2 on pin 9, and GND on pins 3/5/8/14/16. This compatibility is confirmed in Hittite's package documentation and evaluation board layouts.
