Product details
Overview
HMC526LC4 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC I/Q mixer operating as an image-reject mixer (IRM) or single-sideband upconverter in 6–10 GHz RF/LO bands, with DC–3.5 GHz IF bandwidth, 9.5 dB typical conversion loss, 40 dB image rejection, and +28 dBm input IP3 - deployed in point-to-point radios and military RF front-ends.
For engineers reviewing the HMC526LC4 datasheet, HMC526LC4 pinout, HMC526LC4 application, or HMC526LC4 equivalent, key selection criteria include its 4×4 mm leadless SMT package, LO-driven quadrature architecture, RF/IF/LO port isolation specs, and compatibility with surface-mount manufacturing without wire bonding.
Technical Context
The HMC526LC4 integrates two double-balanced GaAs MESFET mixer cells with an on-die 90° hybrid to enable image rejection or SSB upconversion; it requires external IF hybrid for IRM operation but supports direct DC-coupled IF1/IF2 outputs. Its RF and LO ports are AC-coupled and 50 Ω matched across 6–10 GHz.
Operation relies on precise amplitude/phase balance (≤0.2 dB / ≤5°) between quadrature channels, with LO drive sensitivity at +19 dBm (typical), and thermal limits defined by 128 °C/W junction-to-bottom thermal resistance and -40°C to +85°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 6–10 GHz - fully specified band for RF input and LO drive, enabling use in X-band wireless infrastructure |
| IF Bandwidth | DC–3.5 GHz - supports baseband I/Q demodulation and wideband IF sampling without external DC blocking |
| Conversion Loss (IRM) | 7.5–9.5 dB (typ) - defines signal attenuation in downconversion mode; impacts receiver noise figure budget |
| Image Rejection | 28–40 dB (typ/max) - determines adjacent-channel interference suppression capability in zero-IF architectures |
| Input IP3 | +25 to +30 dBm - sets third-order intermodulation dynamic range limit for multi-carrier RF environments |
| LO–RF Isolation | 38–50 dB (min/max) - reduces LO leakage into antenna path, easing filter requirements in transceiver designs |
| Amplitude & Phase Balance | ≤0.2 dB / ≤5° - critical for achieving >35 dB image rejection; degrades with frequency and temperature |
Pinout & Package
Package: 24-lead 4×4 mm leadless SMT (alumina body, gold-over-nickel plating, MSL3, exposed ground paddle). All ground pins (3,5,12,14,16) and paddle must be soldered to PCB RF ground.

Equivalent & Alternatives
The following parts are listed as comparable options for similar I/Q mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC8192LP5E | Wider RF range (4–14 GHz), higher conversion gain (+3 dB), but larger 5×5 mm package and +23 dBm IP3 | Better suited for multi-band test equipment; less optimal for space-constrained 7–8.5 GHz radios | Select HMC8192LP5E when wider frequency coverage and gain outweigh size constraints |
| ADL5375-05 | Lower frequency (300–4000 MHz), integrated LO buffer, +22 dBm IP3, and 0.5 dB higher conversion loss | Targets sub-6 GHz cellular infrastructure; not usable above 4 GHz | Choose ADL5375-05 only for LTE/5G FR1 upconverters - incompatible with X-band operation |
Compared with HMC8192LP5E and ADL5375-05, the HMC526LC4 delivers optimal trade-off of X-band coverage, compact 4×4 mm footprint, and +28 dBm linearity - making it the preferred choice for size- and performance-sensitive 6–10 GHz IRM designs.

FAQ
What is the recommended LO drive level for optimal performance of the HMC526LC4?
The HMC526LC4 achieves best image rejection and conversion loss at +19 dBm LO drive (typical), as validated in datasheet measurements. Driving below +17 dBm increases conversion loss and degrades amplitude/phase balance; exceeding +21 dBm risks compression and spurious generation. Always verify LO power at the HMC526LC4 pin using calibrated RF source and directional coupler.
Can the HMC526LC4 operate as both an image-reject mixer and a single-sideband upconverter?
Yes, the HMC526LC4 supports both modes: as an image-reject mixer (IRM) when used with an external IF hybrid, and as a single-sideband upconverter when driven differentially at IF1/IF2. The datasheet confirms identical RF/LO/IF port definitions and performance specs apply in both configurations, with no hardware change required.
What are the absolute maximum ratings for RF/IF input and LO drive on the HMC526LC4?
The HMC526LC4 has absolute maximum ratings of +20 dBm for RF/IF input and +27 dBm for LO drive. Exceeding these values risks permanent damage. For reliable operation, keep RF/IF inputs ≤+15 dBm and LO drive ≤+21 dBm - especially at elevated temperatures where thermal derating applies (507 mW max dissipation at 85°C, derated 7.8 mW/°C above).
How should the ground connections be implemented for the HMC526LC4 to ensure RF performance?
All GND pins (3,5,12,14,16) and the exposed bottom paddle must be soldered directly to a solid, low-inductance RF ground plane using multiple thermal vias. The datasheet mandates this for thermal management and RF return path integrity. Floating or poorly connected grounds cause degraded isolation, increased conversion loss, and instability above 8 GHz.
Is the HMC526LC4 compatible with standard PCB assembly processes including lead-free reflow?
Yes, the HMC526LC4 is RoHS-compliant and rated MSL3 with peak reflow temperature tolerance of 260°C. Its gold-over-nickel finish and alumina package withstand standard lead-free reflow profiles. However, avoid repeated thermal cycling and ensure uniform heating to prevent die stress - follow Analog Devices' recommended reflow profile in the package documentation for HMC526LC4.
