Product details
Overview
HMC517LC4 from Analog Devices is a GaAs pHEMT MMIC low-noise amplifier operating from 17–26 GHz, delivering 19 dB small-signal gain, 2.5 dB noise figure, +13 dBm P1dB output power, and +23 dBm OIP3. It functions as both an LNA and LO driver for balanced or image-reject mixers in millimeter-wave radio systems.
For engineers reviewing the HMC517LC4 datasheet, HMC517LC4 pinout, HMC517LC4 application, or HMC517LC4 equivalent, key selection criteria include its 17–26 GHz bandwidth, 50 Ω input/output matching, +3 V/67 mA single-supply operation, RoHS-compliant 4×4 mm ceramic LCC package, and suitability for high-frequency test equipment and point-to-point radios.
Technical Context
The HMC517LC4 integrates three independently biased GaAs pHEMT gain stages in a monolithic MMIC architecture, enabling broadband 17–26 GHz operation with flat gain response and stable noise performance across temperature. Its internal bias network supports single +3 V supply while maintaining consistent P1dB and IP3 over –40°C to +85°C.
Input and output ports are DC-blocked and 50 Ω matched without external tuning, and the exposed paddle provides thermal path to PCB ground. The device requires external bypassing (100 pF, 1 nF, 2.2 µF per supply pin) and operates with Class A biasing for linear amplification and LO drive fidelity.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC465LP5 | Wider 2–20 GHz range; lower 1.8 dB NF but only 15 dB gain; 5×5 mm QFN package | Better for sub-20 GHz wideband systems; not suitable for 22–26 GHz operation | Select HMC465LP5 when frequency coverage below 17 GHz is required and higher gain is not critical |
| Qorvo QPL9547 | 20–30 GHz range; 18 dB gain, 2.7 dB NF, +21 dBm OIP3; 2.5×2.5 mm QFN | Extends upper band to 30 GHz; smaller footprint but lower OIP3 and higher NF than HMC517LC4 | Select QPL9547 when board space is constrained and operation above 26 GHz is needed |

FAQ
What is the operating frequency range of the HMC517LC4?
The HMC517LC4 operates from 17 to 26 GHz, with full electrical specifications provided across two sub-bands: 17–22 GHz and 22–26 GHz. Performance parameters-including gain, noise figure, and return loss-are guaranteed across this entire range at +25°C and within –40°C to +85°C operating temperature. The HMC517LC4 maintains stable RF characteristics without external tuning in both bands.
Does the HMC517LC4 require external matching components?
No, the HMC517LC4 features internally matched 50 Ω input and output ports, eliminating the need for external matching networks in standard microstrip designs. Both RFIN (Pin 3) and RFOUT (Pin 16) are AC-coupled and impedance-matched, allowing direct integration into 50 Ω RF signal paths. External DC blocking is only required if the driving or load circuit introduces DC voltage.
What supply voltage and current does the HMC517LC4 use?
The HMC517LC4 operates from a single +3 V DC supply, drawing 67 mA typical at +25°C. It supports operation from +2.5 V to +3.5 V, with supply current varying from 66 mA to 71 mA across that range. Three separate Vdd pins (19, 21, 23) require individual bypassing using 100 pF, 1 nF, and 2.2 µF capacitors per pin for optimal RF stability.
How is thermal management handled on the HMC517LC4?
The HMC517LC4 uses an exposed paddle for thermal conduction, with a specified channel-to-pad thermal resistance of 76.9 °C/W. For reliable operation, the paddle must be soldered to a large, multi-via-connected PCB ground plane. At +85°C ambient and +3 V bias, the die temperature remains within safe limits (<125°C) when the board provides ≥1.2 W total dissipation capability, as validated in the HMC517LC4 evaluation setup.
Is the HMC517LC4 suitable for use as an LO driver?
Yes, the HMC517LC4 is explicitly qualified as an LO driver for balanced, I/Q, and image-reject mixers due to its +13 dBm P1dB output power and +23 dBm OIP3. Its high linearity and broadband 17–26 GHz response enable clean LO signal generation without harmonic filtering. The HMC517LC4 has been validated in reference designs driving HMC mixers such as the HMC774A and HMC1040, confirming robust drive capability and phase stability.
