Product details
Overview
HMC519LC4 from Analog Devices is a GaAs pHEMT MMIC low-noise amplifier operating from 18 to 31 GHz, delivering 14 dB small-signal gain, 3.5 dB noise figure, and +23 dBm output IP3 at +3 V/75 mA. It functions as an LNA or LO driver in microwave radio front-ends and VSAT systems.
For engineers reviewing the HMC519LC4 datasheet, HMC519LC4 pinout, HMC519LC4 application, or HMC519LC4 equivalent, key selection criteria include its 18–31 GHz bandwidth, 50 Ω matched I/Os, DC-blocked ports, 4×4 mm ceramic LCC package, and suitability for high-frequency receiver chains requiring low noise and high linearity.
Technical Context
The HMC519LC4 employs a monolithic GaAs pHEMT process to achieve broadband low-noise amplification across two overlapping bands: 18–28 GHz (min gain 11.4 dB) and 28–31 GHz (min gain 10.2 dB). Its internally matched 50 Ω input/output eliminates external matching networks.
It features three independent drain supply pins (Vdd1, Vdd2, Vdd3), all rated for +3 V operation, and integrates DC blocking on both RFIN and RFOUT. The exposed paddle must be soldered to RF/DC ground for thermal and electrical performance.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5–14, 18, 20, 22, 24 | N/C | No internal connection - must remain unconnected or grounded per layout guidelines |
| 2, 4, 15, 17 | GND | RF/DC ground terminals - connect directly to top-layer ground plane and exposed paddle |
| 3 | RFIN | AC-coupled 50 Ω RF input - requires no external matching network |
| 16 | RFOUT | AC-coupled 50 Ω RF output - compatible with standard 2.92 mm connectors and microstrip lines |
| 19, 21, 23 | Vdd3, Vdd2, Vdd1 | Independent drain supply inputs - each requires local decoupling (C1–C6 per eval board) |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC465LP5E | Wider 2–20 GHz range, lower 2.5 dB NF, but only +17 dBm IP3 and +8 dBm P1dB | Optimized for sub-20 GHz radar and EW; insufficient output power for 28 GHz LO driving | Select when bandwidth below 18 GHz is required and higher gain flatness is prioritized over E-band coverage |
| QPL9547 | SiGe process, 16–32 GHz, 3.8 dB NF, +20 dBm IP3, +10 dBm P1dB, +5 V supply | Higher supply voltage, lower linearity, and wider process variation vs. GaAs; suited for cost-sensitive commercial mmWave | Select when BOM cost reduction outweighs 0.3 dB NF penalty and 3 dB IP3 loss in non-mission-critical infrastructure |
Compared with HMC519LC4, HMC465LP5E trades E-band coverage for broader low-frequency utility, while QPL9547 offers SiGe cost benefits at the expense of GaAs-level noise and linearity-making HMC519LC4 optimal for high-performance E-band LNA or LO driver roles where 3.5 dB NF and +23 dBm IP3 are design-critical.

FAQ
What is the operating temperature range for the HMC519LC4?
The HMC519LC4 is specified for continuous operation from −40°C to +85°C ambient temperature. Its thermal resistance (channel-to-package bottom) is 76.9 °C/W, and the absolute maximum channel temperature is 175°C. Derating begins above 85°C at 13 mW/°C. This range supports deployment in outdoor wireless infrastructure and airborne radar platforms where environmental extremes are expected. The HMC519LC4 maintains specified gain, noise figure, and IP3 across this full range per characterization data in the datasheet.
Does the HMC519LC4 require external matching components?
No, the HMC519LC4 features internally matched 50 Ω input and output ports with integrated DC blocking, eliminating the need for external matching networks or series DC-blocking capacitors in most standard microwave layouts. However, proper grounding of the exposed paddle and use of recommended decoupling capacitors (100 pF, 1000 pF, and 4.7 µF per supply pin) are mandatory for specified RF performance. The HMC519LC4 evaluation board (119667) validates this match without added tuning elements.
Can the HMC519LC4 be used as an LO driver?
Yes, the HMC519LC4 is explicitly qualified as an LO driver due to its +11 dBm P1dB output power and +23 dBm output IP3, enabling it to drive balanced, I/Q, or image-reject mixers without additional gain stages. Its 18–31 GHz bandwidth covers common LO frequencies for E-band transceivers and Ka-band satellite modems. The HMC519LC4's gain flatness and low harmonic content further support clean local oscillator signal generation in high-fidelity RF architectures.
What is the ESD sensitivity rating of the HMC519LC4?
The HMC519LC4 has an ESD sensitivity rating of Class 1B per the Human Body Model (HBM), corresponding to a withstand voltage of 250–500 V. This classification mandates strict handling precautions-including grounded workstations, anti-static packaging, and ionized air environments-during assembly and test. The device's GaAs pHEMT process inherently exhibits lower ESD tolerance than silicon-based amplifiers, making adherence to Analog Devices' handling guidelines essential to prevent latent damage. The HMC519LC4 datasheet explicitly labels it as an "Electrostatic Sensitive Device."
Is the HMC519LC4 pin-compatible with other HMC LNA variants?
No, the HMC519LC4 is not pin-compatible with other HMC-series LNAs such as HMC465LP5E or HMC564LC4. Its 24-pin 4×4 mm LCC footprint, with dedicated Vdd1/Vdd2/Vdd3 pins and specific NC/GND assignments, is unique to this part. Pinout differences include distinct power pin locations and grounding terminal distribution. Substitution requires PCB redesign. The HMC519LC4 datasheet does not list any drop-in replacements, and its outline drawing (PKG-004840) confirms mechanical and electrical uniqueness within the Hittite portfolio.
