Product details
Overview
HMC716LP3E from Analog Devices (formerly Hittite Microwave) is a GaAs pHEMT MMIC low-noise amplifier optimized for 3.1–3.9 GHz fixed wireless and LTE/WiMAX/4G base station front-end receivers. It delivers 1 dB noise figure, 18 dB gain, +33 dBm output IP3 at +5 V supply, with 50 Ω matched input/output and minimal external matching requirements.
For engineers reviewing the HMC716LP3E datasheet, HMC716LP3E pinout, HMC716LP3E application, or HMC716LP3E equivalent, key selection criteria include its adjustable bias current via external resistor, dual-supply operation (+3 V to +5 V), temperature-stable gain/noise performance, and QFN-16 package compatibility with RF layout best practices.
Technical Context
The HMC716LP3E employs a single-stage GaAs pHEMT architecture with DC-coupled input and AC-coupled 50 Ω output. Its bias current is externally set via resistor on the RES pin, enabling linearity–power trade-off tuning across supply voltages.
It operates over –40 °C to +85 °C with thermal resistance of 90 °C/W (channel-to-paddle), requiring direct soldering of the exposed ground paddle to PCB RF ground. Absolute maximum drain voltage is +5.5 V, and ESD rating is Class 1A (HBM).

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1099LP3E | Wider 2.3–4.0 GHz bandwidth; 0.9 dB NF; +32 dBm OIP3; same 3×3 mm QFN package. | Optimized for broader multi-band infrastructure; slightly lower linearity at 3.5 GHz. | Select when coverage beyond 3.9 GHz (e.g., 3.8–4.0 GHz LTE bands) is required. |
| QPL9057 | 3.3–3.8 GHz range; 0.75 dB NF; +31 dBm OIP3; 2×2 mm DFN package; integrated active bias. | Smaller footprint and lower NF, but reduced OIP3 and no external bias adjustment. | Select for space-constrained femtocells where ultimate linearity is secondary to size and noise. |
Compared with HMC716LP3E, HMC1099LP3E extends usable bandwidth upward by 100 MHz with near-identical noise and linearity, while QPL9057 trades adjustability and OIP3 for smaller size and lower NF-making HMC716LP3E optimal for 3.1–3.9 GHz infrastructure where bias tuning and robust third-order suppression are prioritized.

FAQ
What is the recommended external bias resistor value for HMC716LP3E at +5 V supply?
The recommended external bias resistor for HMC716LP3E at +5 V supply is 820 Ω, which sets the typical supply current to 65 mA. This value is specified in the Electrical Specifications table and validated in the "Typical Supply Current vs. Supply Voltage" plot. Using 820 Ω achieves the datasheet-typical 18 dB gain and +33 dBm OIP3. Deviations require re-characterization of linearity and noise performance.
Does HMC716LP3E require external DC blocking capacitors?
Yes, HMC716LP3E requires an external DC blocking capacitor on the RFIN pin (Pin 2), as this input is DC-coupled. The RFOUT pin (Pin 11) is AC-coupled and internally matched, so no output-side blocking capacitor is needed. Application Circuit diagrams confirm placement of a series capacitor at the input, typically 100 pF in 0402 package.
Can HMC716LP3E operate at +3 V supply, and what performance changes occur?
Yes, HMC716LP3E operates from +3 V to +5 V. At +3 V with 47 kΩ bias resistor, typical gain drops to 17 dB, OIP3 to +26 dBm, and NF remains ~1.3 dB. Supply current decreases to 41 mA, reducing power consumption but trading linearity-making it suitable for lower-power repeater or femtocell applications where interference density is moderate.
What is the thermal resistance and grounding requirement for HMC716LP3E?
HMC716LP3E has a channel-to-ground paddle thermal resistance of 90 °C/W. Its exposed ground paddle must be soldered to a solid PCB RF ground plane using multiple thermal vias. Notes in the Package Information section explicitly state: "ALL GROUND LEADS AND GROUND PADDLE MUST BE SOLDERED TO PCB RF GROUND." Failure to do so risks thermal runaway and gain instability.
Is HMC716LP3E pin-compatible with other Hittite LP3-series LNAs like HMC717LP3E?
No, HMC716LP3E is not pin-compatible with HMC717LP3E. While both use 3×3 mm QFN packages, their pin functions differ: HMC717LP3E uses Pin 8 for Vdd and Pin 15 for RES, whereas HMC716LP3E assigns Pin 8 to RES and Pin 15 to Vdd. The pinout table in the datasheet confirms this inversion, requiring PCB redesign for substitution.
