Product details
Overview
HMC616LP3 from Hittite Microwave Corporation is a GaAs PHEMT MMIC low-noise amplifier optimized for cellular/3G and LTE/WiMAX/4G base station front-end receivers operating from 175–660 MHz. It delivers 0.5 dB noise figure, 24 dB gain at +5 V, and +37 dBm output IP3 with 50 Ω input/output matching and single-supply operation from +3 V to +5 V.
For engineers reviewing the HMC616LP3 datasheet, HMC616LP3 pinout, HMC616LP3 application, or HMC616LP3 equivalent, key selection criteria include its ultra-low noise figure across wide bandwidth, externally adjustable bias current via Rbias, excellent input/output return loss (>10 dB), and compatibility with infrastructure-grade thermal and RF layout requirements.
Technical Context
The HMC616LP3 employs a monolithic GaAs PHEMT process to achieve sub-0.6 dB noise figure while maintaining high linearity (IP3 ≥ +37 dBm) in a compact 3×3 mm QFN. Its bias architecture uses an external resistor on Pin 8 (RES) to set supply current between 30–115 mA, enabling trade-off tuning of noise, gain, and linearity per application.
It operates over –40°C to +85°C with integrated thermal management via exposed ground paddle (θJA = 112°C/W). Input and output are internally matched to 50 Ω, minimizing external components-only DC blocking capacitors, choke inductor, bypass caps, and Rbias are required per the application circuit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise Figure | 0.5 dB typical @ 25°C - enables high sensitivity in weak-signal receiver front-ends |
| Small-Signal Gain | 24 dB typical @ 400 MHz, +5 V - provides sufficient LNA gain to overcome downstream stage noise |
| Output IP3 | +37 dBm typical @ 400 MHz, +5 V - supports high dynamic range in multi-carrier cellular base stations |
| P1dB Output Power | +15 dBm typical @ 400 MHz, +5 V - ensures linear operation under typical signal compression thresholds |
| Supply Voltage Range | +3 V to +5 V - allows flexible system-level power rail selection without redesign |
| Input/Output Impedance | 50 Ω matched - eliminates need for external matching networks in standard RF layouts |
| Operating Frequency | 175–660 MHz - covers DCS, PCS, AWS, LTE Bands 13/14/17/25/26/66, and public safety UHF |
Pinout & Package
Package: 16-lead 3×3 mm QFN with exposed ground paddle (MSL1, Sn/Pb finish for HMC616LP3); RoHS-compliant matte Sn for HMC616LP3E. Ground paddle must be soldered to PCB RF ground per Hittite land pattern guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3–5, 7, 9, 10, 12–14, 16 | No Connection | Internally unused; may be grounded without performance impact |
| 2 | RFIN | DC-coupled RF input requiring external DC blocking capacitor |
| 6 | GND | Dedicated ground terminal; must connect to RF/DC ground alongside exposed paddle |
| 8 | RES | Bias current control node - external Rbias (e.g., 3.92 kΩ) sets Idd and optimizes NF/IP3 trade-off |
| 11 | RFOUT | 50 Ω matched RF output - minimal external filtering needed for broadband use |
| 15 | Vdd | Positive supply input - requires choke inductor and multi-stage bypassing (C1–C3) |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise figure | 0.5 dB typical enables detection of weak signals in crowded spectral environments |
| Externally adjustable bias | Rbias-controlled Idd allows real-time optimization of NF vs. IP3 for specific band/channel loading |
| Wideband 50 Ω match | Input/output return loss >10 dB across 175–660 MHz reduces design iteration and layout risk |
| Thermally robust QFN | Exposed paddle + 112°C/W θJA supports continuous operation at +85°C ambient in sealed enclosures |
| Multi-voltage operation | Stable performance from +3 V to +5 V simplifies integration into mixed-rail base station subsystems |
Applications
| Cellular Base Station Front-End | LTE/WiMAX Infrastructure Receiver |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC617LP3 | Same 3×3 mm QFN package and pinout; 0.6 dB NF, 23 dB gain, +35 dBm IP3 @ 400 MHz | Slightly higher NF and lower IP3; optimized for narrower 200–400 MHz range | Prefer HMC616LP3 when lowest possible NF or wider 175–660 MHz coverage is required |
| HMC618LP3 | Same footprint and pinout; 0.7 dB NF, 22 dB gain, +33 dBm IP3 @ 400 MHz; lower Idd (25 mA @ +3 V) | Lower power consumption but reduced linearity; suited for battery-backed or thermally constrained nodes | Choose HMC616LP3 for infrastructure-grade linearity; HMC618LP3 for portable or low-power repeater designs |

FAQ
What is the recommended Rbias value for HMC616LP3 at +5 V supply?
The recommended Rbias for HMC616LP3 at +5 V is 3.92 kΩ, yielding ~91 mA supply current, 0.5 dB noise figure, and +37 dBm IP3 at 400 MHz. This value balances optimal noise performance with high linearity and is validated in the Hittite application circuit and electrical specifications table.
Does HMC616LP3 require external matching components?
HMC616LP3 features internally matched 50 Ω input and output ports, so no external matching networks are required. Only essential support components are needed: DC blocking capacitor at RFIN (Pin 2), choke inductor and bypass capacitors at Vdd (Pin 15), and Rbias at RES (Pin 8).
Can HMC616LP3 operate at +3 V, and how does performance change?
Yes, HMC616LP3 operates from +3 V to +5 V. At +3 V with 3.92 kΩ Rbias, Idd drops to ~31 mA, reducing gain to ~21 dB and IP3 to ~+32 dBm, while maintaining 0.5 dB NF. This enables low-power modes for portable or thermally limited applications.
What is the thermal resistance and maximum channel temperature for HMC616LP3?
HMC616LP3 has a channel-to-ground-paddle thermal resistance (θJG) of 112°C/W. Its absolute maximum channel temperature is 150°C, with rated operating junction temperature up to 125°C. The exposed paddle must be soldered to a solid RF ground plane with multiple vias for effective heat dissipation.
Is HMC616LP3 pin-compatible with other LP3-series LNAs?
Yes, HMC616LP3 shares identical 16-lead 3×3 mm QFN package dimensions and pinout with HMC617LP3 and HMC618LP3, enabling drop-in replacement in existing layouts-provided bias and decoupling networks are verified for the target performance point.
