Product details
Overview
HMC311LP3 from Analog Devices is a GaAs InGaP HBT MMIC gain block amplifier operating from DC to 6 GHz, delivering 14.5 dB small-signal gain, +15.5 dBm P1dB output power, and +32 dBm output IP3 at +5 V supply with 56 mA quiescent current. It serves as a cascadable 50 Ω gain stage or LO driver for mixers in RF front-ends.
For engineers reviewing the HMC311LP3 datasheet, HMC311LP3 pinout, HMC311LP3 application, or HMC311LP3 equivalent, this page provides verified specifications, thermal stability data, biasing guidance, package layout, and real-world RF design context for cellular, microwave radio, and WLAN signal chain integration.
Technical Context
The HMC311LP3 employs a Darlington feedback pair architecture using InGaP HBT technology, enabling stable gain over temperature (±0.016 dB/°C max) and reduced process sensitivity. Its monolithic construction integrates all active and passive elements on a single GaAs die.
It features DC-coupled RFIN (Pin 3), RFOUT with integrated DC bias feed (Pin 10), and 14 no-connect pins (1,2,4–9,11–16) designed for grounding. The exposed paddle must be soldered to RF/DC ground for thermal and electrical performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 6 GHz - supports broadband amplification without tuning across cellular, WLAN, and microwave bands. |
| Small-Signal Gain | 14.5 dB typical - enables single-stage gain boosting in cascaded RF paths with minimal external components. |
| P1dB Output Power | +15.5 dBm @ 1 GHz - sufficient to drive mixer LO ports or serve as final IF/LNA stage in compact transceivers. |
| OIP3 | +32 dBm @ DC–1 GHz - ensures low intermodulation distortion in multi-carrier systems like LTE base stations. |
| Noise Figure | 4.5 dB @ DC–6 GHz - balances linearity and noise for receiver front-end applications requiring moderate sensitivity. |
| Supply Current | 56 mA @ +5 V - enables low-power operation while maintaining high dynamic range and thermal stability. |
| Input/Output Impedance | 50 Ω matched - simplifies PCB layout with no external matching required for standard RF interfaces. |

Package: 16-lead LFCSP (Lead Frame Chip Scale Package), 3 mm × 3 mm body, 0.85 mm height, exposed thermal paddle (JEDEC MO-220-VEED-4, CP-16-50). RoHS-compliant Sn finish available as HMC311LP3E.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 3 | RFIN | DC-coupled RF input requiring external blocking capacitor; optimized for 50 Ω source impedance. |
| Pin 10 | RFOUT | RF output with integrated DC bias feed; requires external blocking capacitor and 50 Ω load termination. |
| Pins 1,2,4–9,11–16 | N/C | No-connect terminals; recommended to connect directly to RF/DC ground for shielding and thermal conduction. |
| Exposed Paddle | GND | Primary thermal and RF ground path; must be soldered to solid ground plane with multiple vias for <192 °C/W junction-to-board thermal resistance. |
Key Features
| Feature | Design Value |

FAQ
What is the recommended bias resistor value for HMC311LP3 to achieve nominal Icc?
The HMC311LP3 requires an external bias resistor (Rbias) connected to Pin 10 (RFOUT) to set quiescent current. Using the formula Icc = (Vs − 3.8 V) / Rbias, a 22 Ω resistor yields ~56 mA at +5 V supply. Values ≥22 Ω are acceptable; lower values increase current but risk exceeding 74 mA absolute maximum.
Does HMC311LP3 require external DC blocking capacitors?
Yes, the HMC311LP3 requires external DC blocking capacitors on both RFIN (Pin 3) and RFOUT (Pin 10). Pin 3 is DC-coupled and must be isolated from preceding stage DC bias; Pin 10 supplies DC bias to the output transistor and must isolate that voltage from the next stage's input.
What is the thermal resistance and maximum power dissipation of HMC311LP3?
The HMC311LP3 has a junction-to-ground-paddle thermal resistance of 192 °C/W. At +85 °C ambient, it supports 0.339 W continuous power dissipation; above 85 °C, derate by 5.21 mW/°C. Proper soldering of the exposed paddle to a multivias ground plane is essential to achieve this rating.
Is HMC311LP3 pin-compatible with HMC311LP3E?
Yes, HMC311LP3 and HMC311LP3E share identical pinout, footprint, and electrical specifications. The only difference is lead finish: Sn/Pb for HMC311LP3 and 100% matte Sn for RoHS-compliant HMC311LP3E, with corresponding reflow profile differences (235 °C vs. 260 °C peak).
Can HMC311LP3 operate below 100 MHz, including true DC coupling?
Yes, the HMC311LP3 is specified from DC to 6 GHz. Its DC-coupled RFIN (Pin 3) supports baseband and low-IF applications down to 0 Hz, provided external blocking is managed appropriately and input signal DC offset remains within ±0.5 V to avoid forward-biasing internal junctions.
