Product details
Overview
HMC451LP3 from Analog Devices is a GaAs PHEMT MMIC medium power amplifier operating from 5 to 18 GHz, delivering 18 dB gain, +21 dBm saturated output power at 18% PAE, and +28 dBm output IP3 under +5 V/120 mA bias - ideal as a linear gain block or LO driver for HMC mixers in microwave radio and test equipment.
For engineers reviewing the HMC451LP3 datasheet, HMC451LP3 pinout, HMC451LP3 application, or HMC451LP3 equivalent, this page provides verified RF performance data, 16-pin LFCSP package details, temperature-stable S-parameter behavior, and validated alternatives for 5–18 GHz broadband amplification design.
Technical Context
The HMC451LP3 integrates a two-stage GaAs PHEMT amplifier with fully 50 Ω matched RF input (Pin 3) and output (Pin 10), both DC-blocked. It operates from a single +5 V supply applied to Pins 13 (Vdd2) and 15 (Vdd1), requiring external bypassing with 100 pF, 1000 pF, and 2.2 µF capacitors per supply rail.
Its broadband operation across 5–18 GHz is enabled by internal matching networks eliminating external components; gain flatness, return loss (≥12 dB input, ≥8 dB output), and compression characteristics (P1dB = 19.5 dBm typ.) are specified over −40°C to +85°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 5–18 GHz - supports full-band operation without tuning in microwave radio, VSAT, and test instrumentation. |
| Small-Signal Gain | 18 dB typ. - enables single-stage gain boosting with minimal cascading in receiver front-ends or LO chains. |
| Saturation Power (Psat) | +21 dBm @ 18% PAE - delivers usable RF output into 50 Ω with defined efficiency at high drive levels. |
| OIP3 | +28 dBm - ensures low intermodulation distortion in multi-tone or wideband signal environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar medium-power broadband amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC451LP3E | RoHS-compliant variant with 100% matte tin finish; identical electrical specs and pinout; MSL1 rating with 260 °C peak reflow. | Required for lead-free manufacturing; same RF performance but different solder alloy compatibility. | Select HMC451LP3E when RoHS compliance and Pb-free assembly are mandatory. |
| HMC441LP3 | Lower frequency range (3–12 GHz); 20 dB gain; +19 dBm Psat; same 3×3 mm LFCSP package and +5 V bias. | Better suited for sub-12 GHz infrastructure where extended upper band is unnecessary. | Choose HMC441LP3 for cost-sensitive, lower-frequency designs where 18 GHz capability is unused. |
Compared with HMC451LP3, the HMC451LP3E offers identical RF performance with RoHS-compliant packaging, while the HMC441LP3 trades upper-band coverage for higher gain and marginally lower power - enabling optimized selection based on frequency requirement and environmental compliance.

FAQ
What is the operating frequency range of the HMC451LP3?
The HMC451LP3 operates from 5 to 18 GHz, with verified gain, return loss, and compression performance across the full band. Typical gain is 18 dB, and saturated output power remains ≥+21 dBm throughout this range, making the HMC451LP3 suitable for wideband microwave applications including VSAT and test instrumentation.
Does the HMC451LP3 require external matching components?
No, the HMC451LP3 features fully 50 Ω matched RF input (Pin 3) and output (Pin 10), both AC-coupled, eliminating the need for external matching networks or DC blocking capacitors. This simplifies layout and reduces bill-of-materials cost while maintaining broadband performance - a key design advantage of the HMC451LP3.
What supply voltage and current does the HMC451LP3 need?
The HMC451LP3 operates from a single +5 V supply applied to Pins 13 (Vdd2) and 15 (Vdd1), drawing 120 mA typical at +25°C. Absolute maximum drain voltage is +5.5 V. External bypassing with 100 pF, 1000 pF, and 2.2 µF capacitors per rail is required to ensure stability - a critical implementation detail for reliable HMC451LP3 operation.
How is thermal management handled on the HMC451LP3?
The HMC451LP3 uses an exposed thermal paddle that must be soldered to a solid RF/DC ground plane. Its thermal resistance is 78 °C/W (channel-to-ground), and continuous power dissipation is rated at 1.15 W at 85°C ambient (derated above). Proper grounding of the exposed pad is essential for both thermal performance and RF return path integrity in the HMC451LP3.
Is the HMC451LP3 pin-compatible with other HMC amplifiers?
The HMC451LP3 uses a proprietary 16-lead 3×3 mm LFCSP package (HCP-16-1) and is not pin-compatible with other HMC amplifiers such as the HMC441LP3 or HMC564LP3, despite shared package dimensions. Pin functions - including dual Vdd inputs and specific N/C assignments - are unique to the HMC451LP3 and must be verified against its official pinout diagram before board reuse.
