Product details
Overview
HMC374SC70E from Analog Devices is a GaAs pHEMT low-noise amplifier operating from 0.3 to 3.0 GHz, delivering 15 dB gain at 0.6 GHz, 1.6 dB noise figure, +17 dBm P1dB, and +35 dBm OIP3 from a +3.3 V single supply - used in cellular/PCS/3G front-end receive chains.
For engineers reviewing the HMC374SC70E datasheet, HMC374SC70E pinout, HMC374SC70E application, or HMC374SC70E equivalent, key selection criteria include broadband LNA performance across 0.3–3 GHz, SC70E package footprint constraints, thermal stability over –40°C to +85°C, and RF input/output matching requirements for 50 Ω systems.
Technical Context
The HMC374SC70E employs a monolithic GaAs pHEMT process optimized for low-noise, high-linearity RF amplification. Its internal bias network enables stable operation with only external DC blocking and RF matching components.
It operates over –40°C to +85°C with gain variation ≤0.012 dB/°C (–40°C to +25°C) and noise figure variation ≤0.6 dB across temperature and frequency. Input and output return loss exceed 6 dB and 8 dB respectively across 0.3–3 GHz at +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 0.3–3.0 GHz - supports full-band cellular/PCS/WCS/ISM/WLAN receive paths without tuning. |
| Gain | 15 dB @ 0.6 GHz - provides sufficient signal boost before mixer or ADC in low-SNR front ends. |
| Noise Figure | 1.6 dB @ +25°C - minimizes system noise contribution in sensitive receiver stages. |
| OIP3 | +35 dBm - enables robust interference rejection in crowded spectral environments (e.g., base station co-location). |
| P1dB | +17 dBm - supports high-dynamic-range operation with >20 dB input-referred compression margin. |
| Supply Voltage | +3.0 to +3.6 V - compatible with standard 3.3 V rail; current draw fixed at 75 mA across voltage range. |
| Operating Temp | –40°C to +85°C - qualified for industrial and outdoor wireless infrastructure deployment. |
Pinout & Package
Package: SC70E (6-lead, 0.089" × 0.053", RoHS-compliant low-stress molded plastic; MSL1; matte tin plating).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | N/C | May be grounded for mechanical stability; no electrical function - no impact on RF performance. |
| 2, 5 | GND | RF/DC ground terminals - must connect directly to PCB ground plane via multiple vias for impedance control. |
| 3 | IN | DC-coupled RF input - requires external DC blocking capacitor; matched to 50 Ω at RF. |
| 6 | OUT | RF output and DC bias node - supplies drain voltage to output stage; requires external RF choke and bypassing. |
Key Features
| Feature | Design Value |
|---|---|
| Broadband 0.3–3.0 GHz operation | Eliminates need for band-select filters or tunable matching in multi-standard receivers. |
| 1.6 dB noise figure @ 0.6 GHz | Enables high sensitivity in sub-1 GHz cellular bands where path loss dominates. |
| +35 dBm OIP3 with +17 dBm P1dB | Supports simultaneous reception of strong interferers and weak signals in dense RF environments. |
| SC70E package (2.26 mm × 1.35 mm) | Reduces PCB area by >50% vs. SOT-23 while maintaining thermal resistance of 205 °C/W. |
| Single +3.3 V supply, 75 mA IDD | Simplifies power design - no negative rails or bias sequencing required. |
Applications
| Cellular Base Station Receiver | WLAN 2.4 GHz Front End |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC468LP3E | Higher frequency range (2–12 GHz), higher NF (2.0 dB @ 2 GHz), same SC70E package. | Optimized for microwave backhaul and test equipment, not sub-3 GHz cellular bands. | Select when extending coverage beyond 3 GHz; avoid for 0.3–3 GHz cost-sensitive designs. |
| QPL9057 | 0.6–6.0 GHz range, 0.65 dB NF @ 2.4 GHz, 3.3 V supply, 55 mA IDD, 2×2 mm DFN. | Lower power, smaller package, but lower OIP3 (+29 dBm) limits use in high-interference base stations. | Prefer for battery-powered WLAN clients; insufficient linearity for macrocell BTS deployment. |
Compared with HMC374SC70E, HMC468LP3E trades bandwidth extension for reduced low-band NF performance, while QPL9057 offers lower power and size at the expense of third-order linearity - making HMC374SC70E optimal for cost-constrained, high-linearity 0.3–3 GHz infrastructure LNA roles.

FAQ
What is the recommended DC blocking capacitor value for the HMC374SC70E input?
A 27 pF capacitor (0402 package) is specified in the official evaluation board design (EVAL01-HMC374SC70E) for the HMC374SC70E input. This value ensures effective DC isolation while maintaining broadband 50 Ω match across 0.3–3 GHz; larger values risk degrading high-frequency return loss.
Does the HMC374SC70E require external bias sequencing?
No, the HMC374SC70E does not require external bias sequencing. It operates from a single +3.0 to +3.6 V supply with fixed 75 mA current draw - no startup delay, no gate voltage ramping, and no separate VGS control needed. The internal bias network ensures stable turn-on across temperature.
Can the HMC374SC70E be used in 5 V supply systems?
No - the absolute maximum drain bias voltage for the HMC374SC70E is +7.0 Vdc, but its specified operating range is strictly +3.0 to +3.6 V. Operation at 5 V exceeds recommended conditions and risks permanent degradation of GaAs pHEMT characteristics; no performance data is provided for 5 V operation.
What is the thermal resistance (θJL) of the HMC374SC70E package?
The HMC374SC70E has a channel-to-lead thermal resistance (θJL) of 205 °C/W, measured per JEDEC JESD51-14. This value assumes all ground pins (2 and 5) are soldered to a solid PCB ground plane with ≥6 thermal vias - critical for sustaining 0.32 W continuous dissipation at TA = 85 °C.
Is the HMC374SC70E ESD-protected, and what is its HBM rating?
Yes, the HMC374SC70E is classified as Class 0 per JEDEC JS-001 HBM ESD specification (<250 V). It requires strict handling precautions: grounded wrist straps, conductive foam storage, and ionized air workstations - especially during manual PCB placement or rework.
