HMC375LP3E vs HMC382LP3E Specifications

HMC375LP3E: Better for Maximum RF Performance

The HMC375LP3E is the stronger choice when receiver sensitivity and linearity are the main priorities.

Its key advantages include:

0.9dB typical noise figure

Approximately 17dB gain

Up to approximately +34dBm OIP3

Stable gain over supply voltage and temperature

+5V operation

The trade-off is higher current consumption of approximately 136mA at 5V.

Best Fit

HMC375LP3E is particularly suitable when the legacy design requires:

Low noise + high linearity + strong interference handling

Typical applications include GSM, GPRS, EDGE, CDMA, W-CDMA and DECT receiver systems.

HMC382LP3E: Better for Adjustable Power Consumption

The HMC382LP3E provides similar frequency coverage and gain but uses a different bias architecture.

Its main advantage is externally adjustable supply current.

At a typical operating point around 67mA, the device provides approximately:

17dB gain

1.0dB noise figure

+30dBm output IP3

Changing the bias current allows designers to trade current consumption against gain, linearity and other RF performance parameters.

Best Fit

HMC382LP3E is more attractive when the design requires:

Lower power consumption + adjustable bias + 50Ω matched RF interfaces

Typical applications include cellular/3G infrastructure, base stations, repeaters and legacy GSM/CDMA systems.

Are HMC375LP3E and HMC382LP3E Interchangeable?

They should not automatically be treated as pin-to-pin replacements.

Although both cover the same frequency range and use compact 3mm × 3mm packages, differences include:

Bias architecture

Supply current

Input matching

OIP3

Noise figure

Pin configuration

PCB matching requirements

A replacement should therefore be verified against the original schematic, layout and RF performance requirements.
