Description: 1.7–2.2GHz high-dynamic-range GaAs pHEMT LNA with adjustable supply current
The HMC382LP3E is a high-dynamic-range RF low noise amplifier optimized for cellular base-station and wireless infrastructure receivers.
Its combination of low noise, useful gain and high linearity makes it suitable for receiver front ends exposed to strong adjacent-channel signals.
Key characteristics include:
1.7GHz to 2.2GHz frequency range
17dB typical gain
1.0dB typical noise figure
+30dBm output IP3
Single +5V supply
Adjustable bias current
Internally matched 50Ω input and output
The adjustable supply current allows designers to trade power consumption against linearity according to system requirements.

HMC382LP3E Replacement
There is no universal pin-to-pin replacement for HMC382LP3E.
The original documentation suggests HMC618LP3(E) for applications requiring improved noise figure, but lifecycle status and circuit compatibility must be checked before considering any alternative.
Important replacement parameters include:
Frequency range
Gain
Noise figure
OIP3
Supply current
Bias architecture
Input/output matching
Package footprint
For new designs, a currently supported Analog Devices RF LNA should generally be selected instead of another obsolete Hittite device.
