HMC903LP3E

Overview

The HMC903LP3E is a GaAs pHEMT MMIC low-noise amplifier operating from 6 GHz to 17 GHz. It provides 18.5 dB small-signal gain and a 1.7 dB noise figure in the 6–16 GHz range. The device delivers 25 dBm output IP3 and 14.5 dBm P1dB compression point across the full band. Powered by a single 3.5 V supply, it consumes 80 mA. Integrated DC blocking and 50 Ω matching simplify circuit design.

Feature Summary

• Utilizes self-biased GaAs pHEMT technology with optional bias control for reduced quiescent current
• Features integrated DC blocking on input and output ports with internal 50 Ω impedance matching
• Supports direct cascading without external matching circuits due to stable impedance characteristics

Applications

• Point-to-point microwave radio systems
• Military and space communication equipment
• Video satellite (VSAT) receiving terminals
• Test and measurement instrumentation

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status and check for recent Product Change Notifications (PCN). Ensure storage conditions meet moisture sensitivity level requirements prior to surface mount reflow processing.

Selection Notes

Select this component for wideband applications requiring high linearity and low noise between 6 GHz and 17 GHz. The 16-pin LFCSP package suits compact designs. Ensure PCB layout provides low-inductance ground connections to GND pins and the exposed pad for optimal thermal and RF performance stability.

Part Context

Manufactured by Analog Devices Inc., the HMC903LP3E belongs to the HMC903G series of monolithic microwave integrated circuits. It represents a specialized solution for high-frequency signal chain applications where minimal noise degradation and high dynamic range are critical system requirements.
