HMC994LP5E

Overview

The HMC994LP5E is a GaAs MMIC distributed amplifier manufactured by Analog Devices Inc., designed for high-performance RF applications across the 0.01 GHz to 30 GHz frequency range. It delivers an output power of 0.5 W (27 dBm) and operates with a supply voltage of 5 V. The device features a gain of 18 dB, a noise figure of 6.5 dB, and a third-order intercept point (OIP3) of 32 dBm. Packaged in a compact 32-lead LFQFN (5x5 mm) surface-mount footprint, it supports operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated distributed amplifier topology providing wideband coverage from DC to 30 GHz
• High linearity performance with significant third-order intercept point for signal integrity
• Compact 32-lead LFQFN package optimized for dense surface-mount assembly

Applications

• VSAT communication systems requiring wideband amplification
• Electronic warfare and signal intelligence receivers
• Test and measurement instrumentation equipment

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm exact pinout and electrical characteristics, as variations exist between LP5E, PM5E, and reel options. Ensure compatibility with RoHS standards if required by your manufacturing process. Cross-reference the datasheet revision date to confirm current design parameters before finalizing procurement specifications.

Selection Notes

Select this component when a single-stage solution is needed for ultra-wideband amplification up to 30 GHz. Consider the 5V supply requirement and thermal dissipation capabilities inherent to the QFN package. Evaluate the trade-off between the 18 dB gain and the 6.5 dB noise figure against system-level link budget requirements compared to cascaded low-noise amplifier stages.

Part Context

This part belongs to the HMC994 family of MMICs, which are characterized by their distributed architecture suitable for broad frequency spans. While other variants like the HMC994A exist, the HMC994LP5E specifically denotes the leaded plastic quad flat no-lead package configuration. It serves as a core active element in high-frequency signal chains where consistent gain and phase response are critical.

Replacement Considerations

Public confirmed substitute part numbers include HMC994APM5ETR and HMC994APM5ETR-R5, which share the same functional specifications but differ in packaging or reel configuration. Verify that any alternative maintains the 32-LFQFN footprint and identical electrical parameters to ensure board-level compatibility.
