HMC7911LP5E

Overview

The HMC7911LP5E is a GaAs MMIC up-converter designed for the 17.5 GHz to 19.7 GHz RF frequency range. It features an integrated variable gain amplifier (VGA) and operates with an intermediate frequency (IF) from 0 Hz to 3.5 GHz and a local oscillator (LO) frequency of 7.1 GHz to 11.6 GHz. The device provides a small signal conversion gain of 14 dB, a noise figure of 22 dB, and an OIP3 of 31 dBm. It requires dual power supplies of 3.3 V and 5 V, drawing currents of 110 mA and 225 mA respectively, with a maximum power dissipation of 1.7 W. Packaged in a QFN-32 surface-mount package, it supports operation between -40°C and +85°C.

Feature Summary

• Integrates a VGA preceding the mixer stage for flexible signal level control
• Provides high sideband rejection of 30 dBc for improved spectral purity
• Utilizes robust GaAs technology for reliable high-frequency performance

Applications

• Point-to-point microwave radio links
• Satellite communication ground stations
• Electronic warfare systems requiring wide bandwidth

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Request official datasheets and test reports to confirm compliance with RoHS standards and material declarations. Inspect packaging integrity upon receipt to prevent damage to the sensitive QFN-32 exposed pad structure. Ensure supply chain documentation matches the specific LP5E suffix to avoid receiving non-compliant variants.

Selection Notes

Evaluate thermal management requirements carefully due to the 1.7 W power dissipation specification within the compact QFN-32 footprint. Confirm that the system's IF and LO frequencies fall strictly within the specified operational ranges to ensure proper mixing functionality. Consider the impact of the 22 dB noise figure on overall link budget calculations. Verify that the required gain adjustment capabilities of the internal VGA meet the dynamic range needs of the application.
