HMC452QS16GE

Overview

The HMC452QS16GE is a high dynamic range GaAs InGaP HBT MMIC power amplifier from Analog Devices Inc. It operates in the 0.4 to 2.2 GHz frequency range with a typical gain of 9 dB and a noise figure of 7.5 dB. The device delivers 1 Watt output power, featuring a P1dB compression point of 31 dBm and an OIP3 of 48 dBm. It requires a 5 V supply voltage and draws 485 mA operating current. Packaged in a QSOP-16 surface-mount format, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes GaAs InGaP Heterojunction Bipolar Transistor (HBT) technology for high dynamic range performance
• Provides 1 Watt output power capability across a broad 0.4 to 2.2 GHz bandwidth
• Designed for surface-mount integration using a compact QSOP-16 package

Applications

• Wireless infrastructure base station front-end modules
• Point-to-point microwave radio systems
• Test and measurement equipment requiring high linearity

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix 'GE' matches project requirements, as it denotes lead-free status and RoHS compliance. Check current lifecycle status, as availability may vary by region. Ensure thermal management solutions align with the specified 2.7 W power dissipation rating during operation.

Selection Notes

Select this component when a single-chip solution is needed for moderate power amplification between 400 MHz and 2.2 GHz. It is suitable for designs prioritizing high IP3 and P1dB metrics over ultra-low noise applications. Consider the 5 V supply requirement and 485 mA current draw for power budget calculations. The QSOP-16 package is appropriate for standard SMT assembly processes.
