HMC450QS16GE

Overview

The HMC450QS16GE is a high-efficiency GaAs InGaP HBT medium power MMIC amplifier designed for operation between 800 and 1000 MHz. It delivers an output power of 26 dBm with a gain of 26 dB at 900 MHz. The device operates on a single 5 V supply, drawing 310 mA. It features a low noise figure of 8 dB and an input return loss of 17 dB. Power dissipation is rated at 0.5 W. The component is housed in a surface-mount QSOP-16 package.

Feature Summary

• Utilizes GaAs InGaP HBT technology for high efficiency and robust performance
• Provides significant signal amplification within the specified UHF frequency band
• Engineered for stable operation under standard single-supply voltage conditions

Applications

• UHF transmitter output stages
• Intermediate frequency amplification in communication systems
• General purpose RF signal boosting applications

Procurement Notes

Verify the specific suffix 'GE' to confirm RoHS compliance status as indicated by manufacturer documentation. Confirm the QSOP-16 package dimensions against PCB footprint requirements prior to integration. Ensure thermal management strategies account for the specified power dissipation limits during continuous operation.

Selection Notes

Select this component when a medium power amplification solution is required within the 800 to 1000 MHz range. Consider the 26 dB gain and 26 dBm output power capabilities relative to system linearity requirements. Evaluate the 310 mA current draw against available power budget constraints for portable or battery-operated designs.

Part Context
