HMC694-SX

RF Amplifiers Overview

The HMC694-SX is a GaAs MMIC pHEMT analog variable gain amplifier die operating between 6 and 17 GHz. It provides a typical gain of 22 dB with a noise figure of 6 dB. The device features a P1dB compression point of 21 dBm and an OIP3 of 30 dBm. It operates on a 5 V supply with a current draw of 170 mA. The input return loss is 15 dB, and power dissipation is 920 mW.

RF Amplifiers Feature Summary

• Analog variable gain control capability for microwave radio applications
• GaAs MMIC pHEMT technology construction
• High linearity performance with 30 dBm OIP3

RF Amplifiers Applications

• Microwave radio systems
• Point-to-point communication links

RF Amplifiers Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm the exact die configuration and testing parameters. Ensure that the procurement channel provides valid traceability for this component type. Confirm compatibility with the intended RF circuit design before acquisition.

RF Amplifiers Selection Notes

Select this component for designs requiring wideband analog gain adjustment in the 6 to 17 GHz range. Consider the 5 V supply requirement and 170 mA current consumption during power budgeting. Evaluate the thermal management needs given the 920 mW power dissipation specification for the bare die format.

RF Amplifiers Part Context

This part belongs to the HMC694 series of variable gain amplifiers from Analog Devices. It represents the bare die version (SX) of the HMC694LP4E packaged variant. The series utilizes GaAs pHEMT technology to deliver high-performance RF amplification suitable for demanding microwave frequencies.

RF Amplifiers Replacement Considerations

The HMC694LP4E is the packaged equivalent of this die. Verify if the system design can accommodate the SMD/SMT QFN-24 package instead of the bare die form factor.
