HMC245AQS16ETR

RF Switches Overview

The HMC245AQS16ETR is a GaAs pHEMT MMIC SP3T non-reflective RF switch from Analog Devices Inc., operating from DC to 3.5 GHz in a 16-QSOP package. It features an insertion loss of 0.8 dB and isolation of 36 dB at 2.5 GHz. The device supports a 5 V supply with a typical current of 2.5 mA. Key performance metrics include a P1dB of 29 dBm and an IIP3 of 48 dBm within the 0.3–3.5 GHz range. Switching times are typically 40 ns, with a maximum run time of 150 ns. It operates between -40°C and +85°C.

RF Switches Feature Summary

• Integrates a 2:4 decoder for simplified control using only two lines and a single positive bias voltage.
• Provides true TTL/CMOS compatibility for direct interface with standard logic controllers.
• Utilizes GaAs pHEMT technology to achieve low insertion loss and high linearity.

RF Switches Applications

• CATV and DBS signal distribution systems
• Wireless local loop infrastructure
• Base station and portable wireless equipment
• RF test and measurement devices

RF Switches Procurement Notes

Verify the specific suffix 'QS16' confirms the 16-lead QSOP package variant. Ensure the order matches the 'ETR' designation for tape and reel packaging if automated assembly is required. Confirm RoHS3 compliance status for environmental regulations. Cross-reference the manufacturer part number HMC245AQS16E with distributor codes to avoid substitution errors.

RF Switches Selection Notes

Select this component for applications requiring a single-pole triple-throw configuration up to 3.5 GHz. It is suitable where low control complexity is prioritized over multi-path switching density. Consider the 16-QSOP footprint for space-constrained PCB layouts. Evaluate the 2.5 mA supply current against power budget constraints for battery-operated or low-power systems.

RF Switches Part Context

This part belongs to the HMC245 series of non-reflective RF switches designed by Analog Devices. It shares architectural similarities with the HMC241 but differs in topology, offering SP3T rather than SP4T switching. The series targets cost-effective solutions for CATV and wireless infrastructure markets, leveraging mature GaAs MMIC processes for reliable high-frequency performance.

RF Switches Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility before considering alternative SP3T switches from other manufacturers. Check frequency range and package dimensions to ensure mechanical fit.
