HMC241AQS16TR

RF Switches Overview

The HMC241AQS16TR is a GaAs MMIC SP4T non-reflective RF switch from Analog Devices, operating from DC to 3.5 GHz. It features integrated 2:4 decoding for TTL/CMOS compatibility using only two control lines and a single positive bias. Key electrical parameters include a typical insertion loss of 0.8 dB at 2.5 GHz, isolation of 36 dB, P1dB of 29 dBm, and IIP3 of 48 dBm. It operates on a 5 V supply with 2.5 mA current consumption, supports -40°C to +85°C temperatures, and is housed in a 16-QSOP package.

RF Switches Feature Summary

• Integrates 2:4 decoder to reduce control line requirements to two inputs
• Provides true TTL/CMOS logic compatibility with single positive bias voltage
• Delivers non-reflective signal path performance across wide frequency range

RF Switches Applications

• Base station infrastructure
• CATV and DBS systems
• Wireless local loop equipment
• Portable wireless devices

RF Switches Procurement Notes

Verify the specific suffix ETR against official Analog Devices documentation to confirm reel packaging specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region and production cycle.

RF Switches Selection Notes

Select this component when designing circuits requiring simplified control logic for SP4T switching. The integrated decoder eliminates external logic gates. Ensure the design accommodates the 5 V supply requirement and QSOP-16 thermal constraints for reliable operation in CATV or wireless environments.

RF Switches Part Context

This device belongs to the HMC241 series of low-cost, general-purpose RF switches. It utilizes Gallium Arsenide (GaAs) technology to achieve high linearity and low loss. The part is designed to replace traditional GaAs SP4T switches that typically require multiple control lines and complex biasing networks.

RF Switches Replacement Considerations

Check for direct pin-compatible alternatives within the Analog Devices portfolio if supply constraints exist. Verify that any substitute maintains the same 16-QSOP footprint and 3.5 GHz operational bandwidth.
