HMC284MS8GTR

RF Switches Overview

The HMC284MS8GTR is a Single Pole Double Throw (SPDT) RF switch IC manufactured by Analog Devices Inc. It operates from DC to 3.5 GHz with a typical insertion loss of 0.5 dB and typical isolation of 45 dB. The device features positive voltage control compatible with CMOS/TTL logic levels. It is housed in an ultra-small 8-lead grounded base MSOP package designed for surface mount applications.

RF Switches Feature Summary

• Non-reflective design optimized for high isolation and minimal insertion loss
• Positive voltage control operation compatible with standard logic levels
• Ultra-small 8-lead grounded base MSOP package for compact integration

RF Switches Applications

• Cellular and PCS base stations
• 2.4 GHz ISM band applications
• 3.5 GHz Wireless Local Loop systems

RF Switches Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration distinct from cut tape variants. Confirm RoHS compliance status as documentation may vary between 'HMC284MS8G' and 'HMC284MS8GE' designations. Ensure the ordered part matches the required lead frame and pinout specifications for the target PCB footprint.

RF Switches Selection Notes

Select this component for medium to low power RF switching applications requiring high isolation within the 3.5 GHz range. Consider the 8-lead MSOP package constraints for board space limitations. Verify that the positive control voltage requirements align with the system's logic supply rails before finalizing the design.

RF Switches Part Context

This component belongs to the HMC284A series of SPDT switches. It shares functional similarities with the HMC284AMS8G but differs in packaging and potential manufacturing revisions. The device is part of Analog Devices' portfolio of wireless and RF integrated circuits designed for communication infrastructure.

RF Switches Replacement Considerations

Direct substitutes include the HMC284MS8G and HMC284MS8GE. Verify pin compatibility and electrical parameter tolerances when substituting between these variants. Cross-reference datasheets to ensure identical package dimensions and thermal characteristics.
