HMC253ALC4TR-R5

RF Switches Overview

The HMC253ALC4TR-R5 is a non-reflective single-pole eight-throw (SP8T) radio frequency switch manufactured by Analog Devices Inc. It operates from DC to 3.5 GHz with an insertion loss of 1.1 dB and typical off-isolation of 43 dB. The device utilizes GaAs technology in a 24-TFCQFN package, supporting 50 Ohm impedance. It functions on a 5 V supply with 4.5 mA current consumption, switching within 100 ns.

RF Switches Feature Summary

• Non-reflective SP8T topology for signal routing
• Wideband operation covering DC to 3.5 GHz
• Low power consumption suitable for portable systems

RF Switches Applications

• WiMax infrastructure equipment
• Wireless local loop systems
• Test and measurement instrumentation

RF Switches Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance and moisture sensitivity level requirements during storage and handling. Ensure proper ESD precautions are applied during assembly. Cross-reference datasheet revisions to confirm electrical parameters match design specifications before finalizing procurement orders.

RF Switches Selection Notes

Select this component for applications requiring wideband RF switching up to 3.5 GHz. Consider the 24-TFCQFN package size for space-constrained designs. Evaluate thermal management needs given the surface mount installation style. Compare isolation and insertion loss metrics against system requirements to ensure signal integrity across the specified frequency range.

RF Switches Part Context

This part belongs to the HMC253 series of RF switches. It shares functional similarities with models like HMC253LC4TR but differs in specific packaging and manufacturing process details. The LC4 variant is obsolete, making the AL4 series the primary active alternative within the product line for similar performance characteristics.

RF Switches Replacement Considerations

HMC253ALC4 serves as a direct equivalent replacement option.
