HMC253AQS24

RF Switches Overview

The HMC253AQS24 is a low-cost, non-reflective Single-Pole-8-Throw (SP8T) RF switch manufactured by Analog Devices Inc. It operates over a wideband frequency range from DC to 2.5 GHz and is housed in a 24-lead QSOP package. The device features an absorption topology with 50 Ohm impedance. Key electrical specifications include a typical insertion loss of 1 dB, isolation of 40 dB, P1dB of 23 dBm, and IIP3 of 46 dBm. It requires a 5V supply voltage and supports single positive bias with true TTL/CMOS compatibility.

RF Switches Feature Summary

• Non-reflective SP8T switching architecture for signal routing
• Wideband operation covering DC to 2.5 GHz frequencies
• Single positive bias configuration with TTL/CMOS control compatibility

RF Switches Applications

• CDMA wireless communication systems
• RF signal chain routing in test and measurement equipment
• Broadband antenna switching applications

RF Switches Procurement Notes

Verify the specific suffix when ordering; E denotes an enhanced or alternative version, while TR indicates tape and reel packaging. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the 24-QSOP footprint matches your PCB design constraints before finalizing procurement.

RF Switches Selection Notes

Select this component for applications requiring high isolation and low reflection across a broad DC-to-2.5 GHz bandwidth. The single positive bias simplifies control logic integration compared to dual-bias alternatives. Consider the 24-QSOP package size relative to available board space and thermal management needs for the target environment.

RF Switches Part Context

This part belongs to the HMC253 family of GaAs MMIC switches. Variants such as HMC253ALC4TR offer similar functionality but operate up to 3.5 GHz in a CQFN package. The HMC253AQS24 specifically targets cost-sensitive CDMA and broadband applications where non-reflective performance is critical for system stability.

RF Switches Replacement Considerations

HMC253AQS24E is a documented variant within the same package type. For higher frequency requirements, consider the HMC253ALC4TR series, which extends operation to 3.5 GHz but utilizes a different 24-CQFN footprint.
