HMC253QS24

RF Switches Overview

The HMC253QS24 is a non-reflective SP8T RF switch IC manufactured by Analog Devices Inc. It operates over a broadband frequency range from DC to 3.5 GHz. The device utilizes GaAs technology and features a 24-pin QSOP surface-mount package. Key electrical specifications include a maximum insertion loss of 1.4 dB and typical off-isolation of 33 dB. It supports control voltages between 2 V and 5 V, with a maximum operating supply voltage of 5 V. The unit consumes 6 mA of working current and exhibits switching times of up to 100 ns for both run and idle states. The component functions within an ambient temperature range of -40°C to +85°C.

RF Switches Feature Summary

• Broadband operation spanning DC to 3.5 GHz
• GaAs MMIC technology in a 24-pin QSOP SMT package

RF Switches Applications

• RF signal routing in wireless communication systems
• Test and measurement instrumentation
• Base station antenna switching arrays

RF Switches Procurement Notes

Verify the specific suffix 'QS24' against the required pinout and package dimensions, as Analog Devices offers multiple variants including LC4 and S24E. Confirm RoHS compliance status through official documentation. Check lifecycle status carefully, as some related models are marked obsolete or restricted. Ensure the selected variant matches the intended thermal and mechanical constraints of the target PCB design.

RF Switches Selection Notes

Select this component when a non-reflective path is critical to maintain system impedance matching across a wide bandwidth. The GaAs technology provides low noise and high isolation suitable for sensitive receiver chains. Evaluate the 24-pin QSOP footprint against available board space. Consider the 6 mA power consumption if battery life is a primary constraint in portable applications.

RF Switches Part Context

This part belongs to the HMC253 series of monolithic microwave integrated circuits designed for high-performance RF switching. The series includes various package options such as ceramic and plastic SMT types. The QS24 designation specifically refers to the 24-pin plastic quad small-outline package variant, distinguishing it from other form factors within the same functional family.

RF Switches Replacement Considerations

Public sources indicate that the HMC253QS24 model is obsolete and no longer manufactured. Review Analog Devices documentation for alternative package types or updated series components that offer equivalent SP8T functionality and frequency coverage.
