HMC241LP3

RF Switches Overview

The HMC241LP3 is a general-purpose non-reflective Single-Pole Four-Throw (SP4T) radio frequency switch manufactured by Analog Devices Inc. It operates across a frequency range of DC to 4 GHz and utilizes Gallium Arsenide (GaAs) Monolithic Microwave Integrated Circuit technology. The device features an integrated 2:4 decoder, requiring only two control lines and a single positive bias for path selection. Key electrical specifications include an insertion loss of 0.5 dB to 0.7 dB at 2 GHz and typical off-isolation of 43 dB at 2 GHz. It supports a maximum supply voltage of 5 V with a typical operating current of 2.7 mA.

RF Switches Feature Summary

• Integrates a 2:4 TTL/CMOS compatible decoder to simplify control logic
• Provides non-reflective switching performance suitable for sensitive RF paths
• Operates on a single positive power supply for simplified biasing
• Available in leadless surface mount packages for compact design

RF Switches Applications

• Base station and repeater systems
• WLAN, WiMAX, and WiBro networks
• CATV and DBS equipment
• Portable wireless systems
• Wireless local loop applications

RF Switches Procurement Notes

Verify component status carefully as the HMC241LP3 is listed as obsolete or limited supply in major distributor catalogs. Confirm availability through authorized channels or specific factory orders. Ensure compatibility with existing PCB footprints and verify that alternative sources provide genuine Analog Devices components to maintain signal integrity and reliability standards.

RF Switches Selection Notes

Select this component for designs requiring low insertion loss and high isolation within the DC to 4 GHz spectrum. The integrated decoder reduces pin count compared to standard SP4T switches. Consider the QFN-16 package dimensions for layout constraints. Evaluate thermal dissipation requirements based on the specified power consumption and operating temperature range during system integration.

RF Switches Part Context

This part belongs to the HMC241 series of RF switches from Analog Devices. It is functionally related to variants such as the HMC241LP3E and evaluation tools like the 108333-HMC241ALP3. The series represents GaAs MMIC technology designed for cost-effective, high-performance switching solutions in wireless infrastructure and consumer electronics markets.

RF Switches Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult official Analog Devices resources for current recommended replacements or perform full parameter matching if sourcing from secondary markets.
