HMC321LP4TR

RF Switches Overview

The HMC321LP4TR is a broadband, non-reflective GaAs MESFET SP8T RF switch IC from Analog Devices Inc., designed for frequencies ranging from DC to 8 GHz. It features low insertion loss of 2.5 dB and typical off-isolation of 35 dB. The device operates on a maximum supply voltage of 5 V with a working current of 5 mA. Packaged in a compact QFN-24 (4x4 mm) surface-mount format, it supports positive control logic and binary switching configurations.

RF Switches Feature Summary

• Integrates eight single-pole double-throw switches into a single octal configuration
• Utilizes GaAs MESFET technology for high isolation and low insertion loss
• Features a non-reflective design suitable for signal integrity preservation
• Includes integrated on-chip binary decoding for simplified control

RF Switches Applications

• Wireless infrastructure base stations
• Test and measurement equipment
• Satellite communication systems
• Phased array antenna modules

RF Switches Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation as regional restrictions may apply. Check current lifecycle status as distribution channels may list limited availability or end-of-life conditions. Ensure the operating temperature range of -40 C to +85 C aligns with system requirements.

RF Switches Selection Notes

Select this component for applications requiring wideband coverage from DC to 8 GHz with minimal signal reflection. The integrated binary decoder reduces control line complexity compared to discrete solutions. Consider the QFN-24 package dimensions for PCB layout constraints. Evaluate power consumption against system thermal limits given the 5 mA operating current.
