HMC986A

RF Switches Overview

The HMC986A is a GaAs MMIC reflective SPDT switch from Analog Devices Inc., operating from 0.1 GHz to 50 GHz with a 50 Ohm impedance. It features low insertion loss and high isolation, suitable for radar and test equipment. The device uses a die package and supports surface mount installation. Key electrical parameters include a maximum frequency of 50 GHz and an input power handling capability typical for its class.

RF Switches Feature Summary

• Reflective single-pole double-throw (SPDT) topology
• GaAs MMIC technology for high-frequency performance
• Wideband operation covering 0.1 GHz to 50 GHz
• 50 Ohm impedance matching

RF Switches Applications

• Radar systems
• Test and measurement equipment
• Electronic warfare applications
• Microwave communication links

RF Switches Procurement Notes

Verify the specific suffix and revision level against the official Analog Devices datasheet before procurement. Confirm availability status as distribution channels may vary. Ensure ESD protection protocols are followed during handling due to the die package type. Cross-reference pin configurations with the latest documentation to avoid integration errors.

RF Switches Selection Notes

Select this component when wideband coverage up to 50 GHz is required in a reflective switch configuration. Consider the GaAs process for superior high-frequency characteristics compared to silicon alternatives. Evaluate thermal management requirements for the die package. Compare insertion loss and isolation specs against system budget constraints.

RF Switches Part Context

Part of the Hittite Microwave (now Analog Devices) portfolio of RF switches. Designed for high-performance microwave applications requiring reliable switching at millimeter-wave frequencies. Complements other SPDT and multiplexer solutions in the company's catalog.

RF Switches Replacement Considerations

Check for direct replacements such as HMC986 or updated revisions like HMC986A-SX if available. Verify that substitute parts maintain the same 50 GHz upper frequency limit and reflective topology. Ensure pin compatibility and package dimensions match existing PCB layouts.
