RF Switches Procurement Notes

Verify the specific suffix 'ETR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status and manufacturing origin through official Analog Devices documentation. Ensure the order matches the exact part number to avoid confusion with non-tape variants or alternative series members.

RF Switches Selection Notes

Select this component for designs requiring cost-effective SPDT switching up to 3 GHz. Consider the SOT-23-6 footprint for space-constrained PCB layouts. Evaluate thermal management requirements against the specified power dissipation limits and operating temperature range for reliable performance.

RF Switches Part Context

This part belongs to the HMC545 family of low-cost SPDT switches. The 'AE' variant denotes a specific grade or revision, while 'ETR' specifies the reel packaging format. These devices are designed for integration into wireless communication modules where compact size and moderate isolation are sufficient.
