HMC349AMS8GETR

RF Switches Overview

The HMC349AMS8GETR is a GaAs SPDT RF switch IC from Analog Devices, operating from DC to 4 GHz. It features an insertion loss of 1.2 dB at 3 GHz and typical isolation of 50 dB. The device operates on a single 5 V supply with a current draw of 1.2 mA. It is housed in an 8-lead MSOP package with an exposed pad and supports SMD/SMT mounting. The unit weight is 20.4 mg, and it functions within a temperature range of -40°C to +85°C.

RF Switches Feature Summary

• High isolation performance for effective signal path separation
• Nonreflective design ensures stable signal transmission
• CMOS compatible control logic simplifies interface integration

RF Switches Applications

• Wireless communication systems requiring signal routing
• Test and measurement equipment needing precise switching
• RF front-end modules in mobile devices

RF Switches Procurement Notes

Verify the specific suffix GETR against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles before procurement. Cross-reference the part number with authorized distributors to confirm active status and avoid obsolete inventory.

RF Switches Selection Notes

Select this component when high isolation and low reflection are critical for system integrity. The CMOS-compatible control interface reduces complexity in digital control schemes. Evaluate the thermal dissipation requirements relative to the exposed pad design for reliable operation in compact PCB layouts.

RF Switches Part Context

This part belongs to the HMC349A series of high-isolation switches. It utilizes Gallium Arsenide (GaAs) technology for superior RF performance. The series is designed for applications demanding nonreflective switching characteristics across wide bandwidths.

RF Switches Replacement Considerations

HMC349ALP4CETR offers similar functionality but differs in package type (QFN-16 vs MSOP-8) and isolation specifications.
