HMC546MS8GETR

RF Switches Overview

The HMC546MS8GETR is a GaAs MMIC SPDT RF switch designed for high-power applications. It operates from 200 MHz to 2.7 GHz with a typical insertion loss of 0.4 dB and off-isolation of 24 dB. The device supports up to 20 Watts of power handling and features a failsafe configuration. It functions within a supply voltage range of 3 V to 8 V, dissipating 1.12 W of power. The component is rated for operation between -40°C and +85°C and is available in an MS-8 package.

RF Switches Feature Summary

• High power handling capability of 20 Watts for robust signal routing
• Failsafe design ensures defined output state upon control signal loss
• Low insertion loss of 0.4 dB maintains signal integrity across the band
• GaAs MMIC technology provides reliable performance in harsh environments

RF Switches Applications

• Base station transmit/receive switching
• Test and measurement equipment signal routing
• Military and aerospace communication systems

RF Switches Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the frequency range requirement matches the 2.7 GHz maximum specification rather than the lower 2.2 GHz variant often cited in older documentation. Ensure the 20W power rating aligns with system thermal management capabilities. Check for moisture sensitivity level requirements during storage and reflow processes. Validate that the MS-8 package footprint fits the target PCB layout constraints.

RF Switches Selection Notes

Select this component when high linear power handling is critical alongside low loss. Compare against the HMC546LP2ETR if a smaller DFN-6 package is required, noting its lower 10W power rating. Consider the HMC546MS8GE if leaded packaging is preferred over surface mount. Evaluate thermal dissipation needs given the 1.12W power consumption. Ensure the control voltage levels are compatible with the 3V to 8V operating range.

RF Switches Part Context

This part belongs to the HMC546 series of high-power GaAs switches from Analog Devices. The series includes variants like the LP2E and MS8G packages. These components are engineered for demanding RF environments requiring high linearity and power handling. The MS8GETR variant specifically denotes the surface-mount tape and reel configuration for automated assembly.

RF Switches Replacement Considerations

• HMC546LP2ETR (Lower power, different package)
• HMC546MS8GE (Leaded version)

RF Switches FAQ

What is the failsafe behavior of the HMC546MS8GETR?

The switch is designed to default to a specific output port when the control voltage is removed or falls below the threshold, ensuring predictable signal paths.

Does the 2.7 GHz maximum frequency apply to all specifications?

Yes, the datasheet specifies the operational frequency range extends up to 2.7 GHz, although some marketing materials may cite 2.2 GHz as a standard test point.
