HMC550ATR

RF Switches Overview

The HMC550ATR is a GaAs MMIC SPST RF switch from Analog Devices Inc., operating from DC to 6 GHz. It features a reflective topology with 0.7 dB insertion loss and 12 dB isolation. The device supports 3.3 V or 5 V supply voltages, delivering an IIP3 of 52 dBm and P1dB of 32 dBm. Packaged in a compact SOT-23-6 surface-mount housing, it is designed for WiMAX and WLAN applications within a -40°C to 85°C temperature range.

RF Switches Feature Summary

• Utilizes GaAs MMIC technology for high-performance signal switching
• Provides fail-safe operation with low power consumption
• Offers compact SOT-23-6 packaging for space-constrained designs

RF Switches Applications

• WiMAX base station and subscriber unit front ends
• WLAN infrastructure and client devices
• RF signal routing in communication systems

RF Switches Procurement Notes

Verify the specific suffix against official documentation, as distributor listings may contain conflicting frequency ranges (e.g., 2.5 GHz vs 6 GHz) or voltage specifications. Confirm current availability status, as some sources indicate limited supply or obsolescence for related variants. Ensure the component matches the required electrical parameters for your specific circuit design before ordering.

RF Switches Selection Notes

Select this component for applications requiring a single-pole single-throw switch with high linearity and low insertion loss up to 6 GHz. Consider the reflective topology when designing impedance matching networks. Verify that the control voltage levels are compatible with the available 3.3 V or 5 V supply options provided by the datasheet.

RF Switches Part Context

The HMC550 series includes variants such as the HMC550A and HMC550AE. The HMC550A is listed as obsolete with the HMC550AE as a parameter-equivalent replacement. The HMC550ATR represents the tape-and-reel packaging version of this GaAs MMIC switch, maintaining the same core electrical characteristics as the leaded counterparts.

RF Switches Replacement Considerations

The HMC550AE is documented as a parameter-equivalent replacement for the HMC550A. Verify pinout compatibility and electrical performance equivalence with official manufacturer data before substituting.
