MAATSS0018TR-3000

Overview

The MAATSS0018TR-3000 is a single-channel, 1-bit GaAs MMIC digital attenuator manufactured by MACOM Technology Solutions. It provides a fixed attenuation step of 10 dB with an operating frequency range from DC to 2 GHz. The device features a 50 Ohm impedance and is housed in a compact SC-74A (SOT-753) surface-mount package. It supports control voltages compatible with standard logic levels and operates within a temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific ordering suffix TR-3000 to confirm reel packaging quantity of 3000 units. Ensure compatibility with SC-74A footprint requirements during PCB layout. Confirm that the selected variant meets RoHS3 compliance standards if required by project specifications. Cross-reference datasheet revision dates to ensure accurate electrical parameter validation before procurement.

Selection Notes

Select this component when a fixed 10 dB attenuation step is required within a DC to 2 GHz bandwidth. The SOT-753 package is suitable for high-density board layouts. Consider the 50 Ohm system impedance match for optimal signal integrity. Evaluate thermal performance limits against the specified -40°C to +85°C operational range for the intended environment.

Part Context

This part belongs to the MAATSS series of digital attenuators from MACOM. These devices are designed for applications requiring reliable RF signal control. The series utilizes advanced GaAs processing to deliver consistent performance across various frequency bands. The MAATSS0018 variant specifically targets single-bit attenuation needs in modern electronic systems.

Replacement Considerations

Check for direct substitutes within the MAATSS family offering different attenuation values or bit resolutions. Verify pinout compatibility if replacing with other SC-74A packaged attenuators. Ensure equivalent frequency response and impedance matching characteristics are maintained in alternative components.
