Procurement Notes

Verify the specific datasheet version and technical specifications directly with MACOM Technology Solutions or authorized distributors before procurement. Confirm that the TO-8 package configuration and thin film construction meet the exact requirements of the target application environment. Ensure compliance with all relevant environmental and trade regulations associated with the component supply chain.

Selection Notes

Select this component when a cascadable RF amplifier with a 1 MHz to 300 MHz operational range is required. The 4.2 dB noise figure and 21.0 dB gain are suitable for intermediate frequency stages where moderate noise performance is acceptable. Consider the discrete hybrid construction for applications prioritizing reliability over miniaturization compared to monolithic integrated solutions.

Part Context

The A75-2 belongs to the MACOM portfolio of radio, microwave, and millimeter wave semiconductor devices. As a discrete hybrid amplifier, it differs from monolithic integrated circuits by using thin film processes to achieve precise electrical characteristics. This design approach supports high-reliability applications in wireless and RF integrated circuit subsystems.

Replacement Considerations

The SMA75-2 is documented as a related variant within the same product family. Verify pinout compatibility and specific electrical tolerances when substituting between these models to ensure functional equivalence in the existing circuit design.
