SMA74

RF Amplifiers Overview

The SMA74 is a cascadable RF amplifier from MACOM Technology Solutions, operating within a frequency range of 5 to 500 MHz. This discrete hybrid design utilizes thin film manufacturing processes for consistent performance and high reliability. The device features a two-stage bipolar transistor feedback architecture with an active DC biasing network to ensure temperature-stable operation. It offers typical gain of 30.0 dB and medium output level of +8.5 dBm. The amplifier supports a wide power supply range of +8 to +15 volts and maintains low VSWR below 1.3:1. Both TO-8 and surface mount packages are hermetically sealed, with MIL-STD-883 environmental screening available.

RF Amplifiers Procurement Notes

Verify the specific package type (TO-8 or surface mount) and ordering suffixes when sourcing. Confirm if MIL-STD-883 environmental screening is required for the application. Ensure compatibility with the specified +8 to +15 volt power supply range. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions prior to procurement.

RF Amplifiers Selection Notes

Select the SMA74 for broadband applications requiring 5 to 500 MHz coverage. Consider its 30.0 dB typical gain and +8.5 dBm output level for signal conditioning needs. Evaluate the need for hermetic sealing and military-grade screening based on operational environment. Compare against similar models like A74-1 or A76-1 if different frequency ranges or gain specifications are required.
