A78

Overview

The A78 is a general-purpose RF amplifier IC manufactured by MACOM Technology Solutions, designed for operation within the 2MHz to 350MHz frequency range. It features a gain of 14dB and a noise figure of 3.5dB. The device operates with a supply voltage of 15V and draws a supply current of 65mA. Key performance metrics include a P1dB of 19.5dBm. It is housed in a TO-8 package.

Feature Summary

• Cascadable thin-film architecture
• General-purpose RF amplification
• Wideband operational capability

Applications

• GPS signal processing
• General RF applications
• Cascaded amplifier stages

Procurement Notes

Verify the specific datasheet version (SMA78) against your design requirements. Confirm that the TO-8 package form factor aligns with your PCB layout or chassis mounting constraints. Ensure power supply stability meets the 15V requirement and thermal management supports the specified current draw during continuous operation.

Selection Notes

Select this component when a wideband, cascadable amplifier is required for frequencies up to 350MHz. Consider its low noise figure and moderate output power for signal conditioning tasks. Evaluate the through-hole TO-8 package compatibility against surface-mount alternatives if space is a constraint.

Part Context

The A78 belongs to MACOM's lineup of cascadable RF amplifiers. It utilizes thin-film technology to provide consistent performance across its operating band. This series is often utilized in systems requiring multiple amplifier stages to achieve higher overall gain while maintaining signal integrity.
