A70-1

Overview

The A70-1 is a cascadable RF amplifier manufactured by MACOM Technology Solutions using discrete hybrid design and thin film processes. It operates within a frequency range of 5MHz to 300MHz, with specific datasheet documentation covering 10MHz to 250MHz. Key electrical parameters include a noise figure of 1.8dB, a gain of 8dB, and a 1dB compression point (P1dB) of 14dBm. The device requires a supply voltage of 15V and draws a supply current of 15mA. It is housed in a TO-8 form factor package with four leads.

Feature Summary

• Cascadable architecture for multi-stage signal amplification
• Discrete hybrid construction utilizing thin film manufacturing for high reliability
• General purpose RF amplification capability across wideband frequencies

Applications

• GPS receiver front-end amplification
• Wireless communication systems requiring low noise performance
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the specific revision level of the datasheet, as documentation references both 10-250MHz and 5-300MHz operational ranges. Confirm that the TO-8 through-hole package aligns with the target PCB layout. Ensure the 15V supply requirement matches the system power budget before finalizing procurement specifications.

Selection Notes

Select this component when a cascadable, general-purpose RF amplifier with low noise figure is required for frequencies up to 300MHz. The TO-8 package necessitates through-hole mounting considerations. Evaluate the 15V supply requirement against available system voltages, as it differs from standard low-voltage CMOS or BiCMOS alternatives.

Part Context

The A70-1 belongs to the A70 series of RF amplifiers produced by MACOM Technology Solutions. This series utilizes discrete hybrid technology rather than monolithic integration, offering distinct advantages in linearity and power handling for specific analog applications. The component is classified under wireless and RF integrated circuits.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Designers should consult MACOM directly for qualified replacements or evaluate other cascadable hybrid amplifiers from the manufacturer's portfolio.
