A83-1

Overview

The MACOM A83-1 is a general-purpose RF amplifier IC designed for frequencies between 10 MHz and 300 MHz. It features a gain of 35.5 dB, a noise figure of 2.5 dB, and a P1dB of -1.5 dBm. The device operates on a 15V supply with a current draw of 13 mA. It is housed in a TO-8 style package with four leads.

Feature Summary

• Discrete hybrid design utilizing thin film manufacturing processes for consistent performance and high reliability
• Two-stage architecture providing high gain within the specified frequency range
• Low voltage standing wave ratio (VSWR) across the full control range

Applications

• GPS signal processing circuits
• General purpose RF amplification
• Wideband receiver front ends

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging or environmental standards. Confirm that the TO-8 package dimensions match the target PCB footprint. Check for RoHS compliance status if restricted substances are prohibited in the final assembly. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a high-gain, low-noise amplifier is required for the 10 MHz to 300 MHz band. The TO-8 package suits applications where hermetic sealing or robust mechanical mounting is necessary. Consider the 15V supply requirement during power budget calculations. Evaluate the -1.5 dBm P1dB limit against input signal levels to prevent distortion.

Part Context

The A83-1 belongs to the A83 series of RF amplifiers manufactured by MACOM Technology Solutions. This series utilizes discrete hybrid construction techniques to achieve stable performance characteristics. The component is categorized under RF and Wireless amplifiers, specifically targeting general-purpose applications requiring reliable signal conditioning.

Replacement Considerations

The SMA83-1 is a documented related part number within the same product family. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure that any alternative component meets the same frequency range and package requirements.
