A87-2

Overview

The A87-2 is a cascadable RF amplifier manufactured by MACOM Technology Solutions. It utilizes a discrete hybrid design with thin film manufacturing processes to ensure accurate performance and high reliability. The device operates within a frequency range of 5 MHz to 350 MHz, covering the 10-300 MHz band specified in some documentation. Key electrical characteristics include a noise figure of 3.0 dB and a gain of 16.0 dB. The component is constructed using Silicon (Si) technology and is available in a TO-8 package.

Feature Summary

• Discrete hybrid design utilizing thin film manufacturing for high reliability
• Cascadable architecture suitable for multi-stage signal amplification
• Silicon-based construction ensuring accurate RF performance

Applications

• General purpose RF amplification
• Wireless communication systems
• RF integrated circuit interfaces

Procurement Notes

Verify the specific datasheet version and ordering suffixes when sourcing, as availability may vary. Confirm that the TO-8 package matches your board layout requirements. Ensure the operating frequency range aligns with your system's 5 MHz to 350 MHz specifications. Check for any recent product change notifications that might affect pinout or performance parameters before finalizing procurement plans.

Selection Notes

Select the A87-2 when a cascadable, high-reliability silicon RF amplifier is required for frequencies up to 350 MHz. Its discrete hybrid design offers precise performance compared to monolithic alternatives. Consider the TO-8 package form factor for compatibility with existing test fixtures or mounting solutions. Evaluate the 16.0 dB gain and 3.0 dB noise figure against system link budget requirements to ensure adequate signal integrity.

Part Context

The A87-2 belongs to MACOM’s portfolio of wireless and RF integrated circuits, specifically categorized under RF amplifiers. It is part of a family that includes similar models like the A87-1, which covers a slightly different frequency range. These components are designed to support high-speed connectivity and analog interface needs in modern electronic systems.

Replacement Considerations

The A87-1 is a related model from the same manufacturer but operates in the 10-400 MHz range with a 3.4 dB noise figure. Verify if the extended upper frequency limit and slight noise figure difference are acceptable for your application before substituting.
