A89

Overview

The MACOM A89 is a general-purpose RF amplifier IC designed for operation within the 50MHz to 800MHz frequency range. It is housed in a TO-8B package and requires a 15V supply voltage with a typical current consumption of 130mA. Key electrical specifications include a gain of 26.5dB, a noise figure of 3.7dB, and a P1dB output power of 21.5dBm. The device supports through-hole mounting and is suitable for applications requiring broadband amplification across VHF and UHF bands.

Feature Summary

• Provides broadband amplification across VHF and UHF frequency ranges
• Designed for cascaded configurations in multi-stage amplifier systems
• Utilizes a hermetically sealed TO-8B metal package for reliability

Applications

• General purpose RF signal amplification
• Cascadable amplifier stages in communication systems
• Test and measurement equipment front ends

Procurement Notes

Verify that the specific order quantity meets the manufacturer's standard packaging requirements, as partial reels or trays may not be available. Confirm that the receiving facility can accommodate through-hole TO-8B components. Ensure that the 15V supply rail and biasing circuitry are compatible with the specified 130mA current draw before finalizing procurement plans.

Selection Notes

Select this component when a high-gain, low-noise amplifier is required for frequencies between 50MHz and 800MHz. The TO-8B package is suitable for environments where hermetic sealing is necessary. Consider the 15V supply requirement during system design, as it differs from lower voltage CMOS alternatives. Evaluate thermal management needs based on the power dissipation at full output.
