MHA-054020-89

RF Amplifiers Overview

The MHA-054020-89 is a general-purpose RF amplifier integrated circuit manufactured by CML Microcircuits. It operates within a frequency range of 50MHz to 4GHz and is housed in an SOT-89 surface-mount package. The device provides a gain of 17.5dB with an output power capability of 18.5dBm. Key electrical characteristics include an input return loss of -10 dB and an isolation of -43 dB. The component has a specified power dissipation of 18.8W and is classified as moisture sensitive.

RF Amplifiers Feature Summary

• Provides linear amplification across a broad ultra-wideband spectrum from 50MHz to 4GHz
• Delivers high output power performance suitable for driving subsequent stages
• Features robust signal isolation to minimize interference between input and output ports

RF Amplifiers Applications

• Ultra-wideband signal distribution systems
• Intermediate frequency (IF) amplification stages
• Test and measurement equipment signal conditioning

RF Amplifiers Procurement Notes

Verify the specific suffix and revision level against the manufacturer's current documentation to ensure compatibility with design requirements. Confirm that the supply chain source provides authentic components, as counterfeit RF devices can exhibit significant deviations in gain and noise figures. Check for any recent product change notifications regarding pinout or thermal specifications before finalizing procurement orders.

RF Amplifiers Selection Notes

Select this component when a single-stage solution is required for wideband amplification up to 4GHz. Consider the SOT-89 package constraints for thermal management given the 18.8W power dissipation rating. Evaluate the -10 dB input return loss requirement against the source impedance of the preceding stage to ensure adequate matching without additional external components.

RF Amplifiers Part Context

This part belongs to CML Microcircuits' portfolio of RF amplifier integrated circuits designed for communication infrastructure. It serves as a gain block within mixed-signal RF systems, bridging low-level signal sources and higher-power transmission stages. The device complements other microwave MMICs and transceivers offered by the manufacturer for critical communications and network applications.

RF Amplifiers Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Verify functional equivalence by comparing the gain flatness, P1dB compression point, and operating voltage ranges. Ensure the replacement device supports the same SOT-89 footprint and thermal dissipation characteristics to maintain board layout integrity.
