MSA-0520

MSA-0520 Description

The MSA-0520 from Broadcom Limited is a high-performance RF amplifier designed for ISM band applications, operating across a broad frequency range of 20MHz to 2.8GHz. This surface-mount device is housed in a 200 mil BeO (Beryllium Oxide) package, offering excellent thermal conductivity and reliability. With a supply voltage range of 10.5V to 13.5V and a current draw of 80mA to 200mA, the MSA-0520 delivers a gain of 7.5dB to 9.5dB and a noise figure of 6.5dB, making it suitable for low-noise amplification in demanding RF environments. Although marked as obsolete, its performance metrics remain competitive for legacy or specialized systems.

MSA-0520 Features

• Frequency Range: 20MHz–2.8GHz, ideal for wideband ISM applications.
• High Gain & Low Noise: 7.5dB–9.5dB gain with 6.5dB noise figure for signal integrity.
• Robust Packaging: 200 mil BeO package ensures superior heat dissipation (MSL1 rated).
• Tested at 1GHz: Guaranteed performance at common RF test frequencies.
• REACH Unaffected: Compliant with environmental regulations.
• Supply Flexibility: Operates at 10.5V–13.5V, accommodating varied system designs.

MSA-0520 Applications

The MSA-0520 excels in industrial, scientific, and medical (ISM) RF systems, including:

• Wireless Communication: Signal amplification in 2.4GHz/5.8GHz ISM band transceivers.
• Test & Measurement Equipment: Low-noise front-end amplification for spectrum analyzers.
• Legacy RF Systems: Replacement or maintenance in obsolete high-frequency setups.
• RFID & IoT Devices: Enhances read range and sensitivity in UHF RFID readers.

Conclusion of MSA-0520

While the MSA-0520 is no longer in active production, its broad frequency coverage, thermal-efficient packaging, and balanced gain-noise performance make it a viable choice for legacy or niche ISM applications. Engineers seeking reliable amplification in harsh thermal environments may find this amplifier particularly advantageous due to its BeO package. For modern designs, alternative Broadcom RF amplifiers should be evaluated, but the MSA-0520 remains a testament to robust RF engineering.
