YSF-272+

Overview

The YSF-272+ is a flat gain amplifier module from Mini-Circuits, designed for high-performance RF applications. It operates within the frequency range of 2.3 GHz to 2.7 GHz, covering Wimax and UMTS bands. The device provides a nominal gain of 18 dB to 19.5 dB with superior gain flatness of ±0.7dB. It features fully matched 50 Ohm input and output impedances, integrated bias circuits, and internal feedback mechanisms. The module is powered by a 5 V supply, drawing approximately 118 mA of current. Constructed in a DL1020 plastic package with an exposed paddle and lead, it ensures unconditional stability as a balanced class-A amplifier.

Feature Summary

• Integrated input and output matching with built-in bias circuits for simplified implementation
• Superior gain flatness ensuring consistent performance across wide bandwidths
• Unconditionally stable balanced class-A architecture for reliable operation

Applications

• Wimax systems operating in the 2GHz band
• UMTS base station amplification at 2.3 GHz and 2.5 GHz
• General RF signal conditioning requiring flat gain response

Procurement Notes

Verify the specific datasheet version when sourcing, as electrical characteristics may vary slightly between revisions. Confirm that the DL1020 package footprint matches your PCB design requirements before finalizing procurement. Ensure thermal management solutions are adequate for the exposed paddle configuration to maintain junction temperatures within specified limits during continuous operation.

Selection Notes

Select this component when a drop-in solution with integrated matching and biasing is required to reduce circuit complexity. It is suitable for designs needing high gain flatness over the 2.3 to 2.7 GHz range without external tuning networks. Consider the 5V supply requirement and 118mA current draw when designing power distribution networks for the application.

Part Context

The YSF-272+ belongs to Mini-Circuits' System In Package (SiP) series, which combines active components with passive matching elements in compact packages. This approach simplifies RF front-end design by providing pre-matched stages. The DL1020 package type is common for surface-mount applications requiring robust thermal dissipation through the exposed paddle structure.
