YSF-2151+

Overview

The YSF-2151+ is a surface-mount gain block amplifier manufactured by Mini-Circuits, utilizing GaAs technology. It operates within a frequency range of 900 MHz to 2.15 GHz and is fully matched to 50Ω input and output impedances. The device features built-in DC block capacitors for both input and output ports. Key electrical specifications include a typical gain of 19.8 dB, a noise figure of 2.6 dB, a P1dB compression point of 20 dBm, and an OIP3 of 35 dBm. It requires a 5 V supply voltage with a typical current consumption of 118 mA. The component is housed in an MCLP-8 package (5 x 6 mm) and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated DC blocking capacitors on input and output ports
• Fully matched 50Ω impedance for seamless circuit integration
• High linearity performance with 35 dBm OIP3
• Compact SMD packaging for automated assembly

Applications

• Cellular infrastructure base stations
• Wideband push-pull amplifiers
• LTE and 5G MIMO systems
• RFID readers and transmitters

Procurement Notes

Verify the specific datasheet revision when sourcing, as Mini-Circuits may update pinout diagrams or thermal characteristics over time. Confirm that the MCLP-8 footprint matches the PCB design, noting the 5x6mm dimensions. Ensure power supply decoupling is implemented close to the device pins to maintain stability at 5V operation. Check for RoHS compliance markings if environmental regulations apply to the final assembly.

Selection Notes

Select this component for applications requiring flat gain across the 900 MHz to 2.15 GHz band. It is suitable for designs needing high linearity (35 dBm OIP3) to minimize intermodulation distortion. Consider the 118 mA current draw for power budget calculations. The integrated DC blocks simplify biasing networks. Evaluate thermal management requirements given the plastic MCLP package and 85°C maximum operating temperature limit.
