YSF-122+

Overview

The YSF-122+ is a flat gain RF amplifier module from Mini-Circuits, designed for cellular and radar applications. It operates within a frequency range of 800 MHz to 1.2 GHz. The device provides a typical gain of 20.3 dB with low noise characteristics. It requires an operating supply voltage of 5 V and draws 118 mA of current. The component is housed in an 8-DFN package measuring 4.9x6 mm. It supports surface mount technology and features integrated input/output matching and bias circuits. The operational temperature range spans from -40°C to 85°C.

Feature Summary

• Integrated input and output matching networks along with bias circuits for simplified system design
• High reverse isolation of 30 dB to minimize VSWR interactions in integrated systems
• Flat gain profile across the specified L-band frequency range

Applications

• Cellular communication systems
• Radar signal processing
• Integrated RF gain blocks

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters and mechanical dimensions. Ensure compatibility with the required operating voltage and current specifications. Check for any recent product change notices or pinout revisions before integration. Confirm that the 8-DFN package footprint matches the PCB layout requirements.

Selection Notes

Select this component when a flat gain response is required across the 800 MHz to 1.2 GHz band. Consider the 5 V supply requirement and 118 mA current draw for power budget calculations. The high reverse isolation makes it suitable for cascaded stages where stability is critical. Evaluate the thermal performance within the -40°C to 85°C range for the intended environment.

Part Context

The YSF-122+ belongs to the YSF series of flat gain amplifiers by Mini-Circuits. These modules are System In Package (SIP) components that simplify RF circuit design by integrating passive elements. The series targets applications requiring consistent gain and low noise figures over wide bandwidths, such as wireless infrastructure and sensing systems.

Replacement Considerations

Consult official Mini-Circuits documentation for verified substitute part numbers. Cross-reference specifications including frequency range, gain, and package type to ensure functional equivalence. No alternative part numbers are confirmed in the provided source material.
