YSF-322+

Overview

The YSF-322+ is a low noise linear amplifier from Mini-Circuits, operating within the 900 MHz to 3.2 GHz frequency range. It utilizes GaAs technology and is housed in an MCLP-8 (8-DFN) SMD package measuring 4.9x6 mm. The device provides a typical gain of 16 dB with a noise figure of 2.5 dB. Key performance metrics include a P1dB compression point of 20 dBm and an OIP3 of 35 dBm. It requires a 5 V supply voltage and draws 118 mA of current. The unit maintains a flat gain response of ± 2.2 dB across its bandwidth and features integrated input/output matching for direct 50 Ω interfacing.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and electrical characteristics. Confirm that the received component matches the MCLP-8 package dimensions and RoHS compliance status. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity. Ensure storage conditions adhere to moisture sensitivity levels specified in the handling guidelines. Check for any recent design changes or obsolescence notices before finalizing procurement orders.

Selection Notes

Select this component when a wideband low noise amplifier is required between 900 MHz and 3.2 GHz. It is suitable for applications demanding high linearity, indicated by the 35 dBm OIP3 rating. The integrated matching network simplifies PCB layout compared to discrete solutions. Consider the 118 mA current draw for power budget calculations. This amplifier is ideal for systems requiring minimal external passive components while maintaining stable 50 Ω impedance matching.
