PSA-8A+

RF Amplifiers Overview

The PSA-8A+ is a monolithic microwave integrated circuit (MMIC) amplifier manufactured by Mini-Circuits. It operates from DC to 4000 MHz with a typical gain of 31 dB and a noise figure of 4.8 dB at 100 MHz. The device provides a 1 dB compression point (P1dB) of 12.8 dBm and draws 36 mA from a 5 V supply (4.75V ~ 5.25V). Packaged in an SC-70-6 surface-mount case, it is designed for cellular and PCS applications.

RF Amplifiers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct package and tape-and-reel specifications. Confirm RoHS compliance status and lead-free certification requirements prior to procurement. Cross-reference the part number with authorized distributors to avoid counterfeit components. Ensure voltage supply ranges match system design constraints.

RF Amplifiers Selection Notes

Select this component for designs requiring high gain and low noise in compact surface-mount layouts. The SC-70-6 package suits space-constrained PCBs. Verify thermal management capabilities as the device dissipates power during operation. Ensure input/output impedance matching aligns with 50-ohm system requirements across the DC to 4 GHz bandwidth.

RF Amplifiers Part Context

This MMIC amplifier belongs to Mini-Circuits' portfolio of RF amplifiers designed for wireless communications. It utilizes heterojunction bipolar transistor (HBT) technology to achieve stable performance across temperature variations. The device integrates biasing and matching networks internally, simplifying circuit design for cellular and PCS frequency bands.

RF Amplifiers Replacement Considerations

Consult Mini-Circuits documentation for direct replacements or pin-compatible alternatives within the same family. Verify electrical parameter equivalence for gain, noise figure, and supply current when substituting. Ensure mechanical footprint compatibility if replacing on existing PCBs.
