PSA-14+

RF Amplifiers Overview

The PSA-14+ is an ultra-wideband monolithic microwave integrated circuit (MMIC) amplifier manufactured by Mini-Circuits. It operates across a frequency range of 0.01 GHz to 10 GHz with a typical flat gain of 19 dB. The device features a positive gain slope and offers high output third-order intercept point (OIP3) performance, typically +35 dBm. Designed for 50Ω systems, it provides +28 dBm output power at the 1 dB compression point. Fabricated using GaAs HBT technology, the PSA-14+ requires no external matching components, simplifying integration into broadband RF applications.

RF Amplifiers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct package type and temperature rating. Confirm that the intended application environment aligns with the component's specified operating conditions. Cross-reference part numbers with authorized distributors to avoid counterfeit products. Ensure proper handling procedures are followed due to the sensitivity of MMIC devices to electrostatic discharge during installation.

RF Amplifiers Selection Notes

Select this component when a wide bandwidth covering low frequencies up to 10 GHz is required without external matching networks. Consider the positive gain slope if system response compensation is needed. Evaluate the thermal requirements based on the specified output power levels. Compare against alternative models like ADA-4743 if direct replacement or pin-compatible substitution is necessary for existing designs.
