PHA-23LN+

RF Amplifiers Overview

The PHA-23LN+ is a surface-mount MMIC low noise amplifier from Mini-Circuits, designed for CATV and cellular applications. It operates over a frequency range of 30 MHz to 2 GHz with a nominal gain of 21 dB. The device features a 50 Ohm impedance interface and utilizes an SOT-89 package. Key electrical characteristics include a typical noise figure of 2.6 dB and a third-order input intercept point (IIP3) of +34 dBm. It supports operation within a temperature range of -40°C to +85°C.

RF Amplifiers Feature Summary

• Provides high linearity performance with excellent dynamic range across the operating bandwidth
• Delivers stable gain flatness suitable for broadband RF signal processing
• Integrates medium power linear pHEMT technology for reliable amplification

RF Amplifiers Applications

• CATV distribution systems
• Cellular base station front ends
• Satellite communications receivers

RF Amplifiers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required pin configurations or thermal specifications. Confirm that the SOT-89 package variant matches the intended PCB footprint and thermal management requirements for the target assembly process.

RF Amplifiers Selection Notes

Select this component when a balance of low noise figure and high linearity is required for frequencies up to 2 GHz. Consider the SOT-89 package constraints regarding thermal dissipation and board space. Evaluate if the 21 dB gain meets system link budget requirements without excessive downstream amplification.

RF Amplifiers Part Context

This part belongs to the PHA series of low noise amplifiers from Mini-Circuits. It shares functional similarities with other models in the family but is distinguished by its specific gain profile and SOT-89 surface mount packaging. It serves as a dedicated solution for mid-band RF amplification tasks.

RF Amplifiers Replacement Considerations

The LHA-23LN+ is a documented alternative offering similar frequency coverage but utilizes a QFN package instead of SOT-89. Verify layout compatibility before substitution.
