Key Features

Ultra Low Noise MMIC Amplifier

PSA-5454+

50

Ω

0.05 to 4 GHz

CASE STYLE: CA1389

Product Overview

Mini-Circuits PSA-5454+ is a E-PHEMT based Ultra-Low Noise MMIC Amplifier operating from 50 MHz to

4 GHz with a unique combination of low noise and high IP3 making this amplifier ideal for sensitive receiver

applications. This design operates on a single 5V supply at only 20mA and is internally matched to 50

ohms.

Feature

Advantages

Ultra Low Noise, 0.8 dB

Outstanding Noise Figure, measured in a 50 Ohm environment without any external matching

High IP3, 25 dBm

Combining Low Noise and High IP3 makes this MMIC amplifier ideal for Low Noise

Receiver Front End (RFE) because it gives the user advantages at both ends of the dynamic

range: sensitivity & two-tone spur-free dynamic range

Low Current, 20 mA

At only 20mA, the PSA-5454+ is ideal for remote applications with limited available power or

densely packed applications where thermal management is critical.

Broad Band

Operating over a broadband the PSA-5454+ covers the primary wireless communications bands:

Cellular, PCS, LTE, WiMAX

Internally Matched

No external matching elements required to achieve the advertised noise and output power over the

full band

SOT-363 Package

Small size, industry standard package

Max Input Power, +15dBm

Ruggedized design operates up to input powers of +15dBm without the need of an external limiter

High Reliability

Low, small signal operating current of 30 mA nominal maintains junction temperatures typically

below 105°C at 85°C ground lead temperature

The Big Deal

• Ultra Low Noise Figure, 0.8 dB

• High IP3/Low Current, 20mA at +5V

• Wideband, up to 4 GHz
