Mini-Circuits PSA-5451+ 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 3V supply at only 30mA and is internally matched to 50
ohms.
Key Features
Feature
Ultra Low Noise, 0.7 dB
Advantages
Outstanding Noise Figure, measured in a 50 Ohm environment without any external matching
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
At only 30mA, the PSA-5451+ is ideal for remote applications with limited available power or
densely packed applications where thermal management is critical.
Operating over a broadband the PSA-5451+ covers the primary wireless communications bands:
Cellular, PCS, LTE, WiMAX
No external matching elements required to achieve the advertised noise and output power over the
full band
Small size, industry standard package
Ruggedized design operates up to input powers of +15dBm without the need of an external limiter
Low, small signal operating current of 30 mA nominal maintains junction temperatures typically
below 100°C at 85°C ground lead temperature
High IP3, 29 dBm
Low Current, 30mA
Broad Band
Internally Matched
SOT-363 Package
Max Input Power, +15dBm
High Reliability
