PRODUCT OVERVIEW
This ultra-linear low noise amplifier module is built around the Mini-Circuits PGA-103+, delivering exceptional gain and noise figure.
The bare PGA-103+ has a known limitation: per its own datasheet, the component alone is not unconditionally stable below 100 MHz (stability factor k<1 in that range), leaving it prone to oscillation without additional circuitry.
This module solves that problem — we've added a Low Frequency Stabilization Circuit around the PGA-103+, and the finished module is unconditionally stable across its full operating range. You're getting the PGA-103+'s performance without its known low-frequency stability issue.
The module also includes ESD protection. It's well suited as a pre-amplifier for Ham Radio, TV reception, and other receiver applications — USB power means you can run it straight off a laptop. Noise figure is just 0.5 dB at 400 MHz.

Which LNA Should I Choose?
This module is the right fit if you want solid, clean gain at the lowest price point in our LNA lineup - ideal when you don't need more than 20dB, or when excess gain risks overdriving a sensitive downstream stage.
Need more gain in the same frequency range? Our 10 MHz–2000 MHz, 40 dB Gain LNA covers the same band with 20 dB more gain, at the same 0.5 dB noise figure.
Need wider bandwidth? Our 10 MHz–6000 MHz, 40 dB Gain LNA and 10 MHz–8 GHz, 40 dB Gain LNA extend coverage well beyond 2 GHz, for applications spanning a broader range of the spectrum.
