Universal MMIC Preamp

摘要

In 2014, a new low-noise MMIC came to my attention, the PGA-103 from Minicircuits. This device provides a sub-1dB Noise Figure up to 1296 MHz with no tuning and only costs $2. I made a number of preamps~1 on a simple PC board, like Figure 1. Then I put some of them into small Altoids tins.
