I originally starting working on this device about the same time as the Sky65116 power amplifier. The idea was that I should put a PA on the transmitter, and a low-noise amplifier (LNA) on the receiver. In this post, I’ll discuss the why and how of LNAs, as well as the construction and evaluation of the Sky65047 400MHz to 3GHz LNA board shown below. I’ve had these boards sitting on the bench for quite some time, and I finally got all the random-value passives that I needed gathered and the equipment necessary to measure it.
