PROJECT

A First Look at the Si5351 Clock Generator

I’m considering using the Si5351 as the quadrature oscillator in my receiver. I’ve read a lot about this part, but I’m still unsure how it will perform in practice, so I bought a breakout board to experiment with. In order to make experimentation easy, I’m using a set-up that allows me to configure the part using Python code running on my […]

PROJECT

Mixer Sub-Circuit Prototype

Having convinced myself that the Si5351 can directly drive a pair of ADE-1 mixers, I decided to prototype the mixer stage of the receiver. The main goal was to confirm that the mixing action is working with this set-up, and to make some measurements of the outputs. Here’s the circuit diagram: And here’s what the build looks […]
