About the MAX2870/2871 Dev Board
MAX2870/2871 Dev Board is an open source PCB design by joshajohnson, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 48 × 48 mm, with 46 components from 23 distinct parts.
Other key parts include the AMS1117-3.3, LP5907MFX-3.3, MAX2871 and MIC5366-1.8. By type, the board carries 29 capacitors, 8 resistors, 4 ICs, 2 connectors and 2 inductors.
It belongs with the dev boards & breakouts designs in this gallery.
From the project
25MHz to 1.25GHz Vector Network Analyser
Design is feature complete, but not suitable for use. Due to hardware issues the error is unacceptably large, and as such I can not recommend assembling one of these.
