This is a quick eval board for the pSemi PE4259, a SPDT RF switch. The official eval board is nearly one hundred bucks. That’s a bit much for my tinkering projects, so I decided to build my own version.
R1 and R2 are 1k ohm, R3 is 10k ohm. Square pads are pin 1. PWR-1 is 3.3V, PWR-2 is GND. CTRL-1 is connected to 3.3V, and is connected to RF-6 via R1. CTRL-2 is connected to RF-4 (CTRL) via R2, while R3 provides a pull-down on that same pin.
Traces should be ~50 ohms when using OSHParks 0.8 mm/2oz process.
No guarantees are made, use at your own risk, etc…
