Hello,   I have a ST25R3916B project that is working fine, largely based around the demo_polling.c application. We use one '3916B and switch between different antennas. Each time we switch obviously the RF characteristics change a little, so I'd like...
Hello,    I have one ST25R3916B that feeds a few antennas spread out over 23 inches of length, using relays so that only one antenna is connected at a time. The ST25R3916B is located in the middle of the length. Traces are 20mil wide with ground plan...
Hello, I have several boards to design where we can fit everything into the STM32F103. We don't need USB, CAN, or Ethernet. However, the price for the '103 isn't that different from the '403 or the '722. So for a brand new project which family would ...
Hello, I'm working on a product that needs sixteen antennas, so we're looking at using the ST25R391x series but have it be single ended, with each output going to a 1:8 antenna MUX. I have the multiplexer to test but first need to get single ended ...
Hello, I have a system working that is multiplexing one ST25R3916B to sixteen antennas using relays, but we'd like to replace the relays with something quieter. Looking at either using FETs or an RF switch. However, in order to select the right solut...
