Quality factor in antenna matching / question about SX1261 LoRa transceiver
I have a question about how the quality factor is determined for RF antenna matching, especially for PI network matching.
The reason for the question is the Reference Design for antenna matching for the SX1261 LoRa transceiver:
C9 = C10 = 3.3pF, L5…

SemTech SX126x antenna matching
SemTech SX126x, LLCC68. Please, I could not find the component values for a matching antenna at 433 MHz and +22dbm. Do you have a schematic and list of nominal values for this? I was only able to find an evaluation kit with the 868MHz setting.

SX1261/2 transceiver design: Antenna pins and balun
I am designing my first transceiver (first PCB/IC that uses an antenna). I chose SX1261/2 because it is cheap and supports LoRa protocol. While designing the PCB and reading the datasheet of the IC I have some questions. I did make a previous…

What is the logic design behind multiple pins for antenna output/ input on tranceivers
I am making my first transceiver using SX1261/2 and I am trying to understand the pinout of the antenna (input and output) pins.
At page 101 I see a typical schematic and I want to know more about why more than 1 pins are used for the output antenna…
