Calculate the CLC filter value for the antenna.

Postby nhatbon » Mon Jan 30, 2023 2:45 pm

I am designing RF circuit for ESP32 module.
I use an external antenna with the following parameters.
- Antenna 2.4g 6DBI / 2400-2500mhz / 50 Omh, VSWR < 1.5,
or - Antenna 2.4g 12DBI / 2400-2500mhz / 50 Omh, VSWR < 1.5, power 50W.
- ESP32 RF (30+j10) uses PI-MATCH, CLC circuit, or LCC,
What is the CLC value, what is the quality factor (Q)?, How much is the value?

How to broadcast WIFI signal far away?
Thanks everyone !

Practically, we not obtain those matching values from calculations but from tests. For test process, please see this link:https://www.espressif.com/sites/default ... nes_en.pdf
We will gradually add this part to all hardware design guidelines.

Can you give me the CLC RF value of the ESP-s2-mini-1u and esp32-wroom-32u module samples?
Because I use external antenna.
I am designing circuit for esp32 PICO chip and ESP32 S2.
I don't have an oscilloscope.
