Antenna matching for PICO-D4

Postby Vader_Mester » Wed Jan 31, 2018 2:09 pm

HI All,

I want to use a PICO-D4, with a 50ohm chip antenna (this one)

I noticed, that in the PICO-D4 datasheet, there is some matching circuitry included, and it says the input is 50ohms.

Do I need any additional external components for matching this antenna, or the ones integrated into the PICO is well enough.
And if so, what components and configuration do you recommend?

Thanks
Vader [BEN]

Code: Select all

task_t coffeeTask()
{
	while(atWork){
		if(!xStreamBufferIsEmpty(mug)){
			coffeeDrink(mug);
		} else {
			xTaskCreate(sBrew, "brew", 9000, &mug, 1, NULL);
			xSemaphoreTake(sCoffeeRdy, portMAX_DELAY);
		}
	}
	vTaskDelete(NULL);
}

			xSemaphoreTake(sCoffeeRdy, portMAX_DELAY);
		}
	}
	vTaskDelete(NULL);
