Hello Sir/Medam,
We are working BLE based Indoor tracking project. We are selected ultra-low power wireless MCU for BLE CC2640.
We will creating two device. One is master.it will working only BLE receiver and second is slave.it will working only BLE Transmitter.
We have few queries as mentioned below.
1. We had explored BQ2640 datasheet. We saw section no 7.It describe various RF front-end configuration options. There are differential or single-ended operation. Which are suitable operation for provide best range and also low power consumption?
2. If we will select differential operation for antenna so can we use ballun chip (LFB182G45BG2D280) intend of PI filter?
3. Which types of antenna suitable for our application PCB antenna or chip type antenna?
You have better solution please suggested us for our requirement.
Regard’s
Hiren R. Thumar
