Hello Community experts,
I am working on my company's new product line designing about 10 products. We are planning to use S2-LP transceiver for 868MHz and 915 MHz devices. For at least 2 products, we need as long range as possible. Since the Half Wavelength dipole antenna has the highest radiation efficiency, we are evaluating this type on PCB antenna.
As we all know, dipole antenna is a balanced (differential) antenna. It can be interfaced with a transceiver with differential input/output. However, the S2-LP has balanced receiver (RXp and RXn pins), but unbalanced output (Tx). We want to use the matching BALUN (BALF-SPI2) made by ST, as this also has built-in harmonic filter.
Question: How can I interface S2-LP with a 868-915 MHz dipole antenna?
This is the 1st time we are planning to use S2-LP, so I am new to it. I hope someone will give me an answer.
Thanks.
AB Singh
