Dear Team,
Can you please review the attached schematic of NRF51822 used with matching Balun and chip antenna.
Balun: 2450BM14E0003T
Chip Antenna: 2450AT18A100E (T matching network)
Please help to solve below queries:
1. Please confirm chip antenna used with a balun, will that work? Suggest matching chip antenna if I am wrong.
2. Is it ok to use R6 ( 0R ) in series with balun?
3. Pin 31 (ANT1) and Pin 32 (ANT2) are to be routed differential?
4. Please share design guidelines for Balun and Chip Antenna for good RF performance.
5. Please share the reference design for the same.
Waiting for a positive response from experts.
