I have 2 questions and any help is appreciated.
The frequency is at 5.5 to 6 GHz range. RF trace impedance is 50 ohms.
- I have a resistive splitter to split RF signal into 2 traces with 6 dB attenuation. What is the correct way of placing the Zo/3 ohm resistors on the PCB? I placed R31, R32, and R33 as below with T like orientation. Would it be any better if I move R31 and R32 to sides and put R33's pad right between them? What is the most correct way of placing these 3 resistors?
- I want to add u.fl connectors at some stages of RF signal path next to RF trace for debugging purposes. I learned that 0 ohm resistor or 10-100 pF capacitor can be used. Is there any difference between splitting with 45 degree or 90 degree angle? Right connector's trace is split using 0 ohm jumper resistor with 90 degrees angle to PCB antenna's RF trace. Is that ok or could it be better if the angle between traces have an angle like mitered bend? Because when I solder 0 ohm to select u.fl connector then the RF signal will see a 90 degree corner which is not recommended.
