capacitance of the power planes on the pcb
The contradictory notes which i am talking abouts are:
One document says:
Placing a distributed Power plane between 2 ground plane layers enables an evenly distributed RF decoupling capacitance between the supply and ground. In addition, the power...
power plane emi
Hi,
Should we implement power plane in RF PCB design at 2.45GHz?
Or wide tracks sufficient for the current required will do the job.
I have read few contradictory notes regarding use of power plane in RF PCBs.
Cheers,
Hi,
What will be the effect on RF performance if i use wider track width than the actual calculated one?
For e.g. if at 2.45GHz, for 50 ohm impedance microstrip width is coming as 0.36mm for a particular PCB layer stack but i am using 0.5mm width for RF signals, what will be the impact on RF...
Hi,
I have attached one bmp file to show the system.
Probe impedance is 94.7 ohm at 2.4GHz.
In the shown image at PC board stage, we have two type of data, one with SMA connector with antenna disconnected, this represents the actual power feed to the antenna.
Another is with probe + 10:1...
85024a
Hi,
Have anybody worked with Agilent's High Frequency Probe 85024A along with 10:1 voltage divider?
I am using this assembly to measure power at 2.4GHz in a 50 ohm system in parallel with antenna of 50 ohm impedance.
kindly help me in calulating the correction factor for the signal...
electrical length transmission line
I am actually designing a RF PCB.
I have to draw a 50 ohm microstrip at 2.4GHz.
I am using RF calculator for finding out the required track width with my PCB specifications.
But I am not sure about this term "Electrical Length".
Can anyone give me some idea...
electrical length
Hi,
Can anyone help me in understanding what is the significance of Electrical Length in designing a microstrip?
When I change the electrical length parameter, it doesnot effect characteristic impedance, only the physical length got changed.
Then, what is the role of this...
