How can i pulse a DC current at a rate of Ghz

AI Thread Summary
To pulse a DC current at 2.45 GHz, an astable multivibrator circuit can be utilized, which generates square waves. Key considerations include the acceptable rise and fall times of the pulses, as well as the desired on-time to off-time ratio. The discussion highlights the importance of component selection to achieve the required frequency and pulse characteristics. Additionally, the thread references previous discussions on related issues, indicating ongoing interest in high-frequency DC pulsing techniques. Achieving reliable performance at GHz frequencies requires careful design and testing.

how can i "pulse" a DC current at a rate of Ghz

i need to pulse a dc current through a circuit in at 2.45Ghz. astable multivibrator style
How might i go about doing this

Why?
What are the maximum rise and fall times you can accept?
What on-time to off-time ratio do you need?

Thread 'Weird near-field phenomenon I get in my EM simulation'

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
