Ultra fast switch

Hang in there Khad, I'm sure there are dozens of discrete semis that meet your need, probly all called some sort of electronic switch. Have you Googled yet

Is someone building an A-bomb in their back yard?

Ora, forgive an old guy and no offense, but.....

An A-bomb would need a lot more than a simple multivibrator and a Mosfet switch..

One might think so, might'n't one Tim
So let's hope Ora elucidates

What else would someone use ultra-high-speed switches for?

I don't have a background in electricity or physics, but it seems electric current doesn't travel that fast. Also, the metal used has different current speed.

Ora such a semiconductor device has hundreds if not thousands of apps. Perhaps it's that we don't understand your q

Is it possible for a semiconductor to attain such high switching speeds?

What are some of these alternative applications for ultra-high-speed switches?

A few tens of millions switching times per second (MHz) cannot even be considered ultra high speed.

Consider that we have current technology devices that switch billions of times per second (GHz).

Fast or ultra fast switches are used in uncountable types of electronic devices, from cellphones to radars..

As for the OP question, Google is full of drawings of such switches, mostly Mosfet ones.

Oh hell yes

Well gee Ora, suppose you wanted to meld two different images. Tim, Eng, if you'd name five or ten more...

I need such a switch for bidirectional amplifiers such as ...
wi fi repeaters or to build my own small communication system.....but unlike walkie talkies we should be able to send signals from both sides at a time thats why i need fast switching.....But i dont want to buy one I want to make it my self ... coz i am a learner ...


I am a graduation (B sc.) student. And we are given practicles not more then Amplifiers, Om-Amp applications etc in our college.

Again Khad, have you tried Googling where I'm sure you'll find pertinent schematics

Okay I will google it !
