[HMC8205BF10] 10 ns-width pulse input and output?

Hello. 

I want to get output Voltage larger than 100 V peak to peak.

So I have some questions in the data sheet from figure 25.

< Output Power (POUT), Gain vs input power at 1 GHz >

for example, when 

Input: 24 dBm / Gain: 21 dB / output: 45 dBm    

 mean 

Input: (~3.5 Vrms) = (~10 Vpp)   /  output: (~40 Vrms) = (~110 Vpp)   right?? 

Then what would outcome be when I input 10 V-10 ns widh pulse to "HMC8205BF10" ?

How can I calculate the out voltage?  

and the pulse width of outcome would be similar to input? 

Regards,

SeeWoo Lee

    Hi SeeWoo,

                         The lowest operating frequency the HMC8205BF10 will operate at is 300 MHz. So, no it won't be able to handle a dc pulse.

    Your first condition: 380 MHz 10V p-p should be fine . that translates to 27 dBm re: 50 ohms for a square wave and leaves you some margin. The absolute  max input rating is 35 dBm or 25V p-p for a pulse re 50 ohms.

    I've attached a link to a calculator which will help you convert between voltage levels and power. The waveform can be changed as well as the characteristic impedance. the HMC8205B is a 50 ohm characteristic impedance.
