Is gain bandwidth product measured in dB or voltage gain?

[aspsrilanka]

If anyone know pls tell me in Gain bandwidth product, gain in what manner (dB or voltage gain (Vo/Vi)) ?

 

[vk6kro]

It is in voltage gain (Vo/Vi) * bandwidth in MHz.

thanks lot

Sorry for being intrude, but it is worth while to know that the dB values never should be multiplied or divided. The only allowable operation on dB quantities are addition and subtraction.
Also since the GBWP units is Hz, so the Gain should be unitless (Volt/Volt).
