class AB power amplifer output power Response time

[coolsaurabhsonu]

hiiiii all,

i am working on Class AB power amplifer, problem is that the Output Power at load settles constant after long time, how to improve that response time.

It's impossible for anyone to even start diagnosing the problem unless you provide ALL details about your design - schematic, testing method, frequencies involved, what you consider to be a "long" settling time, etc.

hiiii

i m working on CLASS B Push pull power amplifier frequency Range 402-405MHz , i have to design a power amplifier that can deliver 500uwatt power to 50 ohm load.
the thing want to know is

1. when i m doing transient analysis and calculating power at 50 ohm load ,the power at load is settling after 25n sec . but i want to improve this settling time. how to do improve that one??

2.when i m doing Transient analysis i m getting 500u watt power at 50 ohm load, but when i m doing PSS analysis then power drops down to half (250uwatt) of the transient simulation result ,please tell me why this is so..
