pls help
hi,
I am using Microwave Office to design a PA @900MHz. However, as seen in the circuit, there is no gain at all. I am new to this and want to ask if anyone can let me know what's wrong with my circuit.
And there's one more doubt: when I fabricate the circuit, I need to add certain microstrip in between the SMD. However, is there any rules in adding these microstrips and what effects they have?
I got the s-parameters result and they match to my measurement but with up to 5dB degradation.
Can anyone give me some advice?
