this is s11 and s22 smith charts and rectangular plots.
yes some missmatch not much miss mach :)
and there is no refrence circuit in datasheet.and i do not use any biasing circuit for this simulation as you see.and also because of i do not have x-parameters i can not use nonlinear...
I found a power transistor that is broadband internally matched FET from Toshiba company. I found it’s S-parameter file(s2p file block) from Toshiba company’s internet site.
I simulate it with S-parameter simulation of ADS with two SP-Probe for impedance watching of it like this:
And the...
you must see some examples on microwave transistor amplifiers design and analysis,Gonzalez
but first you must check your transistor is stable or not then matching
thank you but i want to use this for a power amplifier, i want to know my source in reality equalls to which source and i must use which in ADS?(i want to use computer power source for biasing the transistors, and assume to use this amp for radar applications)
in addition to this when i used a...
you must just name a line in input and aline in output(like "in" and " out")search in this site for how to name a line
then in result page click on in then "add vs" then click on out and you can see the result you want
i have a problem with input power in ads,harmonic balance.
in harmonic balance simulation i put 3 element:
1-v1_tone(sin wave AC signal) in input
2-a s2p file block for a broadband internally matched transistor(FET)
3-a 50 ohm term(port) in output
i want to have a constant average power in...
pay attention:: I talk about a new way to this. not wilkinson or ...
I found 2 papers that show new dividers with new shapes.
1- Design technique and performance assessment of new multiport multihole power divider suitable for M(H)MIC's
2- Multiport Power Divider-Combiner Circuits Using...
yes i know it,but because of high temperature and burning possibility i want to use none resistors.
please help me in a way that need no transistor and handle high power and equal divide.
thanks.:?:
i want to design an equal 4-way power divider without resistor that can handle high power up to 40w and small size for an amplifier.
i find some papers,but i want to all output ports be equal.
do you suggest anything that can satisfy my conditions?:grin:
please help me with details for...
is it possible that i import s2p file block and an ideal amplifier with s12=1 & s21=1 and import P1dB and Psat and ... in ideal amplifier?
and what characters of transistor from data sheet should be import in ideal amplifier that are placed serie with s2p file block?
i have a transistor with datasheet and s2p file and i want to simulate an amplifier design with this transistor.
i imported this with a 2-port file block that need s2p file. but other characterizations like P1dB?????
please help me on it.
