hi all!
why there is no nonlinear model for rd01mus mosfet? how i can simulate class c drive amplifier VHF using rd01mus without nonlinear model in ADS like image in attachment?
thank you in advance!
hi all
i finally simulate VHF class a amplifier using ADS and the transistor is BFG97.
i used its model from NXP and imported it in ADS as netlist file.
in simulation i got gain result almost same as S2P file @ VCE=10V,IC=70mA, i got about 36 dB gain with input and output
impedance matching. i...
thank you so much vfone
there is no problem for designing impedance matching.
my only problem is how to make class a circuit amplifier simulation in ADS for getting (30.3 dB) gain @ 100 MHz and (24.4 dB) @ 300MHz like result from s2p for bfg97 bjt ??
thank you in advance!
thank you so much vfone
i appreciate your effort for replying.
for Q4 why it dosn't has dc-block capacitor?
why we can't named c22 as dc-block capacitor for coupling two stages amplifier?
is there source explain how to design class a rf amplifier with impedance matching?
thank you in advance!
thank you for replying.
it is practical schematic for ICOM v80 transceiver from it's service manual. not simulation circuit but i want to know if they simulate circuit like this, have they got close result in comparison to practical result?
if we talk about first stage, is it class a amplifier...
hi all
please any body can tell me how they simulate this (ICOM v80) 3 stages amplifier? and what is the suitable model they used??
thank you in advance!!!
yes in picture it looks 40 MHz but i'm tried at 100MHz and 200MHz it's also not consistent.
i just wanted to make class a amplifier with real model, i know should maybe put RFC inductor with collector but i didn't tried with it.
really i'm confused if i must put terms 50 ohm in front of source...
Mr BigBoss i just made this circuit practically and simulation.
in simulation with real model for bfg97 (PACKAGE : SOT223A DIE MODEL : BFR96) i got vout=145mV @ vin=10mV but in real circuit i got only vout=75mV @ vin=10mV.
what do you think for that please!
thank you so much
thank you sooo much.i succeeded finally, every thing is ok but please i want your opinion about the comparison of (simulation and S2P) S parameters result please!
@ VCE=10V,IC=30mA, f=200MHz.
thank you so much Mr BigBoss.
i imported spice model netlist for BFG97 transistor but i don't know how i can link and connect with (simulation amplifier circuit) from design guide and netlist spice model for bfg97. is there example or video please!
i'm sorry but i'm beginner in ads...
