My foundry provides me a CMOS model file (.hspice),
In @ds , I transform it to a .net file, but in which there
are some sentences like
#ifdef
#define
#endif
#ifdef
#define
#endif
#ifdef
#define
#endif
I don't know @ds whther support these sentences.
Please help me , thank you!
Howto install RFDE2003?
I have a copy of RFDE2003C, but I don't know howto install it?
I have installed IC5141 under RedHat 9, but RFDE2003 can't install
under RedHat 9.
PIN switch problem?
Yes, I know the reason of the problem. BA277 just works on VHF(30MHz~300MHz). Between VHF, the diode behaves very well. However, I use it in ISM(2.4GHz), so the problem happens.
PIN switch problem?
I build a switch using PIN diode(Philips BA277) , but when I measure its S12 and S21 by VNA, both of them are same. Furthermore, when added the swithcing voltage, S21 just changes 2.5 dB. I don't know what the resons are, please help me! Thanks!
I just want to reduce the current consume. the PA I have designed work on class AB status, when the input reduce the efficiency will decline and the current consume is not changed.
Now, I control the PA gain by adjusting the bias of Vbe,but this way result the input matching deteriorated. I want to know what other way is better? Thanks!
