I am designing circuit with the help of Quicksmith as it free. Hence i downloaded .s2p file accrdingly.
This is what i got in.s2p file.
! FILENAME: NE73432C.S2P VERSION: 5.0
! NEC PART NUMBER: NE73432E DATE: 01/83
! BIAS CONDITIONS: VCE = 10V, IC = 20mA
# GHZ S MA R 50 S11 S21 S12 S22
0.100 0.440 -101.00 19.270 122.00 0.030 65.00 0.660 -26.00
For noise figure :
TYPICAL NOISE PARAMETERS (TA = 25°C) VCE = 10 V, IC = 20 mA
FREQ. NFOPT GA ΓOPT
(MHz) (dB) (dB) MAG ANG Rn/50
500 1.40 19.5 0.26 122 0.17
Now i want to feed input to quicksmith from the above with Chart parameter impedance will be 75 ohm.
There r three inputs in the quicksmith.
1. S parameters
2. Noise parameters
3. Chart parameters. : i will put here 75 ohms.
Now just tell me what s parameter & noise parameter input i hv to put for S11, S21, S12 & S22 & noise parameters from the above?
