S-Parameter Files: ------------------ Within this directory you are able to see the main operating point information within the filename: For bipolar transistors you have to read as follows: the filename XXAAABBB.S2P is coded: XX internal type definition AAA shows the voltage; V means Volt; the character stands instead of the decimal point ie. 10V means 10Volts; 1V0 means 1.0Volts BBB shows the current; M means mA, A means Ampere, U means ľA; the character stands instead of the decimal point ie. 10M means 10mA; 1M0 stands for 1.0mA; A10 for 0.1A; 10U for 10ľA; (this is also valid for the GaAs FETs) For diodes you have to read as follows: the filename XXAAABBB.S1P is coded: XX internal type definition AAA shows the voltage; V means Volt; the character stands instead of the decimal point ie. 10V means 10Volts; 1V0 means 1.0Volts BBB shows the current; M means mA, A means Ampere; U means ľA the character stands instead of the decimal point ie. 10M means 10mA; 1M0 stands for 1.0mA; A10 for 0.1A; 10U for 10ľA; if the voltage is V00 the diode is foreward biased and a current is shown if the current is U00 the shown voltage is the backward biasing voltage For files , changed v( volt) into p, are measured in forward direction forward direction is marked with negativ VR For MOS FETs and dual gate GaAs-FETs you have to read as follows: the filename XXAABBCC.S2P is coded: XX internal type definition AA is UDS in V*0.1 i.e 50 means 5.0V; 15 means 1.5V; BB is UG(2)S in V*0.1 ie 35 means 3.5V; 10 means 1.0V; CC is ID in mA ie 10 means 10mA; 05 means 5mA; README.TXT V4.0 September 2000
