Conversion h-parameters from common emitter to common base (request source to verify)
Correct. My reference is Motorola RF DATA MANUAL 1978 pg. 16-136 in an app-note by Roy Hejhall "RF SMALL SIGNAL DESIGN USING TWO-PORT PARAMETERS", Appendix I. Am too lazy to do the math myself. These old paper data manuals are gold, containing much detailed reference material from BC era (before calculators).
