The TSFP-4 package has two emitter leads. To avoid high
complexity fo the package equivalent circuit, both leads are
combined in one electrical connection.
RLXI are series resistors for the inductances LXI and Kxa-by are the
coupling coefficients between the inductances Lax and Lyb. The
referencepin for the couple ports are B, E, C, B`, E`, C
