Notes
1) _{The RF input B is symmetrical driven by means of a hybrid for 180° phase shifting, consequently the source}
W W impedance is 100 . All other impedance for RF tests is 50 .
2) _{The noise figure (NF) is the value for double-side-band measurement.}
3) _{The intermodulation test (2-carrier-method) which is made on IF-centre}
is in reference to a signal-to-IM ratio of 60 dB.
4_{) Gain is the ratio of the voltage at the primary coil of L5 to the available voltage at the input.}
