Notes
1)
W W ^{The RF inputs B and C are symmetrical driven by means of a hybrid for 180° phase shifting, consequently the}
source 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.}
