2.2 RF Antenna Interface
The RF interface has an impedance of 50Ω. TX62/TX82 is capable of sustaining a total mis-
match at the antenna line without any damage, even when transmitting at maximum RF power.
The external antenna must be matched properly to achieve best performance regarding radi-
ated power, modulation accuracy and harmonic suppression. Antenna matching networks are
not included on the TX62/TX82 module and should be placed in the host application if the an-
tenna does not have an impedance of 50
Ω.
Regarding the return loss TX62/TX82 provides the following values in the active band:
