TC35 / TC37 Hardware Interface Description

TC35_37_HD_02_V03.10 - Released Page 78 of 92 21.12.2001

The figures below show the typical peak current in dependency of load mismatch during a

transmit burst with the power control level for maximum RF power. To achieve optimum

performance the return loss of the customer application should be better than 10dB.
