Figure 11: Test Configuration

Figure 12: Test Configuration

V+ = 3V

pin 7 is forced to idle mode after that the two compressor have been

forced at maximum gain by V11 and V17

Input signal on pin 4 VATTE = 200mVpp

Rpin24 = 11KΩ

ATE6 = 20log(VOUTE / VATTE)

V+ = 3V

pin 11 is forced to 100mV to force the transmit mode

VTIM_E voltage on pin 7

ITIM_E current through the mA
