Power Amplifier Module for CDMA/AMPS T URN ON SEQUENCE 1. Connect the amplifier to 50Ω RF input and output cables. 2. Set the VCC1 and VCC2 supplies to +3.4V, and observed a current of 0mA. 3. Set the VREF supply to +2.85V. Observe a current draw of approximately 85mA from the VCC supplies. (VMODE=0V, so the amplifier is in High Bias Mode) 4. Apply an RF signal and measure the RF performance. T URN OFF SEQUENCE 1. Turn off the RF signal. Do not disconnect the PA from the RF SMAs before first turn off the DC connections. 2. Turn off the VREF and VMODE first and then turn off the VCC1 and VCC2. 3. Disconnect the PAM from the test set up.
