Application for APT
Application Information
The use of DC / DC converter can enhance the efficiency of the ACPM-50xx PAs and this note presents an example of
their APT applications in a 3 G / 4 G system.
1. The Vcc1 pin of PAs is directly connected to a battery or the phone power: 3.2 V to 4.2 V
2. The Vcc2 pin of PAs can be adjusted to its lowest value according to Tx average power level over discrete intervals that

still meets the linearity requirements (e.g., ACLR1 -39 dBc @ Rel’99): 0.5 V to 3.4 V
• DC-DC converter generates the voltage for the Vcc2 port and it is controlled by the PDM signal from BB chipsets.
• Bypass Capacitors (22 pF and 0.1 µF) should be placed as close to the module as possible (the Vcc1 Pin and the
• Bypass Capacitors (0.1 µF and 4.7 µF) should be shared by other band PAs to minimize noises and have best RF
Vcc2 Pin, respectively).
