UMTS Dual-Band 4x5mm Power Amplifier Module (Band2/Band5)

Avago Technologies 

Mode control pins

Vmode and Vbp are digitally controlled by baseband and they control the operating mode of the PA. The logic table is

summarized in the below table. These pins do not require constant voltage for interface.

The 5th generation of CoolPAM technology, ACPM-7355

can dramatically reduce Icc down to 3mA at bypass mode,

which improves overall talk time and battery usage time

of handset more compared with the CP4.
