Icc Comparison of CP5 to CP4 (Avago CoolPAM)
The 5th generation of CoolPAM technology, ACPM-7382
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.
Average current & Talk time
Average current consumed by PA can be calculated by
summing up current at each output power weighted with
probability. So it is expressed with integration of multipli-
cation of current and probability at each output power.
CoolPAM
Avago Technologies’CoolPAM is stage-bypass PA technol-
ogy which saves more power compared with convention-
al PA. With this technology, the ACPM-7382 has very low
quiescent current, and efficiencies at low and medium
output power ranges are high.
Incorporation of bias circuit
The ACPM-7382 has internal bias circuit, which removes
the need for external constant voltage source (LDO). PA
on/off is controlled by Ven. This is digitally control pin.
3-mode power control with two mode control pins
The ACPM-7382 supports three power modes ( bypass
power mode/mid power mode/high power mode) with
two mode control pins (Vmode and Vbp). This control
scheme enables the ACPM-7382 to save power consump-
tion more, which accordingly gives extended talk time.
PDF (probability density function) showing distribution
of output power of mobile in real field gives motivation
for stage-bypass PA. Output power is less than 16dBm for
most of operating time (during talking), so it is important
to save power consumption at low and medium output
power ranges.

Talk time is extended more as average current consump-
tion is lowered.
Mode control pins
Vmode and Vbp are digitally controlled by baseband and
they control the operating mode of the PA. The operating
logic table is summarized on the page 2. These pins do not
require constant voltage for interface. .
