CoolPAM
Avago Technologies’ CoolPAM is stage-bypass PA tech-
nology which saves more power compared with conven-
tional PA. With this technology, the ACPM-7372 has very
low quiescent current, and efficiencies at low and medium
output power ranges are high.
Incorporation of bias circuit
The ACPM-7372 has internal bias circuit, which removes
the need for external constant voltage source (DO). PA
on/off is controlled by en. This is digitally control pin.

The ACPM-7372 supports three power modes (bypass
power mode/mid power mode/high power mode) with
two mode control pins (mode and bp). This control
scheme enables the ACPM-7372 to save power consump-
tion more, which accordingly gives extended talk time.
PD (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.
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.
Average current =
(PD x Current)dp

Icc Comparison of CP5 to CP4 (Avago CoolPAM)
The 5th generation of CoolPAM technology, ACPM-7372
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.
