ACPM-5205
UMTS Band5 (824-849MHz) 3x3mm Power Amplifier Module
Data Sheet
Description
Features
The ACPM-5205 is a fully matched 10-pin surface mount ꢀ Thin Package (1.0mm typ)
module developed for UMTS Band5. This power amplifier
module operates in the 824-849MHz bandwidth. The
ACPM-5205 meets stringent UMTS linearity requirements
up to 27.5dBm output power. The 3mmx3mm form factor
package is self contained, incorporating 50ohm input and
output matching networks. The PA also contains internal
DC blocking capacitors for RF input and output ports.
ꢀ Excellent Linearity
ꢀ 3-mode power control with Vbp and Vmode
– Bypass / Mid Power Mode / High Power Mode
ꢀ High Efficiency at max output power
ꢀ 10-pin surface mounting package
ꢀ Internal 50ohm matching networks for both RF input
The ACPM-5205 features 5th generation of CoolPAM
(CoolPAM5) circuit technology which supports 3 power
modes – active bypass, mid power and high power modes.
The CoolPAM is stage bypass technology enhancing
PAE (power added efficiency) at low and medium power
range. The active bypass feature is added to CoolPAM5 to
enhance the PAE further at low output range and it enables
the PA to have exceptionally low quiescent current. It
dramatically saves the average power consumption and
accordingly extends the talk time of mobiles and prolongs
a battery life.

A directional coupler is integrated into the module and
both coupling and isolation ports are available exter-
nally, supporting daisy chain. The integrated coupler
has excellent coupler directivity, which minimizes the
coupled output power variation or delivered power
variation caused by the load mismatch from the antenna.
The coupler directivity, or the output power variation into
the mismatched load, is critical to the TRP and SAR per-
formance of the mobile phones in real field operations as
well as compliance tests for the system specifications.

Description (Cont.)
The power amplifier is manufactured on an advanced
InGaP HBT (hetero-junction Bipolar Transistor) MMIC
(microwave monolithic integrated circuit) technology
offering state-of-the-art reliability, temperature stability
and ruggedness.
TheACPM-5205hasintegratedon-chipVrefandon-module
bias switch as the one of the key features of the CoolPAM-5,
so an external constant voltage source is not required,
eliminating the external LDO regulators and switches
from circuit boards of mobile devices. It also makes the PA
fully digital-controllable by the Ven pin that simply turns
the PA on and off from the digital control logic input from
baseband chipsets. All of the digital control input pins
such as the Ven, Vmode and Vbp are fully CMOS compat-
ible and can operate down to the 1.35V logic. The current
consumption by digital control pins is negligible.
