UMTS Band5 (824-849MHz) 3x3mm Power Amplifier Module

Data Sheet

Description

The ACPM-5205 is a fully matched 10-pin surface mount

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.

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.

The ACPM-5205 has integrated on-chip Vref and on-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.
