3x4 UMTS (B5 & B2) and LTE (B5 & B2/B25) Multimode Dual-
Band Power Amplifier Module
with Integrated Coupler
Preliminary Data Sheet
The ACPM-920502 is the multimode dual-band power amplifier
module with integrated directional couplers designed for UMTS
(3GPP B2 & B5) and LTE (B5 & B2/B25) handsets as well as the
wireless data card applications. It is designed to meet the stringent
linearity requirements of WCDMA, HSDPA, HSUPA, HSPA+ UL
and LTE transmission while keeping excellent PAE over the entire
power range by supporting 2 power modes (low and high power
modes). This PA has low quiescent current and high PAE in both
power modes. So the average power consumption is minimized to
enhance the talk time.
The ACPM-920502 contains integrated directional couplers, 50Ω
input and output matching networks, RF input & output DC blocking
capacitors as well as the Vcc decoupling/bypass capacitors,. All
these functions are integrated in a 16-pin surface-mount leadless
package of 3x4 mm form factor and 0.9 mm thickness, so it can
minimize the number of external components.
The integrated LB & HB directional couplers are daisy-chained
internally. One coupler input port and one coupler output port are
shared by the both bands.
The ACPM-920502 has integrated on-chip Vref and on-module
bias switch, so the external LDO regulators and switches for
external Vref are not required. It also makes the PA fully digital-
controllable by the baseband chipset. The Ven pin turns the PA on
and off by the digital control signal. All of the digital control input
pins such as the Ven and Vmode are fully CMOS compatible down
to the 1.8V logic.
