ACPM-920502-LT1 3x4 UMTS (B5 & B2) and LTE (B5 & B2/B25) Multimode DualBand Power Amplifier Module with Integrated Coupler Preliminary Data Sheet Description 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 digitalcontrollable by the baseband chipset. The Ven pin turns...
