ACPM-920502-LT1 Datasheet | Avago Technologies

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 ponents. 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 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 patible down to the 1.8V logic. Features - Multimode dual-band PA supporting UMTS B5 & B2 and LTE (B5 & B2/B25) - 2-mode power/gain control (low power and high power modes) - Integrated daisy-chained LB & HB directional couplers - High directivity (small coupled power or delivered power variation into mismatched load) - Excellent PAE in low and mid power ranges. - Low quiescent current in low power mode - Excellent average power consumption and talk-time - Spectral linearity supporting HSDPA, HSUPA, HSPA+, and LTE...
