Description

The ACPM-5251 is the dual-band power amplifier module with integrated directional coupler designed for UMTS Band 1 and Band 5 uplink transmission in the mobile handsets, data cards or dongles supporting WCDMA and/ or HSPA. This product has been designed, tested and characterized to the stringent spectral linearity and other requirements of the 3GPP standards including the HSDPA, HSUPA and HSPA+ UL transmission while keeping the key emphasis on the excellent PAE over the entire power range, i.e. the exceptional average power consumption and talk-time.

Features

? UMTS Band 1 and Band 5 dual-band PA

? Integrated directional coupler (daisy-chained between both bands with single coupled out port and internally terminated isolation port)

? High directivity (small coupled power or delivered power variation into mismatched load)

? 3-mode power/gain control (active bypass, mid power, and high power modes)

? Excellent PAE in low and mid power ranges.

? 3.5mA quiescent current in active bypass (low-power) mode

? Excellent average power consumption and talk-time

? Spectral linearity supporting HSDPA, HSUPA, and HSPA+

? Internally matched 50Ω RF input & output ports

? Internal RF input & output DC blocking capacitors

? Internal Vcc bypass capacitors

? Internal Vref eliminating external LDO regulators and switches

? 1.8V CMOS compatible control logics (VH=1.35V~3.1V)

? 4 x 5 x 1mm 14-pad leadless surface-mount package

? Lead-free, RoHS compliant, Halogen-free, Sb-free, Green

Applications

? UMTS Band 1 and Band 5 Uplink Transmission in WCDMA / HSDPA / HSUPA / HSPA+ handsets, data cards and dongles
