描述 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.

特性 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
