ACPM-5251

ACPM-5251 4x5 UMTS Band I & Band V Dual-Band Power Amplifier Module with Integrated Coupler Data Sheet 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. The ACPM-5251 contains all of the input and output matching networks, Vcc decoupling/bypass capacitors, RF input & output DC blocking capacitors as well as the daisy-chained directional coupler integrated into the module substrate PCB, all in a single 14-pad surfacemount leadless package with 4x5 mm from factor and 1mm thickness. The integrated directional coupler has a single coupledout port and is daisy-chained between the both bands with internally 50-terminated isolation port. It also has excellent coupler directivity in both bands allowing small coupled out power variation or delivered power variation caused by the load mismatch from the antenna. The coupler directivity, i.e. the power variation into the mismatched load is critical to the TRP performance of the mobile phones in the real operation as well as th...
