ACPM-5011

ACPM-5011 UMTS/LTE Band11 + Band21 (1427.9 - 1462.9 MHz) 3 x 3 mm Power Amplifier Module Data Sheet Description The ACPM-5011 is a fully matched 10-pin surface mount module developed for UMTS and LTE at Band11 and Band 21. This power amplifier module operates in the 1427.91462.9 MHz bandwidth. The ACPM-5011 meets stringent LTE (MPR = 0 dB) and HSPA+ linearity requirements up to 27.5 dBm output power. The 3 x 3 mm form factor package is self contained, incorporating 50 ohm input and output matching networks. The ACPM-5011 features 5th generation of CoolPAM circuit technology which supports 3 power modes – bypass, mid and high power modes. The CoolPAM is stage bypass technology enhancing PAE (power added efficiency) at low and medium power range. Active bypass feature is added to 5th generation to enhance PAE further at low output range. This helps to extend talk time. A directional coupler is integrated into the module and both coupling and isolation ports are available externally, supporting daisy chain. The integrated coupler has excellent coupler directivity, which minimizes the coupled output power variation or delivered power variation caused by the load mismatch from the antenna. The coupler directivity, or the output power variation into the mismatched load, is critical to the TRP and SAR performance of the mobile phones in real field operations as well as compliance tests for the system specifications. The ACPM-5011 has integrated on-chip Vref and on-module bias swit...
