ACPM-5204

ACPM-5204 UMTS Band4 (1710-1755MHz) 3x3mm Power Amplifier Module Data Sheet Description The ACPM-5204 is a fully matched 10-pin surface mount module developed for UMTS Band4. This power amplifier module operates in the 1710-1755MHz bandwidth. The ACPM-5204 meets stringent UMTS linearity requirements up to 27.8dBm output power. The 3mmx3mm form factor package is self contained, incorporating 50ohm input and output matching networks. The PA also contains internal DC blocking capacitors for RF input and output ports. The ACPM-5204 features 5th generation of CoolPAM (CoolPAM5) circuit technology which supports 3 power modes – active bypass, mid power and high power modes. The CoolPAM is stage bypass technology enhancing PAE (power added efficiency) at low and medium power range. The active bypass feature is added to CoolPAM5 to enhance the PAE further at low output range and it enables the PA to have exceptionally low quiescent current. It dramatically saves the average power consumption and accordingly extends the talk time of mobiles and prolongs a battery life. 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 T...
