Hot-selling and scarce ACPM-5001-TR1 Multimode PA - UMTS Band1 and CDMA IMT 3x3mm Power Amplifier Module with Coupler QFN

Product Descriptions

The ACPM-5001-TR1 is a fully matched 10-pin surface  mount module developed to support multimode applications including UMTS Band1 and CDMA IMT band(Band6).  The ACPM-5001-TR1 meets stringent linearity requirements up to 28.25dBm output power for UMTS Rel.99  and 27.75 dBm for CDMA. 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-5001-TR1 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 TRP and SAR performance of the mobile phones in real field operations as  well as compliance tests for the system specifications.

The ACPM-5001 has integrated on-chip Vref and on-module  bias switch as the one of the key features of the CoolPAM-5,  so an external constant voltage source is not required,  eliminating the external LDO regulators and switches  from circuit boards of mobile devices. It also makes the PA  fully digital-controllable by the Ven pin that simply turns  the PA on and off from the digital control logic input from baseband chipsets. All of the digital control input pins  such as the Ven, Vmode and Vbp are fully CMOS compatible and can operate down to the 1.35V logic. The current  consumption by digital control pins is negligible.

The power amplifier is manufactured on an advanced  InGaP HBT (hetero-junction Bipolar Transistor) MMIC  (microwave monolithic integrated circuit) technology  offering state-of-the-art reliability, temperature stability  and ruggedness.
