MMDS25254HT1 Advanced Doherty AlignmentModule (ADAM)
●The MMDS25254H is an integrated module designed for use in base station transmitters in conjunction with high power Doherty amplifiers. The device isdesigned to enable accurate alignment of phase and amplitude on the carrierand peaking amplifiers to ensure performance consistency, in particular for asymmetric implementations. TheMMDS25254H enables superior linearity--efficiency trade--off while improving output power. It contains a 90° coupler,digitally selectable phase shifters and step attenuators, and operates from asingle voltage supply. The MMDS25254H is suitable for transmit protocols suchas W--CDMA, UMTS and LTE using frequencies from 2300 to 2700 MHz, and iscontrolled using a serial peripheral interface (SPI).
