Advanced Doherty Alignment

Module (ADAM)

MMDS36254HT1

The MMDS36254H is an integrated module designed for use in base station

transmitters in conjunction with high power Doherty amplifiers. The device is

designed to enable accurate alignment of phase and amplitude on the carrier

and peaking amplifiers to ensure performance consistency, in particular for

asymmetric implementations. The MMDS36254H 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 a

single voltage supply. The MMDS36254H is suitable for transmit protocols such

as W--CDMA, UMTS and LTE using frequencies from 3400 to 3800 MHz, and is

controlled using a serial peripheral interface (SPI).
