Advanced Doherty Alignment Module (ADAM). The MMDS20254H is an integrated module designed to enable accurate alignment of phase and amplitude on the carrier and peaking amplifiers when used in base station transmitters in conjunction with high power Doherty amplifiers and ensures Doherty power amplifier consistency, in particular for asymmetric implementations. The MMDS20254H enables superior linearity-efficiency trade-off while improving output power. It contains a 90 degree coupler, digitally selectable phase shifters and step attenuators, and operates from a single voltage supply. The MMDS20254H is suitable for transmit protocols such as GSM, W-CDMA, UMTS and LTE using frequencies from 1800 to 2200 MHz, and is controlled using a serial peripheral interface (SPI). |
