NXP MMDS09254HT1

高级 Doherty 校准模块700MHz ~ 1GHz

Overview

The MMDS09254HT1 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 MMDS09254HT1 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 MMDS09254HT1 is suitable for transmit protocols such as GSM, W-CDMA, UMTS and LTE using frequencies from 700 to 1000 MHz, and is controlled using a serial peripheral interface (SPI).
