MMDS09254H|700-1000 MHz

For best experience this site requires Javascript to be enabled. To enable on your browser, follow our accessibility instructions.

The MMDS09254H 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 MMDS09254H 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 MMDS09254H 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).
