2、MT6158 Function Block

MT6158Transceiver RF Overview

Single mode C2K 

transceiver

– Multi-band C2K

– 1xRTT Rev0, 1xEV-DO Rev0/A

HW Feature

– TX SAWless, RX SAWless

– RX diversity and SHDR supported

– TX: 2HB+1LB, 

RX: 2HB+1LB, 

RXD/SHDR: 2HB+1LB

– On-chip DCXO

MT6158 Support RX diversity and SHDR

(a) Single antenna hybrid mode.

(b) Dual antenna legacy hybrid mode but there is only one Rx PLL so those two Rx chains have to be switched together.

(c) SHDR hybrid mode since there are two PLLs in Rx chains
