... RTT in the multi-carrier mode. This paper describes the CDMA2000 1X RTT approach and its performance with Avago Technologies 4x4 CDMA PAs, ACPM-7813. CDMA2000 1X RTT, being an extension of the IS-95 standard, has a chip rate of 1.2288Mchip/s. However, in 1xRTT, the reverse link transmits more than one code channel to accommodate the high data rates ...

... Higher peak to average power ratio requires a higher margin, both in higher power gain and in improved thermal stability for PA linearity to meet the minimum system specifications. The test results below for the ACPM-7813 show the compliance to the system linearity specifications with 4 channel configurations, representing a broad cross-section of CDMA2000 1X RTT environments. ...
