cdma 2000 1xRTT Characterization
System Description
CDMA2000 is the TIA’s standard for third generation
(3G) technology and is an evolution of the IS-95 CDMA
format. CDMA2000 includes 1X RTT in the single-carrier
mode and 3X 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.

The minimum configuration consists of a reverse pilot
(R-Pilot) channel for synchronous detection by the Base
Transceiver System (BTS) and a reverse fundamental
channel (R-FCH) for voice. Additional channels such as
the reverse supplemental channels (R-SCHs) and the
reverse dedicated channel (R-DCCH) are used to send
data or signaling information. Channels can exist at
different rates and power levels.
Table 1 shows the transmitter specification in
CDMA2000 reverse link.
Table 1. Transmitter Specification in Reverse Link.
Typical channel configurations below are based on the transmitter test
condition in the reverse link.
1) “Basic” Voice only configuration
– R-PICH @ -5.3 dB
– R-FCH @ -1.5 dB 9.6 kbps
2) Voice and Data configuration
– R-PICH @ -5.3 dB
– R-FCH @ -4.54 dB 9.6 kbps
– R-SCH1 @ -4.54 dB 9.6 kbps
3) Voice and Control configuration
– R-PICH @ -5.3 dB
– R-FCH @ -3.85 dB 9.6 kbps
– R-DCCH @ -3.85 dB 9.6 kbps
4) Control channel only configuration
– R-PICH @ -5.3 dB
– R-DCCH @ -1.5 dB 9.6 kbps
