Tune-Up Procedure

1 Purpose

- All the parameters (frequency band, RF channel, RF level to get the desire antenna output

power…) The user needs to make the mobile transmitting,

- All the parameters needed to define a transmit burst,

- All the compensation table to be able to align the mobile in production. This Tx_commands

user guide is describing:

- The characteristics of the transmit burst,

- All the parameters used in the transmit mode,

- The operating mode to make the mobile transmitting

2 General description

2.1 Characteristics of the transmit burst

The power levels and the shape of a transmit burst are controlled by the power amplifier

controller as shown below:

The ramping shapeis referenced with the rising of Tx-ON (from the Baseband). There are two

types of parameters define the transmit burst: the first one define the

shapes of the burst, and the second one define the temporal position of the burst. The rising and

the falling of the transmit burst are determined by a set of 32 DAC

code values n = 0 … 31.

The burst is generated by a 10-bit DAC from the SC7731E as shown below:

theSC7731E. The burst is generated by a 10-bit DAC from the

Tru = TxTRUDefault + TRU_P + TRU_T

Trd = TxTRD_NBDefault + TRD_P (for a normal burst).

TRD_P (for an access burst).

Trd = TxTRD_ABDefault +

.2 GPRS Data Transfer GSM mobile phones use a Time Division Multiple Access (TDMA) scheme to transmit data. The TDMA format contains eight time slots. The handset power amplifier typically transmits in four of these up time slots. To prevent interference between cell phones, the time mask profile as specified is very restricted.

This parameter is TRD (or TRD_P) on the panel, in the Optimal Burst. This is the compensation, which is optimized for each power control level. burst length (Note that _P means that the parameter is a power compensation parameter). 3.3.3 Tune-Up procedure of WCDMA Tx Power RPM6569-12serial PA is developed for Wide band Code Division Multiple Access (WCDMA) applications. There are different power gain corresponds to the different power mode. The power mode can be controlled by SC7731E.
