Gain Shaper
. The output of the integrator is fed to the gain
shaping circuit that drives the gain control input of the external
RF PA. The midpoint voltage of the PA control voltage VPC, is
determined by the VMP input. The VMP input is obtained by
connecting a resistor divider to the 2.4 V reference output,
VREF. The integrator in the integrating error amplifier is used to
stabilize the loop.
The maximum voltage obtainable on VPCGSM and VPCDCS is
generally 1 V below VCC2 (pin 20). Therefore, it may be more
desirable to use a higher voltage than VCC.
Output Stages
. Each of the two output stages is dedicated to a
frequency band: one for GSM900MHz and one for
GSM1800/PCS1900 MHz. The selection of the output stage is
determined by the BAND select signal. A high signal selects the
VPCDCS as the output pin and a low signal selects VPCGSM
as the output pin. When either output is inactive, its residual
output level is extremely low to ensure that the inactive PA is
completely off.
DC Bias Block. The DC bias block provides voltage bias to the
whole chip, which may be put in standby mode using the
ENABLE digital input control pin (pin 6). The ENABLE pin is
compatible with TTL levels. When the ENABLE pin is driven
high, the device is enabled.
Electro-Static Discharge (ESD) Sensitivity
The RF142 is a static sensitive electronic device. Do not operate
or store it near strong electrostatic fields. Take proper ESD
precautions.
