Description
RF input to the DCS band. This is a 50
Allows external control to select the GSM or DCS band with a logic high
or low. A logic low enables the GSM band whereas a logic high enables
the DCS band.
This signal enables the PA module for operation with a logic high. Once
TX Enable is asserted the RF output level will increase to -2dBm.
Power supply for the module. This should be connected to the battery.
Regulated voltage input for power control function. (2.8V nom)
Ramping signal from DAC. A simple RC filter may need to be con-
nected between the DAC output and the VRAMP input depending on
the baseband selected.
