Functional Block Description
The PMB 2110 contains all circuits including resonators required for a TX VCO for a dualband (900/1800) GSM transceiver.
2.4.1
VCO core
Separate VCO cores are used for the two frequency bands. The band required can be selected with the BSW input. Both VCOs have a common frequency control input VTUNE and a common voltage supply pin VCC.
2.4.2
VCO Buffer
Separate buffers are used for both cores to amplify the VCO signals. There are two outputs for each VCO. High power single ended outputs are used to drive separate inputs for each band of the power amplifier. A separate balanced output is used to drive the downconverter of the transmit PLL. Thus the need for external circuitry to provide an input signal for this function is eliminated and the number of components required in the application is considerably reduced.

The TX Loopfilter is designed to get an optimum of RMS Phase error, 400kHz and 1800kHz suppression for GSM900/GSM1800. For more details please refer to separate application note.

Hints
DC blocking capacitors must be used at each RF output. Baseband Preemphase: The combination of IQ filtering and phase filtering due to the upconversions loops phase transfer function shows a partial cancellation of the correlated rms phase error introduced by the different blocks. This effect is utilized in the application circuit proposal. It leads to a phase error optimum for the recommended combination of loop dynamics and IQ filtering. Loop filter precharge function must be enabled together with PMB6250/PMB6253.
