pmb 2110 version 1.1 application specification 13 2001-07-30 3application 3.1 application circuit figure 3-1 application circuit 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. 3.2 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 pro- posal. 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. smarti: gsm: icp=0.5ma kvco=90mhz/v 15mhz/v dcs: icp=0.5ma kvco=92mhz/v 19mhz/v i ix 1k8 1k8 220p q qx 1k8 220p 1k8 100p 8.2n 180r 150r 100p vco PMB2110 pmb6250 pmb6253 cptx vtune pmb6250 pmb6253
