Data sheet

Annotation for characteristics section

Attenuation of WCDMA signal (“Powertransferfunction”,

WCDMA) is determined by

fCarrier according to 3GPP TS 25.101 (e.g. for UMTS-Passband, fCarrier ranges from 2112.4 MHz

(lowest Rx channel) to 2167.6 MHz (highest Rx channel)). HRRC(f) is the transfer function of the

root-raised cosine transmit pulse shaping filter according to 3GPP TS 25.101 with the following

normalization:
