Epcos has developed what it claims is the smallest duplexer for the WCDMA Band VIII. The duplexer is based on a SAW-SAW combination and measures in at only 3,0 x 2,5 x 1,1 mm. The product features very high isolation values with simultaneously low insertion losses of 1,7 dB in the Tx path and 2,0 dB in the Rx path. Thus, the amplifier stages before and after the duplexer can be designed to minimise power consumption in line with these low attenuation values, which in turn extends the standby times of the end-product. A balun is additionally integrated in the Rx path for impedance matching and balancing from 50 to 100 Ω, making the duplexer compatible with all common chipsets.
Band VIII of the UMTS standard is now being introduced in Europe to augment Band I. The special advantage of Band VIII is based on its use of the relatively low bandwidths of 880 to 915 MHz in the Tx path and 925 to 960 MHz in the Rx path. UMTS phones and base stations equipped for Band VIII have ranges comparable with those of GSM systems, meaning that no additional base stations need to be built to achieve required coverage.
