The WCDMA Physical Layer Demo consists of an end-to-end (transmitter-to-receiver) simulation of the Frequency Division Duplex (fdd) Downlink physical layer for several Dedicated Channels (DCH) as specified by the 3GPP standard (Release 99).

This research work aims at eliminating the off-chip RF SAW filters from fre-
quency division duplexed (fdd) receivers. In the first approach, a monolithic passive
RF filter was constructed using on-chip capacitors and bondwire inductors. The bond-
wire characteristics were studied in details and the effect of mutual inductive coupling
between the bondwires on the filter performance was analyzed. Based on that, a bond-
wire configuration was proposed to improve the frequency response of the filter. The
filter was implemented in 0.18 μm CMOS process for WCDMA applications.
