A SAW-less Dual-Band CDMA Diversity and Simultaneous-GPS Zero-IF Receiver
We present a dual-band (Cellular & PCS) dual-path
zero-IF receiver for CDMA2000 diversity, monitoring and
simultaneous-GPS. The secondary path is a SAW-less diversity
CDMA receiver which can be also used for advanced features like
monitoring when supported with an additional external VCO. A GPS
receiver is integrated with its dedicated VCO allowing simultaneous
positioning during a cellular call. The circuit is implemented in a
0.25μm 40GHz-fT BiCMOS process and uses a HVQFN 56-pin
package. It consumes a maximum 300mW from a 2.8V supply in
dual-modes. The chip area is 12.8mm2.
