Handsets now being developed incorporate tri-band WCDMA and quad-band EDGE platforms, an architecture that demands at least seven radios in a single handset. Most likely, the market will standardize on at least seven bands, with room for an eighth (for LTE). Regardless, complexity will continue to rise due to the increased popularity of peripheral radios and functions that also need access to the antenna.
advantages of the UltraCMOS process, the monolithic PE42693 SP9T in Figure 1 is able to maintain the +68 dBm IP3 of its SP7T predecessor with third-order intermodulation distortion (IMD3) performance that surpasses the industry speciﬁcation of -105 dBm. This level of IMD3 performance
reduces the potential for interference within the mobile handset's radio.
