Wideband Multifunction Reception System GaAs MMIC Completely Covers GPS and CDMA CXG1100TN CXG1115ER The gpsOne system is seen as a revolutionary technology for the next generation of position information services. The gpsOne system uses information from GPS satellites and the CDMA network to complement each other and acquire reliable positioning information. (See figure 1.) A position information service that uses gpsOne cellular phones is scheduled to start service this fall in Japan. Sony has now developed a chip set that responds to the needs of this market. The CXG1100TN is a wideband DPDT switch, and the CXG1115ER is a dual-mode front-end IC. These devices adopt Sony’s unique JFET process and mounting technologies to achieve high functionality and miniaturization. CXG1100TN s s s s s s s Switching can be controlled from CMOS lines Wide bandwidth, low insertion loss, and low distortion Provided in an ultraminiature package CXG1115ER Dual band support Circuit area reduced by the adoption of 2× frequency multiplier technology High gain, low noise, low distortion Provided in an ultraminiature package CXG1100TN DPDT Switch Switching Can Be Controlled from CMOS Lines The CXG1100TN is a DPDT*1 antenna switch MMIC. While conventional single band systems use a SPDT* 2 switch, the CXG1100TN supports dualband systems with DPDT operation. In this device, Sony integrated logic circuits on the same chip by using Sony’s unique GaAs JFET E/D hybrid process. This device can be direc...
