RF-to-IF Front-end Receiver

N/A is an RF-to-IF (radio frequency to intermediate frequency) front-end receiver designed for cellular, personal communications service (PCS) and Global Positioning System (GPS) signal processing. It integrates GPS capability with a CDMA front-end receiver. It has a silicon germanium (SiGe) BiMOS radio frequency integrated circuit (RFIC) that provides high linearity with very low power consumption. The advanced integration of a GPS receiver into a CDMA/AMPS receiver eliminates the need to add an extra stand-alone GPS RF receiver.

The gpsOne solution exceeds the Federal Communications Commission's (FCC) specifications for E-911 Phase II capabilities. It also offers robust data availability under challenging conditions, such as in concrete-and-steel high-rises, convention centers, shopping malls or urban canyons.

N/A device integrates dual-band low noise amplifiers (LNAs) and mixers for downconverting from RF to CDMA and FM IF, and contains a dedicated LNA and mixer designed for downconverting global positioning system (GPS) signals from RF to IF. N/A receiver operates in the 832 MHz-894 MHz cellular band, 1840 MHz-1990 MHz PCS band and 1575 MHz GPS band. N/A device meets cascaded Noise Figure (NF) and Third-Order Input Intercept Point (IIP3) requirements of IS-98 and JSTD-018 for sensitivity, and two-tone intermodulation. N/A solution was also designed to meet the sensitivity requirements of gpsOne.
The cellular LNA in N/A device offers gain control capability for improving dynamic range and performance in the presence of high levels of interference. Reducing the gain in the LNA also improves power consumption. Band selection and gain modes are controlled directly from the MSM3300 chip. N/A device is designed for use with voltage ranges from 2.7 V to 3.15 V, and is available in a 5 millimeter by 5 millimeter 32-pin BCC++ plastic package.
