The TQ9203 RFIC Downconverter is a multifunction RF front end designed for the high dynamic range cellular communications standards. The design of the TQ9203 provides a 2.5dB system noise figure for excellent sensitivity, and a good signal range with 10dBm input IP3. Its low current consumption, single +5V operation and small, plastic surface-mount package are ideally suited for cost-competitive, spacelimited and portable applications. In addition, two selectable RF inputs simplify implementation of " |
