Overview
WIRELESS COMMUNICATIONS DIVISION VDD TQ9203 Mixer IF out Mixer RF In Mixer LO In DATA SHEET LNA IN0 Select LNA IN1 Low-Current Cellular Band Downconverter IC LNA out GND LO Tune Features §+5-V single supply §Internal buffer amplifier on mixer LO port Product Description 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 “ antenna diversity”in applications such as CDPD.
The TQ9203 is specified over a RF frequency range of 800 to 1000MHz, and therefore may be used for any of the cellular and cordless telephony standards.
