Product Description

The TQ9223C 3V RFIC Downconverter is a RF receiver IC front end designed for the high dynamic range cellular communications standards.

Its low current consumption, single +3V operation and small plastic surface-mount package are ideally suited for cost-competitive, space-limited and portable applications.
