 TA0016 End RFIC RF2403: European Applications for RF2403 Cordless Telephone Front       
         A front end RFIC for cordless telephone applications has been developed for use in the 902MHz to 928MHz ISM (Industrial-Scientific-Medical) band in the United States under Part 15 of the FCC Rules. .

Features

. With both enable lines at logic low, the circuit is in a “power down” mode in which it draws approximately 1.0mA of leakage current from the VDD supply. Some external passive components are required, primarily for DC blocking and RF bypassing functions. The PA output impedance matching circuitry, consisting of a pinetwork, is realized using external passive components in order to both conserve die area and to reduce parasitic losses. This same RFIC has been evaluated for use in 433MHz European applications, and has been found to have very good RF performance there. Although no changes have b.
