3.1 General Description

The L602i supports UMTS-2100, UMTS-800 DS-WCDMA, EGSM-900, DCS-1800, and PCS-1900. All
receivers and the UMTS transmitter use the radioOne 1 Zero-IF architecture to eliminate intermediate
frequencies, directly converting signals between RF and baseband. The EGSM, DCS1800 and
PCS1900 transmitters use a baseband-to-IF upconversion followed by an offset phase-locked loop
that translates the GMSK-modulated signal to RF.
