3. TECHNICAL BRIEF
3.1 General Description
The KS10 supports UMTS-2100 DS-WCDMA, EGSM-900, DCS-1800, and PCS-1900. All receivers
and the UMTS transmitter use the radio One
frequencies, directly converting signals between RF and baseband. The EGSM, DCS1800 and
PCS1900 transmitters use a baseband-to-IF up-conversion followed by an offset phase-locked loop
that translates the GMSK-modulated signal to RF.
