KP330 Operational Description 3. TECHNICAL BRIEF 3. TECHNICAL BRIEF 3.1 General Description The KP330 supports UMTS-850, UMTS-1900, UMTS-2100, GSM-850, GSM-900, DCS-1800, and PCS-1900 based GSM/GPRS/EDGE/UMTS. All receivers and the UMTS transmitter use the radioOne Zero-IF architecture to eliminate intermediate frequencies, directly converting signals between RF and baseband. The quad-band GSM transmitters use a baseband-to-IF upconversion followed by an offset phase- locked loop that translates the GMSK-modulated or 8-PSK-modulated signal to RF.
3. TECHNICAL BRIEF KP330 Operational Description A generic, high-level functional block diagram of KP330 is shown in Figure 1.1. One antenna collects base station forward link signals and radiates handset reverse link signals. The antenna connects with receive and transmit paths through a FEM(Front End Module) (plus three duplexers for UMTS-850, UMTS-1900 and UMTS-2100 operations).
Insertion loss . this component is also in the receive and transmit paths ; In the KP330 typical losses : UMTS2100_Tx =1.2 dB, UMTS2100_Rx = 1.4 dB, UMTS1900_ Tx = 2.7 dB, UMTS1900_ Rx = 3.0dB and UMTS850_ Tx =1.9 dB, UMTS850_ Rx = 2.7 dB...
This thermistor senses temperature variations around UMTS PA to adjust PA gain deviation for assure compliance with the applicable transmit power control standards. Negative temperature compensation thermistor is used in the KP330. 3.6.5 GSM/GPRS/EDGE Power Amplifier The TQM7M5012 is a ultra-small (5x5mm), GSM/EDGE Polar PAM for handset applications.
