No Distribution without Written Permission Page5, Total12 1 EUT Information 1.1 Product Description CRFU is used for up-conversion and down-conversion of signals and for power amplification. The CRFU performs the following functions: • On the forward link, implementing up-conversion and power amplification for modulated transmitted signals and filtering the transmitted signals to make them meet the requirements of the air interface protocol • On the reverse link, filtering the signals received by the antenna to suppress out-band interference and then performing low noise amplification, down-conversion, and channel-selective filtering. 1.2 Technical Description of EUT Table 1. Service and Test Mode List Operating frequency band: Band Class 14: Uplink (RX): 1850 to 1915 MHz Downlink (TX): 1930 to 1995 MHz Maximum power input to the antenna: Band Class 14: a) one carrier: 42.88 dBm (for cdma2000 1X) 42.91 dBm (for cdma2000 1X EV-DO) b) two carriers:45.74 dBm (for cdma2000 1X) 45.68 dBm (for cdma2000 1X EV-DO) c) three carriers:47.41 dBm (for cdma2000 1X) 47.38 dBm (for cdma2000 1X EV-DO) b) three carriers:48.64 dBm (for cdma2000 1X) 48.79 dBm (for cdma2000 1X EV-DO) Note: The maximu…
