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 FCG: Uplink (RX): 1890 to 1915 MHz Downlink (TX): 1970 to 1995 MHz Maximum power input to the antenna: Band Class 14 FCG:: a) one carrier: 43.41dBm (for cdma2000 1X) 43.11dBm (for cdma2000 1X EV-DO) b) two carriers:46.31 dBm (for cdma2000 1X) 46.19 dBm (for cdma2000 1X EV-DO) c) three carriers:47.98 dBm (for cdma2000 1X) 47.69 dBm (for cdma2000 1X EV-DO) b) three carriers:49.24 dBm (for cdma2000 1X) 49.00 dBm (for cdma2000 1X EV-DO) …
