7 / 26 page RX IF/BBA WITH AGC S1M8656A 7 AC CHARACTERISTICS Characteristic Test Conditions Symbol Min Typ Max Unit CDMA Performance Input sensitivity Maximum AGC gain. Control input signal so that output corresponding to 3LSB is output from ADC. The current source impedance is 500 Ω and matched by connecting a 1kΩ resistance to the differential input. VCSEN -102 - - dBm Maximum input signal Minimum AGC gain. Control input signal so that output corresponding to 3LSB is output from ADC. The current source impedance is 500 Ω and matched by connecting a 1kΩ resistance to the differential input. VCMAX - - -12 dBm AGC gain slope PDM is controlled to 3.3V and finds the differential gain between the control voltage of 1V and 2V. GSLOPE 33 45 53 dB/V AGC gain error over temperature The difference in gain slope between when the temperature is -30 °C and +85°C. GVAR -3 - 3 dB IF input frequency range The IF frequency is increased to find the frequency where the gain falls below -3dB. Fin 250 - - Mhz Input power = -102dBm NFmin - 7 - dB Noise figure Input power = -75dBm NFmid - 20 - dB Input power = -25dBm NFmax - 70 - dB IIP3 AGC gain Max. IIP3max -55 - - dBm AGC gain Min. IIP3min -10 - - dBm Spurious contents ADC generated harmonic frequency component. Two signals in the in-band are each mixed with signals which will allow ADC to produce -7dB output signals. The harmonic and non-harmonic components of the ADC output signals between 1kHz – 20MHz are extracted and added. The AGC control voltage is controlled so that ADC output is full scale when the input signal is -80dBm. TSpur - - -25 dBc Spurious content related to jammer In-band spurious peak value produced by IMD based on 2 jammer signals. One in-band signal(@50kHz,0.5*F/S) and two jammers(@900kHz, 22dB*F/S and @1.7MHz, 21dB*F/S)are simultaneously input. AGC control voltage is controlled so that ADC output is F/S when the input signal is -80dBm. Jspur - - -18.4 dBc |
