QUESTION 4 The 15-54 digital cellular telephone system uses a receive frequency band of 869-894 MHz, with a first IF frequency of 87 MHz and a channel bandwidth of 30 kHz. 4.1. What are the two possible ranges for the Lo frequency? 4.2. If the upper LO frequency range is used, determine the image frequency range. Does the image frequency fall within the receive passband? 4.3. QUESTION 5 Design a colpitts oscillator operating at 200 MHz using an FET in a common gate configuration, including the effect of a lossy inductor. 5.1. Derive equations for the resonant frequency and conditions required for sustaining oscillation, for an inductor with loss. (Hint: Use with the matrix given below) (Y1 + Y2 + 9m +G) -Go + Im + Y) -(Y2 +G) (Y1 + Y2 + G.) 31 END OF ASSIGNMENT!!
