   1.900-1800 Mhz

======================================

  2. CMRR measures the tendency of an Op-amp to reject the signal at input as their might be a small percentage of input signal is necessary. 


                                    

                                        CMRR = 20log₁₀  A_d/A_cm

          

                    A_{d =} differential gain

                    A_{cm =} common mode gain

======================================
