Multiplication circuit in broadband video band used

Posted on Mar 28, 2007

Although the respective inputs are differential inputs, but the right amplifier is greater than the general OP bias current (800nA), so as the input coupling capacitor, confide

nce should be noted that the resistance value (on the input side should also be applied to the X2, balancing resistor, etc.) use it as a balanced modulator circuit assassination elbow, Yin from the input carrier modulated signal is equal to zero when adjusting variable resistor v roar to achieve equilibrium carriers (carrier leak happened). VRi power supply circuit using bad if the power supply stability, it will undermine the transition load balancing © Since bandwidth ioMHz/- 3d B. Used in the phase shift of power when the road should be noted.
