Balanced_high_level_mixer
This circuit shows the SL6440 (Fig. 2-10) with a balanced input (for improved carrier leak), and balanced output (for increased conversion gain). A lower VCC can be used with this arrangement (for lower device dissipation).Conversion gain for the balanced circuit of Fig. 2-11 is equal to: Gdb 20=20 Log56.61 IP+0.0785,2RLIP.where IP is programmed current at pin 11, and RL is dc load resistance.
