... Data Sheet Current Mode Four Quadrant Multiplier The EL4083 makes use of an Elantec fully complimentary oxide isolated bipolar process to produce a patent pending current in, current out four quadrant multiplier. Input and output signal summing and direct interface to other current mode devices can be accomplished by simple connection to reduce component count and preserve bandwidth ...

... Input Voltage NOTES: 1. Specifications are provisional for the EL4083. 2. Error is defined as the maximum deviation from the ideal transfer function expressed as a percentage of the full scale output. 3. Linearity is defined as the error remaining after compensating for scale factor (gain) variation and input and output referred offset errors. ...

... Current Outputs (I Distortion Another unique feature of the EL4083 is the differential ground referenced current output structure. These outputs can drive 50: terminated lines and reactive loads such as transformers, baluns, and LC tank and filter circuits directly (See EL2082 Data Sheet_Receiver IF Amplifier (Figure 19) ...

... Applications Basic Product Functions Figures 18 and 19 are the basic schematics for many of the applications of the EL4083. These can perform signal mixing, frequency doubling, modulation, demodulation, gain control/voltage-controlled amplification, multiplication and squaring. Figure 18 has resistively terminated differential outputs and has the widest bandwidth. The figure also shows the option of using the EL2260 dual CMF amplifier to recover the outputs differentially at very low impedance ...
