The HA-2557 is a monolithic, high speed, four quadrant,
analog multiplier constructed in Harris’ Dielectrically Isolated
High Frequency Process. The single-ended current output of
the HA-2557 has a 130MHz signal bandwidth (R_L = 50Ω).
High bandwidth and low distortion make this part an ideal
component in video systems.
The suitability for precision video applications is demon-
strated further by low multiplication error (1.5%), low
feedthrough (-50dB), and differential inputs with low bias
currents (8µA). The HA-2557 is also well suited for mixer cir-
cuits as well as AGC applications for sonar, radar, and med-
ical imaging equipment.
The current output of the HA-2557 allows it to achieve higher
bandwidths than voltage output multipliers. Full scale output
current is trimmed to 1.6mA. An internal 2500Ω feedback
resistor is also provided to accurately convert the current, if
desired, to a full scale output voltage of ±4V. The HA-2557 is
not limited to multiplication applications only; frequency dou-
bling and power detection are also possible.
For MIL-STD-883 compliant product consult the HA-2557/883
datasheet.
