Energy Saving Static Converter
-
The ENERGY SAVING static converter serves to generate a controlled squarewave single-phase alternate voltage (low frequency: 25 ÷ 125Hz) for industrial applications requiring high load power supplied by an external matching transformer. The power supply, sectioned by remote control switch and external fuses, is fed by a three-phase electric line via uncontrolled diode bridge and filtered by inductor and capacitor battery. The DC voltage thus obtained is converted into single-phase alternating voltage via “H”-shape bridge of semiconductors in order to control impressed frequency single-phase transformers.

High Voltage Op Amplifiers ≥12V
-
High supply voltage op amps are used in systems that demand the widest dynamic range with the best signal-to-noise ratio. Engineers turn to Analog Devices for high voltage amplifiers that deliver industry-leading performance. Increasingly, new high voltage amplifiers also offer features to improve system performance, cost, and robustness while easing the complexity of system design. New features include integrated input overvoltage protection (OVP), on-chip electromagnetic interference (EMI) filtering, higher electrostatic discharge (ESD) immunity, and greater resistance to latch-up in both powered and unpowered operations.

DC Filter Inductors
-
Osborne DC filter inductors (aka filter chokes) are commonly used in AC to DC conversion circuits to present an inductive voltage drop to the AC component of rectified current. This inductive voltage drop acts as a filter. Osborne designs filter inductors to components to function effectively (without saturation) in the presence of the DC current. Osborne will work with you to mitigate the impact of ripple frequency in conversion circuits. Every Osborne DC filter choke is designed for high performance with special consideration given to your circuit´s power supply frequency and conversion configuration.

Active Filter
J2190A
-
The J2190A active filter presents a high impedance (approximately 150kOhms) minimizing the loading of the circuit being tested. The output impedance is 50 Ohms allowing low noise coaxial connections to all typical test equipment. The 0.1Hz-10Hz noise band is common for opamp measurements, voltage regulators and voltage references. Many application notes offer schematics of such a filter for test purposes. An engineer’s time is much too valuable to be spent building test equipment. We have created a 4th order high pass and 4th order low pass filter with an optimally flat response and 0dB gain. Additional filters can be cascaded for even sharper cutoff.

IQ Mixers
-
The new MMIC IQ mixers from Fairview (also known as IQ modulators) utilize a highly reliable GaAs MESFET semiconductor process which integrates a pair of matched double balanced mixer cells, a 90-degree hybrid and a 0-degree splitter/combiner that produces exceptional amplitude and phase balance performance. This level of integration offers size and performance advantages in comparison to discrete module assemblies. With the addition of an external 90-degree IF hybrid module, these IQ mixers can be used as either a Single Sideband Up-converter Mixer or an Image Reject Down-converter Mixer. The benefit of image rejection and sideband suppression can reduce overall system cost and complexity by removing the need for pre-selection filtering. Typical applications include point-to-point and point-to-multipoint radio, VSAT, military radar, electronic warfare, satellite communications, test equipment, and sensors.
