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.

Filter connector series includes EMI/ EMP/ESD circular, ARINC, D-subminiature and micro-D connector styles. They can be combined with high energy TVS diode technology to achieve lightning and EMP transient protection. Smiths Interconnect's EMI filter connectors use multi-layer ceramic capacitor arrays together with inductive materials to realize robust, high performance low pass filter networks. Where required, transient protection can be combined with EMI /RFI filtering to provide maximum protection. The diodes as well as the EMI filter are packaged separately so the construction of the connector remains modular.

Low Voltage DC / Battery Powered High Voltage Amplifiers
WMA-005 And WMA-005LF
The Falco Systems WMA-005 is a high voltage amplifier that runs from an 24 - 30V DC power supply and can be battery powered if required, e.g. for use in a Faraday cage. Its internal high voltage generator is inductor-free and hence does not spread magnetic interference in sensitive experimental setups. The output noise is impressively low at 3mVrms. For extremely low noise applications where bandwidth is not an issue, a dedicated WMA-005LF version is available that contains an output low pass filter capacitor which reduces the bandwidth to 50Hz, but makes the noise drop to below 0.1mVrms. This bandwidth-limited amplifier is ideal for MEMS or piezo positioning with manual voltage adjustment.
