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.

Lifasa - International Capacitors, SA
The active filters offer the best possible solution to solve the problems related to the quality in the electrical network, both in industrial three-phase installations, as commercial or service installations. These problems are caused, not only by the harmonics, but also by the consumption of reactive power (generally of capacitive type).

MEMS Tunable Filter
-
Optoplex’s MEMS Tunable Optical Filter is based on a patented micro-optic design with MEMS tuning technology. It is an integrated module consisting of a MEMS chip, micro-optics and control electronics and interface. When receiving a stream of optical signals of a plurality of wavelengths from the Input-Port (IN), the 2-port tunable optical filter directs a selected channel to the Output-Port (OUT). Wavelength (frequency) tuning is achieved by changing driving voltage applied to the MEMS chip, via the control electronics and the built-in firmware.
