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.

Ground EMI Filters
-
High-frequency signals on ground is never good news - it interferes with normal operation of equipment and creates electrical overstress (EOS). However it is easy to block propagation of EMI on ground by installing highly-effective ground EMI filtes in ground lines. Our unique patent-pending ground EMI filters provide very low impedance for DC and mains' power while effectively blocking propagation of high-frequency currents throughout facility or equipment ground. Ground filters meet safety standards, as well as ANSI/ESD S6.1 and ANSI/ESD S20.20.

CTS develops and manufactures high-end radio frequency (RF) filters used by various technologies to block out or filter certain signal frequencies. In 1982, CTS invented the ceramic monoblock, and ever since, our ceramic RF filters have been setting the industry standard in terms of lowest insertion loss, attenuation /rejection/isolation, Q-factor, size, power handling, and transition slope. Our portfolio includes band-pass filters, notch filters, low-pass filters, delay line filters, diplexers, duplexers, and triplexers/multiplexers.

Band Pass Filters
-
VDI offers up-converter modules for communication applications. The double sideband nature of the up-converter modules makes filtering necessary. VDI has designed filters to filter one sideband and preserve signal modulation. These filters offer low passband insertion loss and high out-of-band rejection. Custom filters may be available upon request. NRE (non-recurring engineering) fee may be required.
