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.

Mid-Range Gas Filter Correlation Carbon Monoxide Analyzer
Model T300M
-
The Model T300M CO analyzer measures low to mid ranges of carbon monoxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO filled chamber and a chamber with no CO present. The light path then travels through the sample cell, which has a folded path of 2.56 meters.The energy loss through the sample cell is compared with the span reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance from low to high range.All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T300M comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.

Anechoic Chamber Filters
-
RF leakage through Ethernet and USB cables can destroy even the best RF enclosures and chambers. The need for filtering in the ever congested RF environment requires special filters that can pass USB 2.0 and 10/100/1000 Mbps Ethernet signals and filter out unwanted higher frequencies such as cellular and WiFi. The Adaura Technologies USB/Gigabit Filters provide one GigE and one USB 2.0 pass-through connections while filtering out other RF up to 8GHz. It has a small form factor to allow easy installation. It is a most cost effective solution for a clean chamber set up. In a typical chamber, WiFi signals are reduced to <-100dBm with this filter installed.

Narrow Band Filters (Single Octave)
NANO-POLE® Series
-
The NANO-POLE® is designed for optimal size, DC consumption, RF power handling, insertion loss, signal purity and linearity. The NANO-POLE® provides a minimum center frequency step size of 10 MHz typically but can be modified based upon request. The NANO-POLE® requires a +3.0 V supply that typically draws 5 mA when not hopping. The supply voltage should be adequately filtered as noise present on this pin will influence the RF signal purity. The NANO-POLE® uses SPI control interface.

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.
