Low Pass and Bandpass SMA Coaxial Filters
-
Fairview Microwave’s bandpass filters were developed for use in various applications including GPS, ISM, RFID and Wi-Fi systems and operate in several bands, some as low as 824 MHz and some as high as 5.875 GHz. Fairview’s low pass filters allow for tailoring of a test setup for a specific application and support upper band edges of 100, 225, 400, 1000, 2000 and 3000 MHz. All of these bandpass filters and low pass filters feature female SMA connectors.

Mid-Range Gas Filter Correlation CO Analyzer
Model N300M
-
Teledyne Advanced Pollution Instrumentation
The Model N300M is a microprocessor-controlled analyzer used to determine the concentration of carbon monoxide (CO) in a sample gas. The analysis method is based on the Beer-Lambert law.The N300M uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapor) that also absorb IR. The analyzer passes the IR beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure.

CAT-5 Video Variable Filters
-
It is often beneficial to use a video driver at the output of a video encoder for power savings, line driving, and additional circuit protection. The video driver is typically configured as an active filter, also known as a reconstruction or anti-imaging filter. The purpose of the reconstruction filter is twofold: it blocks the higher frequency components (above the Nyquist frequency) that were introduced into the video signal as part of the digitization process and provides gain to drive the external 75 Ω cable to the video display.

LV Iron Core Harmonic Filters
-
Nonlinear loads such as power electronics based equipment and electric furnaces are sources of harmonic currents leading to harmonic distortion, which is one of the most important parameters for defining the power quality. Most of the commercial loads such as personal computers, photocopy machines, power supplies, and compact fluorescent lamps; and industrial loads such as AC and DC motor drives inject harmonic currents into the network that they are connected to.
