High Performance Lowpass Filters

LPS Series of High-performance Low Pass filters with quick availability

Allen Avionics designs and manufacturers Lowpass filters using mainly Chebyshev and Elliptical algorithms. Our LPS Series are high performance filters designed to pass the fundamental frequency with less than 1.0 dB attenuation and attenuate all harmonics over 95 dB.  They are designed using the specifications and techniques that work for most precision signal conditioning high performance testing applications. In a typical application they are used to enhance the performance of all test generators and signal sources used in testing A to D, D to A converters, amplifiers and other electronic components. They improve selectivity and dynamic range of all spectrum analyzers for harmonic distortion and intermodulation measurements.  These filters are supplied in shielded metal cases to provide the best insulation against unwanted signals. Key parameters of these filters are:

Frequency Range : 1 KHz to 500 MHz

Impedance: 50 ohms

Maximum Insertion Loss: 1 dB

Maximum Ripple: 0.25 dB
