PRECISION FILTERS FOR
TESTING A-D CONVERTERS & AMPLIFIERS

  • LOW PASS

  • HIGH PASS

  • BAND PASS

  • NOTCH

  • DIPLEXERS

Precision Signal Conditioning for High Performance Testing Applications 

This family of filters is designed 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. Improves selectivity and dynamic range of all spectrum analyzers for harmonic distortion and intermodulation measurements. These extremely low distortion Lowpass, Highpass, Bandpass and Band Reject filters in conjunction with diplexers for better impedance matching are used to clean any signal source or test generator by removing all harmonics of the test signal that would interfere with test results.
Features
  •  Frequency range 1KHz to 500MHz
  •  Harmonic distortion less than -100 dB
  •  Low intermodulation distortion
  •  Low insertion loss
  •  Input signals to over 10 volts
  •  Passive Device
  •  50 Ohms matches all test generators and signal sources
  •  Supplied in shielded metal cases
  •  BNC and SMA connectors available
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. Improves selectivity and dynamic range of all spectrum analyzers for harmonic distortion and intermodulation measurements.
ORDERING PROCEDURE

LP – LOWPASS
HP – HIGHPASS
BP – BANDPASS
NT – NOTCH
DP – DIPLEXER

 Fundamental Frequency can be any 4-digit number

From 1.00 KHz to 500 MHz. “P” represents the decimal point.

ORDERING EXAMPLES: 

LPS0P001B  = LOWPASS FILTER FOR 1KHz FUNDAMENTAL
                            FREQUENCY WITH BNC CONNECTORS

HPS10P00S = HIGHPASS FILTER FOR 10MHz FUNDAMENTAL
                            FREQUENCY WITH SMA CONNECTORS

BPS100P0N = BANDPASS FILTER FOR 100MHZ FUNDAMENTAL
                           FREQUENCY WITH TYPE N CONNECTORS

NTS25P30B = NOTCH FILTER FOR 25.3MHz FUNDAMENTAL
                           FREQUENCY BNC CONNECTORS

DPS183P5S = DIPLEXER WITH 183.5MHz CROSS OVER
                            FREQUENCY WITH SMA CONNECTORS

The above ordering information is for single or unbalanced filters. For applications that require differential filters contact our Sales Department @ (516) 248-8080. By Fax @ (516) 747-6724 or by e-mail sales@allenavionics.com

LOW PASS FILTERS are designed to pass the fundamental frequency and attenuate all harmonics over 95dB.

HIGH PASS FILTERS are designed to attenuate the fundamental frequency a minimum of 95dB and pass all higher harmonics.

BAND PASS FILTERS provide over 95dB attenuation at all harmonics.

NOTCH FILTERS are designed to remove the fundamental frequency on the input to spectrum analyzer.

DIPLEXERS provide two outputs.
                        The Low Pass Output passes the fundamental frequency and attenuates the harmonics.
                        The High Pass Output provides a path for all harmonics from the generator.
