Attenuators

General Information

• MIL-A-3933 Qualified (QPL)

• dc - 4, dc - 8, dc - 12.4, dc - 18 and dc - 26 GHz Performance

• Small Size, Light Weight, Rugged Construction

• Average Power available up to 20 Watts

• Meets MIL-E-5400 and MIL-16400 Environmental Requirements

• SMA, BMA, N, TNC, BNC, SC, 3.5mm, and 7mm Connector Configurations

Attenuators are passive components designed for the purpose of reducing the input power in a matched transmission line system by a predictable amount on a linear basis. Midwest Microwave offers this complete product line of fixed coaxial attenuators, ruggedly designed for system or laboratory test use. These units exhibit low VSWR and high accuracy attenuation performance over the temperature range of -54C to +125C and meet the environmental requirements of MIL-E-5400 and MIL-E-16400. Medium power attenuators with average power levels of up to 20 Watts are available in up to 30 dB levels in .5 dB increments providing broadband performance and low frequency sensitivity while exhibiting very stable operation over temperature extremes. Standard cataloge units are available off the shelf for immediate delivery and special units can be custom designed by Midwest's engineering staff to accomodate unique system needs.

All Midwest Attenuators are completely manufactured in house and are 100% tested to insure only the highest quality performance whether for military or space use or for commercial applications.

Attenuators

Attenuation - The technical term is most often used in

connection with loss or insertion loss in a transmission line. Insertion loss is a combination of two types of losses; impedance mismatch loss (reflective) and attenuation loss (dissipative). Mismatchloss is the ratio of power that would be absorbed by a unit or device under test , if it were perfectly impedance matched, to the actual power absorbed by thedevice. Attenuation is the ratio of power into a component to the power out under impedance matched conditions, and represents the actual power dissipated within the component. Thereby,Insertionlossistheratioofthepower delivered to a matched load by a matched generator before and after the insertion of a component into the transmission line. When a component is perfectly matched to the transmission line and to the load, the mismatch loss is zero and the insertion loss is the same as the attenuation.

Average Power - The maximum average (cw) power is

the maximum input power specified and applied for one hour minimum at the specified temperature of 25 degrees C with the output terminated in a matched impedance such that the specified properties of the attenuator will not be altered or changed after the unit is returned to ambient temperature at a power level that is 20 dB below the maximum specified input power. If the attenuator is operated at higher temperatures then it is necessary to derate the power rating accordingly. The derating curve and specifications shown below describes this specifically.

Definition of Parameters

Precise Attenuator Assembly assures high performance

Peak Power - The maximum peak power at a pulse width

or duty cycle of 5 microseconds together with the average power when applied for a minimum period of one hour with the output terminated with a matched load will not damage or permanantly alter the specified properties of the attenuator.

Temperature Coefficient - The maximum change of

insertion loss in dB per degree C from 20 C over the maximum operating temperature range. To obtain the change in insertion loss, multiply the temperature coefficient by the temperature change and then by the value in dB of the attenuator.

Flange Mount type Attenuators are useful in many system or test instrument requirements where it is necessary to pass a signal through a panel and also take advantage of the opportunity to insert an attenuator while saving valuable space and weight. These units possess the same high performance characteristics as the standard 290 series.

The units are manufactured using rugged stainless steel construction and are designed to operate under very hostile environmental conditions.

SMA Connector - Attenuators

Flange Mounted - Integrated Design

• DC - 18 GHz Performance

• Tab, Slot, or Rod Contact for Microstrip use

• Interchangeable Transition Contact Pins

• Reduces Package Size and Weight

This series of SMA flange mounted Connector-Attenuators are ideally suited for use on microstrip packages where size and weight are a consideration.By combining the Attenuator and the launching Connector, space and weight as well as cost savings is accomplished.The resistive film circuit is designed to improve reliability and lower mismatch losses by eliminating the need for separate coaxial components.The units exhibit low VSWR and are ruggedly constructed of stainless steel and are temperature stabilized for use in hostile environments.

Attenuators

Type N Precision 1-18 GHz Performance

This series of Lossy Line Attenuators are very useful for a variety of test bench requirements. The lossy line is the simplest, most basic type of coaxial attenuator. The lossy line in these attenuators is actually the center conductor of a simple coaxial structure. The lossy line possesses some basic advantages over conventional attenuators in that they exhibit low VSWR characteristics that improve as frequency increases and are also very useful where phase tracking is important.
