Temperature variable attenuators deliver stable performance from -55 to +125 °C

April 23, 2025 By Redding Traiger

International Manufacturing Services, Inc. (IMS) is now producing Temperature Variable Attenuators (TVAs) for a wide range of applications to 20 GHz and beyond. Its new AV-0607-C TVAs are ideal for RF power amplifiers (PAs), broadcast equipment, and multiband communications systems. With their low-noise, thin-film construction, the TVAs exhibit decreasing attenuation with increasing temperature to help […]

What causes signal attenuation in a PCB and how can it be controlled?

January 3, 2023 By Jeff Shepard

Except for the most basic designs, system clock rates are inexorably creeping upward across a wide range of applications, from 5G telephony to automotive advanced driver assistance systems (ADAS), medical, industrial, and mil/aero systems. As frequencies rise into the GHz range, the need for impedance control to minimize signal attenuation and protect signal integrity gets […]

When to filter, attenuate, and equalize signals

December 22, 2022 By Jeff Shepard

Signal chain management is important in various applications like medical imaging, 5G communications, advanced driver assistance systems (ADAS), and a range of consumer, industrial, and military devices. Filters, attenuators, and equalizers are some of the tools designers have available to optimize signal chain operation. This FAQ begins by looking briefly at the definition of decibels […]

Optical attenuators and loopbacks, what’s the difference?

December 21, 2022 By Jeff Shepard

Fiber optic attenuators (optical attenuators) are used to reduce or control the energy of optical signals. They are used in optical communications systems to protect sensitive receivers or to modulate signals and for engineering evaluation, testing, and system validation. This FAQ reviews the basic operation of optical attenuators, looks at practical applications for optical attenuators, […]

Why use attenuators in quantum computers?

December 20, 2022 By Jeff Shepard

Quantum computers are cryogenically cooled because their quantum bits (qubits) are extremely delicate and sensitive to disruptions from even minute amounts of thermal noise, such as Johnson-Nyquist (J-N) noise. J-N noise is generated by the thermal agitation of electrons, regardless of any applied voltage, when the conductor is at equilibrium. Even small amounts of J-N […]

What kinds of attenuators are there?

December 19, 2022 By Jeff Shepard

Attenuators are often defined as electronic devices that reduce the power of a signal without introducing significant distortion. While that’s not incorrect, it’s also not complete. For example, optical attenuators can be based on fixed or variable neutral density (ND) filters and are largely mechanical constructions. This FAQ considers basic types of electronic attenuators. Other […]

What’s a logarithmic resistor ladder good for?

May 2, 2022 By Jeff Shepard

A logarithmic resistor ladder consists of a resistor string and switches designed to attenuate a signal. The state of the switches can be considered to represent a digital code proportional to the logarithm of the attenuation ratio. Logarithmic attenuation is useful when a large dynamic range is needed. Audio volume control and fading/balancing audio signals […]
