What is isolation in RF?

An RF Switch or Microwave Switch is a device to route high frequency signals through transmission paths. RF (radio frequency) and microwave switches are used extensively in microwave test systems for signal routing between instruments and devices under test (DUT).
A.

What is the cause of insertion loss?

Excessive insertion loss can also be caused by poorly terminated connectors / plugs. A poor connection can add significant insertion loss. However, impurities in the copper cable can also cause insertion loss failures; again this typically happens on one pair only.
  • What is insertion loss in noise?

    Transmission loss (TL) in duct acoustics, together with insertion loss (IL), describes the acoustic performances of a muffler like system. It is frequently used in the industry areas such as muffler manufacturers and NVH department of automobile manufacturers.
  • What is the loss of reflection?

    In telecommunications, reflection loss occurs on a line which results in part of the energy being reflected back to the source. This can occur: At a discontinuity or impedance mismatch, e.g., in a transmission line, the ratio of the incident power to the reflected power. Reflection loss is usually expressed in dB.
  • What causes return loss on Cat 6?

    There are two major causes of RL in a network: discontinuities and impedance mismatches. Discontinuities occur at connections where cable is terminated to plugs or jacks and within the plug/jack connection itself. A discontinuity can also occur if a cable is bent too much, kinked or otherwise damaged.
B.

What is the difference between attenuation and insertion loss?

Insertion loss, also referred to as attenuation, refers to the loss of signal strength at the far end of a line compared to the signal that was introduced into the line. Insertion loss is usually expressed in decibels dB with a minus sign. Insertion loss increases with distance and frequency.
  • What is a duct silencer?

    Duct Silencers: Commercial – Industrial – HVAC. Silencers or Duct Silencers are an engineered product specifically designed to control airborne noise in ducts, openings in buildings, enclosures, or from equipment. They may also be referred to as industrial sound attenuators.
  • What is noise attenuation?

    Acoustic attenuation is a measure of the energy loss of sound propagation in media. Most media have viscosity, and are therefore not ideal media. When sound propagates in such media, there is always thermal consumption of energy caused by viscosity.
  • What is sound dampening material?

    When constructing a vehicle which includes soundproofing, a panel damping material is fitted which reduces the vibration of the vehicles body panels when they are excited by one of the many high energy sound sources caused when the vehicle is in use.
C.

What is RF return loss?

In telecommunications, return loss is the loss of power in the signal returned/reflected by a discontinuity in a transmission line or optical fiber. This discontinuity can be a mismatch with the terminating load or with a device inserted in the line. It is usually expressed as a ratio in decibels (dB);
  • What is distance to fault?

    Distance To Fault (DTF) is a performance verification and failure analysis tool used for antenna and transmission line service and maintenance. It uses the Frequency Domain Reflectometry (FDR) measurement technique.
  • What is the incident power?

    Incident power means a power that is not expressly granted but which exists for the accomplishment of an express purpose. It is also called as incidental power.
  • What is transmission loss of sound?

    Transmission loss is the number of sound decibels that are stopped by a wall or other structure at a given frequency. In the graph below, the green line represents the transmission loss of a wall at different frequencies.
