Within an RF signal chain, there is often the need to provide some signal conditioning in incoming, outgoing, or through signals. One of the most needed signal conditioning methods is amplification of signal energy, which is the key function of RF Amplifiers. Signal amplification involves increasing the amplitude of a signal, this could imply voltage, ..

A Bidirectional Amplifier, or Bi-directional Amplifier (bda), is an active RF device that is widely used in a variety of telecommunication, radar, and other RF sensing applications. Though conceptually a Bidirectional Amplifier performs a relatively simple operation, the internal electronics can be somewhat complex. Moreover, many applications favor certain names and types of Bidirectional Amplifiers, ..

Waveguide amplifiers, or full-band/multi-band waveguide amplifiers, are amplifiers housed in assemblies that have either waveguide or coaxial interconnect. Though waveguide interconnect is more common for waveguide amplifiers, some waveguide amplifiers have coaxial interconnect instead, but still perform as specified over a given waveguide frequency band. The main feature of waveguide amplifiers is that they are ..

A class AB amplifier is a highly used amplifier design for high power RF applications, as well as other applications that require high power gain with minimal signal distortion. The main feature benefit is that Class AB amplifiers are biased so that the output current flows for less than one full-cycle of the input waveform, ..

Amplifiers are electronic devices that increase the power of a signal. The amount of amplification in an amplifier is measured by its gain, or the ratio of output voltage, current, or power to the input with a power gain greater than one. An RF amplifier is similar to an audio amplifier but with components suitable ..

Is many applications, amplifiers are used to increase the strength of a signal, while minimizing the distortion and noise without sacrificing efficiency. However, with most receiver systems, and other applications, achieving the highest signal power isn’t the goal. As receivers circuits are typically highly sensitive to input power, and can be desensitized or damaged if ..

A Bi-Directional amplifier (BDA) is a device that locates a wireless signal, amplifies it, and then rebroadcasts it throughout a building or area. The backbone of most range or signal extending technologies is a relatively simple dual amplifier device with an integrated low noise amplifier (LNA) and power amplifier (PA). The Bi-Directional amplifier either enables ..

Packaging dimensions, weight, pinouts and material construction are critical features of any RF amplifier. These factors heavily weigh into the cost and feasibility of using a particular amplifier in a given design. Regardless of electrical and RF performance, if an amplifier can’t fit into the required footprint, the device won’t be serviceable for that application. ..

The input and output power characteristics of an RF amplifier are dominant characteristics, as increasing signal strength is the primary purpose of an amplifier. An RF amplifier will be specified with a maximum and nominal range for input and output power based on certain conditions. These specifications will further extend to a maximum and nominal ..

We just launched a brand new rackmount variable gain RF amplifier with performance from 100 MHz to 18 GHz. This Pasternack 19-inch rack mounted RF amplifier is designed for lab use and various test and measurement applications. Normally this type of RF rack mount amplifier requires long lead-times for delivery often exceeding several months; however, ..
