RF sensing and communication applications often involve very weak signal levels. It is often necessary to use RF Amplifiers to increase the gain, or signal level, of these signals in order to digitize them or otherwise condition these signals to usable levels. However, there are a few trade-offs to consider when increasing a signal’s power ..

At first look, there are many different types of RF amplifiers, and it could be overwhelming to go from the specs you need to narrowing down what RF amplifier type is the best fit. Most RF amplifier types came about from the specification requirements of common transceiver, receiver, transmitter, radar, and modulation circuits and system-level ..

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 are amplifiers specifically designed to be housed within a waveguide assembly. This provides some intrinsic advantages and trade-offs compared with coaxial connectorized amplifier assemblies or pallet amplifiers. Given that waveguide amplifiers are designed to directly mate with a given waveguide size and type, they are innately banded, as the waveguide has a limited ..

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, ..

IMS 2015 video discussing largest in-stock inventory of connectorized RF, microwave and millimeter wave amplifiers at Pasternack. At the booth during IMS 2015, Tim Galla briefly discusses why Pasternack now has the largest inventory of coaxial RF, microwave and millimeter wave amplifiers available for same-day shipping. The video can be found here: http://www.engineeringtv.com/video/Pasternack-Offers-RF-Microwave See IMS ..
