Planar transmission lines are used to carry a variety of analog, RF, and digital signals on insulative, planar substrates from kilohertz to hundreds of gigahertz frequencies. Planar transmission lines are constructed of one or more layers of metal traces with one or more parallel metal traces. There are several common types of planar transmission lines: ..

RF Diplexers and Duplexers are very common RF components in transmitters, receiver, and transceiver circuits for communications, radar, and other sensing applications. As the terms are similar, they are sometimes mistakenly used interchangeably, which isn’t appropriate. Diplexers and Duplexers perform very different functions, though they are located in similar areas in a circuit block diagram. ..

In the world of high-speed communication and signal transmission, choosing the right medium can make or break system performance. Two of the most widely used transmission technologies—RF (Radio Frequency) cables and fiber optic cables—serve distinct roles in modern infrastructure. Whether you’re designing a wireless backhaul, a satellite ground station, or a data center interconnect, understanding the strengths and limitations of each ..

Designing for Harsh Environments? Start with MIL-DTL-38999.  Pasternack’s latest technical resource, “Primer on MIL-DTL-38999 Connectors and Contacts,” offers engineers and designers a comprehensive overview of one of the most trusted interconnect standards used in military, aerospace, and high-reliability environments. This detailed white paper explores the evolution of the MIL-DTL-38999 standard, connector series types (I–IV), materials ..

A Centigrade and Fahrenheit converter is an essential tool in the world of RF, microwave, and millimeter-wave engineering. It’s a world where temperature stability is crucial to the performance of both active and passive components, and a Centigrade and Fahrenheit converter can help ensure such stability. Whether you’re working with antennas, amplifiers, or oscillators, understanding ..

Planar transmission lines are used to carry a variety of analog, RF, and digital signals on insulative, planar substrates from kilohertz to hundreds of gigahertz frequencies. Planar transmission lines are constructed of one or more layers of conductive traces, possibly with adjacent conductive structures, with dielectric layers providing insolation between the conductive structures. Planar transmission ..

RF power amplifiers typically have an input, output, and power supply rails. These rails can be either positive, negative, or dual positive and negative voltages. The input, output, and power supply rails all have recommended operating ranges of power, voltage, and current. This range is specified to nominal operation in what the manufacturer was able, ..

Pasternack has a milestone anniversary this year! Fifty years later, Pasternack products are as relevant and renowned as ever, and there’s no slowing down. To celebrate this momentous occasion, we recently had the opportunity take a trip down memory lane and learn the history of the brand from Murray Pasternack, the founder of Pasternack. Read ..

In an ideal RF system, all of the energy from the RF source is transferred to the load. An example of this would be a transmitter delivering a signal to an antenna with the interconnect between the two signal chain components operating at 100% efficiency. Clearly, this isn’t the case, and factors like impedance mismatch ..

Dielectrics are one of the three main categories of electrical materials, the other two being conductors and semiconductors. Common dielectrics used in electronic systems are ceramics, glasses, gemstones, and polymers. Dielectrics, or insulators, are described as being very poor electrical conductors, and unlike conductors, allow for electrical fields to pass through them. However, the electric fields ..
