Introduction to RF & Microwave Substrates & Base Materials The term “substrate” can be somewhat confusing the context of RF/Microwave devices, components, and applications. A substrate can generally be anything from the insulative material used to develop a semiconductor or film (thick-film or thin-film circuits or components), or the structural material of printed circuit boards...

Roundup of RF Transistor Types, Semiconductors, and Configurations The growing number of RF, microwave, and millimeter-wave applications has led to a growth in the number of RF transistor types, semiconductors, and configurations being used today. Future developments on these technologies are also ongoing, as competition in wireless communications, satellite communications, radar, sensing, test and measurement,...

What are Metamaterials and How Do They Relate to Antennas? Metamaterials are an increasingly researched topic, especially where it pertains to modern antenna structures. However, there is a lot of confusion of exactly what metamaterials are and how they are involved in the development of antennas. To put it simply, metamaterials are material and structure...

Note on GaN HEMT Amplifier Soft Compression Class III-V semiconductors, such as gallium arsenide (GaAs) and gallium nitride (GaN) have become commonplace solid state technologies for low noise amplifiers and high power amplifiers from frequencies ranging from several hundred megahertz to over 100 GHz. For high power applications, GaN high electron mobility devices (HEMTs) are...

RF Transformer Tidbits RF Transformers are two, or more, port passive devices with a wide range of uses for many RF applications. One of the most common uses of an RF transformer is the Balun, which provides efficient coupling between unbalanced transmission circuits and balanced circuits. Other common uses are for impedance matching between circuits...

Voltage Controlled Oscillator Primer Voltage Controlled Oscillators (VCOs) are a key component to many tunable communications, radio, radar, sensing, and measurement systems. Essentially, a VCO is an oscillator that can be controlled by an input voltage, usually analog. Hence, adjusting the tuning voltage across its range also changes the VCOs output RF signal, proportionally. VCOs...

Pasternack Debuts New Line of High Frequency Couplers with Low Insertion Loss and Low Return Loss New Couplers Operate in the High Frequency Range of 26.5 GHz to 67 GHz IRVINE, Calif. (August 1, 2019) - Pasternack, an Infinite Electronics brand and a leading provider of RF, microwave and millimeter wave products, has launched a...

Coaxial and Waveguide Rotary Joints Rotary joints, unlike typical adapters, have the ability to rotate about the axis perpendicular to the wave propagation direction. While maintaining transmission properties, these joints can rotate freely 360 degrees. This type of joint is necessary for any application that has a rotating section, such as a rotary antenna (air...

Pasternack Launches New MIL-DTL-22641 Aluminum Waveguide to Coax Adapters Aluminum Waveguide to Coax Adapters Offer Frequency Ranges of 1.7 GHz to 26.5 GHz IRVINE, Calif. (July 18, 2019) - Pasternack, an Infinite Electronics brand and a leading provider of RF, microwave and millimeter wave products, has launched a new series of waveguide to coax adapters that...
