In the world of electromagnetic waves and wireless communication, understanding the relationship between frequency and wavelength is crucial. Whether you’re working with radio frequencies, microwaves, or optical signals, knowing how to find frequency from wavelength can help you design and troubleshoot wireless systems, antennas, and transmission lines. This blog will walk you through the process ..

VHF/UHF stands for very high frequency and ultra-high frequency, respectively. These frequency designations are in both the ITU and IEEE radar bands, but in this case we are discussing IEEE radar bands VHF and UHF, 30 MHz to 300 MHz and 300 MHz to 1000 MHz in the US. This is an important note, as ..

A Waveguide Magic Tee is a 180-degree hybrid power divider with 4 ports made from a single waveguide structure. The Magic Tee has been around for over 70 years and was a product of development during World-War II. The structure of a Magic Tee is a combination of an E-plane waveguide arm meeting a H-plane ..

In reality, all types of RF antennas have some degree of directionality. However, there are certain antenna designs and types that are particularly directional compared to other antenna types. A Directional Antenna is useful in applications where it is desirable to receive a signal from a specific direction of origin or otherwise transmit a signal ..

SMA Coaxial Connectors, or just SMAs, are one of the most common coaxial connector types used throughout the RF, microwave, and even millimeter-wave (mmW) industries. SMA stands for subminiature version A and was developed in the 1960s. The interface dimensions and other aspects of the SMA connector are detailed in MIL-STD-348 and was originally designed ..

RF Coaxial Cable Assemblies are used in virtually all environments where wireless systems are deployed. Coaxial cable assemblies are integral internal parts of many wireless systems, and they are also used as interconnects between systems. These cable assemblies are often anywhere from a few inches long to hundreds of feet in length. This range of ..

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 ..

The dominant use of coaxial cable in RF & Microwave applications is as a transmission line. Coaxial cables are extremely useful transmission lines as the coaxial nature of the transmission line provides relatively efficient transmission from DC to a cut-off frequency, which is a function of the geometries of the coaxial components of the cable. ..

An Antenna Downtilt and Coverage Calculator, or Antenna Tilt Calculator, aids the user by providing an approximate downward angle at which to install a directional antenna to reach desired signal strength and coverage between a transmitter and receiver at different heights and some distance away. An example use case is when a cell-tower directional transceiver ..
