  • RF Test Equipment Series: RF Test Probes & Antennas

    11/14/2019

    Outside of coaxial and waveguide interconnect, there are two other main methods of interacting with DUT during RF/microwave/millimeter-wave testing. These methods include surface probes that connect to component leads or microstrip pads, and antennas design for test purposes. Test probes and antennas are used for very different types of testing, but both are crucial in ..

    J Standard Soldering (IPC J-STD-001 and IPC J-STD-006) For Coaxial Cable Assemblies

    01/31/2019

    Standardization and quality control surrounding solder and soldering practices for military electronics has been around for decades. Initially, the United States military used MIL-STD-454, MIL-S-45743, DOD-STD-2000, and MIL-STD-2000 to define soldering practices before merging with industry standards, such as IPC J-STD-001 and IPC J-STD-006. These standards attempt to ensure that the end results of a ..

    Basics of Surge Protectors and Lightning Arrestors for Telecommunications and RF Applications

    12/06/2018

    Who dares thwart the power of Zeus? Surge protectors and lightning arrestors are devices that protect electrical components from a temporary rise in voltage and current on an electrical circuit.  Surge protectors are designed to protect electronic equipment from power surges and voltage spikes by diverting the excess current from the transient event or surge ..

    Types of Antennas at the RF and Microwave Frequency

    09/06/2018

    Monopole The monopole is a resonant antenna and the length of the antenna is determined by the wavelength of the radio waves being received and transmitted. A monopole antenna is usually made of a single conductor mounted over the ground with one side of the feedline from the receiver or transmitter connected to the conductor ..

    Bits on Baluns

    06/07/2018

    Part 1: What is a balun, what does a balun do, and when is a balun needed? What is a balun? A balun (mashup of balanced and unbalanced) is a three-port device, or a type of broadband RF transmission line transformer, with a matched input and differential output that is used to connect balanced transmission ..

    More Details on Zero Bias Schottky Diode Detectors

    05/31/2018

    The Schottky diode, named after German physicist Walter H. Schottky, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action.  Compared with the point contact diode used in similar applications, the zero bias Schottky diode has a wider ..

    Exploring Types of RF Microwave Detectors

    05/24/2018

    A radio frequency (RF) microwave detector, also known as RF power detector or RF responding detector, is a two-terminal device used to detect, and in some way, measure or convert an RF signal. As the receiving element, an RF detector is used in converting amplitude-modulated microwave signals to baseband (or video) signals in either a ..

    Introduction to Gunn Diode Oscillators

    05/03/2018

    A Gunn diode, though very unlike other common semiconductor diodes, is a transferred electron device (TED) that presents a negative resistance after its threshold voltage is adequately exceeded. The controllable negative resistance properties of a Gunn Diode allows it to be used as a microwave oscillator, and these devices are often used in microwave communications, ..

    Handheld Analyzers and Cable Testers Require Rugged RF Test Cables Part 1

    04/19/2018

    The most recent handheld RF analyzers and cable testers for telecommunications are multi-functional instruments rich with features, and offer near-laboratory grade performance. This is extremely impressive considering many of these testers, which operate as network analyzers, spectrum analyzers, fault testers, signal generators, power meters, modulation analyzers, amongst other features, can be slung over a shoulder ..

    What are the ISM Bands, and What Are They Used For?

    03/22/2018

    The Industrial, Scientific, and Medical (ISM) frequency bands are designated radio frequency bands as defined by the ITU Radio Regulations. These frequency bands were set aside for RF use for purposes other than telecommunications. Hence, using the ISM bands for telecommunications is possible, but telecommunications devices using these frequencies must be able to withstand the ..
