Wideband, log periodic, directional antennas handle bandwidths of 600 to 6,000 MHz

August 23, 2022 By Redding Traiger

Fairview Microwave has expanded its line of wideband, log periodic antennas that operate from 600 to 6,000 MHz for point-to-point wireless communications. Fairview’s new, outdoor-rated, directional antennas function as boosters where the existing cellular signal is weak and needs to reach longer distances. This makes them ideal for strengthening 5G, 4G, LTE, CMDA, LoRA, IoT, and Wi-Fi signals. […]

What can you make with MEMS technology?

August 22, 2022 By Jeff Shepard

Microelectromechanical systems (MEMS) has several names, including micro-electro-mechanical systems, and micromechatronic systems. In Japan, MEMS is called micromachines, while in Europe, it’s referred to as microsystem technology (MST). Whatever name that’s used, MEMS devices are made using components measuring from 1 to 100 μm (0.001 to 0.1 mm), with MEMS devices ranging from 20 μm […]

Oven-controlled Xtal oscillators sync to 1 pps input, output

May 11, 2022 By Redding Traiger

IQD launched the IQCM-200, a disciplined OCXO, incorporating sync to a 1 PPS (pulse per second) input as well as a 1 PPS output. The IQCM-200 is part of a series of disciplined OCXOs available from IQD. This particular model is the smallest sized OCXO capable of achieving a holdover capability of 1.5µs over 24 […]

What’s a logarithmic resistor ladder good for?

May 2, 2022 By Jeff Shepard

A logarithmic resistor ladder consists of a resistor string and switches designed to attenuate a signal. The state of the switches can be considered to represent a digital code proportional to the logarithm of the attenuation ratio. Logarithmic attenuation is useful when a large dynamic range is needed. Audio volume control and fading/balancing audio signals […]

What are reflectionless filters? Part 1: context

March 16, 2022 By Bill Schweber

filters

Standard filters reflect unwanted stopband energy, but reflectionless filters present a seamless impedance across both stopband and passband which greatly improves performance of the RF signal chain. Filters are an inherent, inescapable, necessary component in electrical and electronic circuits. Modern systems would be impractical and likely impossible without filters, whether at low frequencies down to […]

3D printing for 5G systems

August 10, 2021 By Jeff Shepard

MIMO antennas, waveguides, traveling wave tubes, and RF substrates are fabricated using various 3D printing technologies. For example, 3D printing has been used to produce highly dense and integrated waveguide signal interconnects modules in a single monolithic unit. By printing the waveguide modules in one component, the part count was significantly reduced from tens or […]

What is passive intermodulation?

July 23, 2021 By Jeff Shepard

PIM setup

Passive intermodulation (PIM) is a pernicious and destructive phenomenon for cellular network operators. PIM shows up as a set of unwanted signals created by mixing two or more strong RF signals. Mixing generally produces the sum and difference frequencies of the two transmit signals F1 and F2. These signals are F1 + F2 and F1 […]
