Ultra Performance Requirement For A Digital Attenuators in MIMO Applications

Posted by Blaise Yen on June 6, 2017

Introduction         Digital Programmable Attenuators are routinely used in radio performance testing to simulate path loss. MIMO technology enables the use of multiple streams of data to boost throughput. The number of streams is also increasing from the 2×2 of only a few years ago to 8×8 and soon to be even higher. Multiple channel…

How to Select the Right Microwave Attenuator

Posted by Blaise Yen on May 23, 2017

Selecting the right microwave attenuator for RF testing applications can be a bit daunting. There are a number of device specifications that engineers need to consider, and buying a substandard or inadequate testing device (or even a fleet of devices) can be an expensive mistake. Before we get into characteristics, it’s worth covering briefly what…

Your Guide to Digital RF Attenuators

Posted by Blaise Yen on May 23, 2017

In this blog post, we’re going to dive a little bit deeper into the core capabilities of a digital RF attenuator to provide you with some touchstones when assessing their merits and utility in your own testing applications. Attenuators, as you probably already know, control the amplitude, or strength, a signal in a high-frequency RF…

The Benefits of Variable RF Attenuators

Posted by Blaise Yen on May 23, 2017

In testing applications where the power of a signal needs to be continuously or regularly varied, variable RF attenuators come into play. In these devices, the resistor networks commonly found in fixed or step attenuators tend to be swapped out for solid-state metal-oxide semiconductor field-effect transistors (MOSFETs) or PIN (so named because a p-type and…

Evaluating Programmable RF Attenuators

Posted by Blaise Yen on May 23, 2017

Programmable attenuators are a vital piece of equipment in almost every advanced RF testing environment, whether it’s a full-blown lab or a simple cube. They differ from fixed attenuators in that they’re able to produce different values of RF signal attenuation on demand, and they differ from basic variable or step attenuators because that value…

Selecting the Right RF Attenuator for Your Environment

Posted by Blaise Yen on April 25, 2017

In RF testing, precision is everything. That’s why any engineer will emphasize how essential it is to have the right tools for the job. Using the wrong kind of equipment makes about as much sense—and promises as much accuracy—as using pliers to drive in a screw. Although RF attenuators are slightly more complex than that,…
