Network Analyzers Use High Frequency Reed Relays in Their Attenuator Circuits
Introduction
Network analyzers are widely used in the RF frequency realm, whether it is measuring the characteristics in the analog continuous wave high frequencies, or measuring the rise and fall times of fast digital pulses. With the rapid rise of cell phone usage over the last 15 years and wireless technology expanding into every ‘nook and cranny’ of our lives, network analyzers have skyrocketed in usage. Within the network analyzer’s circuitry, the need to attenuate RF signals is necessary; and MEDER’s high frequency reed relays with life times in the billions of operations have found their niche.
