Mechanically Adjustable RF Attenuator
Variable attenuators provide continuously or step-adjustable loss to set path gain or emulate fading while maintaining good return loss. They are used for AGC loops and test fixtures, specified by range, flatness, insertion loss, and power handling. EM‑based RF digital twin capturing RF IC behavior across substrates, layouts, and transitions. We offer a robust portfolio of in-stock, adjustable RF attenuators and phase shifters for multiple applications, including test instrumentation, cellular communication, wireless communications, satellite communication and more. RF attenuators are devices used to reduce the power level of radio. Planar Monolithics (PMI) offers the highest quality RF and Microwave, Solid State digital and analog controlled attenuators for commercial, industrial, and military applications. 015 dB and operating frequency ranges up to 50 GHz in Octave. Over 400 coaxial, surface mount, and MMIC attenuator models for 50-Ohm & 75- Ohm system including fixed attenuators, high-power attenuators, digital step / programmable attenuators, voltage variable attenuators and more! Input power up to 2W Max.

Fiber Optic Cables and Radio
In the area of Wireless Communications one main application is to facilitate access, such as and WiFi simultaneously from the same antenna. In other words, radio signals are carried over fiber-optic cable. Thus, a single antenna can receive any and all radio signals (5G, Wifi, cell, etc.) carried over a single-fiber cable to a central location where equipment then converts the signals; this is opposed to the traditional way where each protocol type (5G, WiFi, cell) requires separate equipment at the loc.

Experimental Results of FBG Fiber Bragg Grating Frequency Measurement
In this work, we investigate the sensing performance of Fiber Bragg Gratings (FBGs) engineered to operate near EPs through precise structural tuning. By aligning the reflection spectrum edges with the EP condition, significant sensitivity enhancement is achieved under a power. Abstract—Exceptional points (EPs), intrinsic to non-Hermitian systems, exhibit singular spectral responses with extreme sen-sitivity to external perturbations, offering new opportunities for precision sensing. These microscopic structures within optical fibers have become the bedrock of cutting-edge sensor. Basically, Fiber Optic Bragg Sensors are strain-measuring devices and therefore provide many of the advan-tages of the well known metal foil strain gages.
