A problematic base station can be replaced, but a cable and antenna system is not so easy to replace. This article covers fundamentals of cable and antenna analysis measurements: return loss, cable loss, and distance-to-fault (DTF).
The waveguide, along with the coaxial line, is one of the most important transmission media in any modern RF, microwave and millimeter-wave component, subassembly, and system. Due to its metal tubing configuration, the waveguide tends to be heavy and bulky, especially in low microwave frequencies. However, it is always a preferred transmission means when performance and high power are priorities. In millimeter-wave bands, it is especially true that the waveguide is widely used, and engineers will pay high attention to loss. This article will discuss the use of waveguide connectors, and present viable solutions, such as the Uni-Guide™.
Carlisle Interconnect Technologies offers UTiFLEX-HF coaxial cables designed to provide a solid cable assembly solution operating from DC to 65 GHz range for 50 Ohm applications where flexibility is a key requirement. The cable solutions feature 70% VP cables and premium 80-85% VP cables for when critical applications need a phase stable solution with minimal signal loss.
Fairview Microwave introduces a new series of rugged, portable, phase stable RF analyzer cable assemblies ideal for handheld network analyzers, base station analyzers, portable spectrum analyzers, field testing, tower measurements, distance-to-fault measurement, and site maintenance applications. These 19 analyzers deliver excellent amplitude, phase stability with flexure, and operate at a maximum of 27 GHz.

HUBER+SUHNER offers the MXPM multicoax solution supporting measurements up to 70 GHz (with an option to 80 GHz). The MXPM unit guarantees satisfactory performance and affordability with its high density pitch (2.54 mm, 0.1 inch) and a user friendly magnet mount connection.
HUBER+SUHNER offers the RADOX® 125 as a highly flexible single core cable solution for industrial applications. With a concentric stranded conductor design, this core cable is easy to process and strip, leading to greater savings in installation costs and overall reduction in the related overheads.
The Minibend CTR/Mini141 CT family of phase invariant cable assemblies is designed for phase critical applications requiring precision electrical length connectivity. The cables combine the flexibility of the HUBER+SUHNER Astrolab bend-to-the-end connector termination technology with industry leading phase noise vs. temperature performance.
HUBER+SUHNER’s RADOX®, or “radiation X-linked” technology, describes the process of crosslinking thermoplastic polymers by means of electron beams. This technology is used to improve the thermal, mechanical, and chemical properties of cable insulation materials. RADOX® cables do not melt, possess better abrasion resistance and greater cut resistance than conventional cables and, even with thinner insulation, are much more resistant to various environmental factors.
JMA Wireless, a global leader of wireless communications solutions, has partnered with HUBER+SUHNER, a leading supplier in FO and RF connectivity for the global communication market, to provide the most economical hybrid power plus fiber Cell Site Cabling Solution (FttA+PttA) on the market.
