RP-SMA to MHF4 Antenna Pigtail: Connect Your M.2 Wi-Fi or 5G Module to an External Antenna
Open up almost any modern connected device (a mini-PC, a 5G router, an industrial IoT gateway, a drone) and you'll find the same small problem repeated everywhere: the radio lives on an M.2 card with an antenna receptacle the size of a grain … More

MMCX Connectors Explained: Applications, Ratings & Cable Options
A GPS receiver board is ready, but the antenna cable must turn beneath a low enclosure cover. A larger threaded connector will not fit, and pulling the cable sideways would load the PCB. This is the kind of problem an MMCX connector can solve: a … More

RG316 Coaxial Cable: Complete Specs, Applications & Assembly Guide
A 300 mm antenna pigtail fits neatly inside your enclosure. Then the lid goes on, the cable folds against a bulkhead connector, and the measured return loss changes. The cable was selected by name, but the assembly was never specified as an electri… More

What Is the Maximum Frequency of RG316 Cable?
A designer routes a 5.8 GHz Wi-Fi radio to a panel antenna with 0.5 m of RG316 and the link budget comes up 2 dB short. The datasheet said RG316 is good to 3 GHz, so was the cable a bad choice, or was the datasheet figure never a hard limit? Both a… More

How to Clean and Care for RF Connectors (and When to Retire Them)
A lab runs the same VNA test cable for eight months. Return loss at 12 GHz creeps from 22 dB to 16 dB, the team recalibrates twice, and finally someone looks at the connector under a loupe. A flake of dried flux and a shiny scar on the outer contac… More
