Calibrating tuners for Network Analyzers presents challenges due to high reflections and low losses, affecting S-parameter measurements. At Focus Microwaves, we advocate for TRL (Thru-Reflect-Line) calibration as essential for precise results, unlike the less reliable SOLT and ECal methods. Our comprehensive TRL calibration kits cover 0.3 to 110 GHz and support connector types including 7/16, N, APC-7, 3.5mm, 2.9mm, 2.4mm, 1.9mm, WR-15, and WR-10. Compatible with all commercial network analyzers, these kits ensure reliability and accuracy, crucial for dependable VNA measurements.

Discover precision phase reference solutions from Focus Microwaves, spanning frequencies from 100 MHz to 8 GHz, 30 GHz, and up to 67 GHz. Our phase reference units are indispensable for achieving precise phase calibration in RF and microwave measurements across a wide range of frequency bands.

SuperMini Board-to-Board solutions optimize interconnect performance for board-to-board stacking applications.

Available bullets enable board-to-board spacing as close as 3 mm, assuring transmission line dependability for tightly stacked PCBs. Low mating insertion force allows for an increased density of interconnections per board. Unique bullet design enables extended mating and de-mating cycles.

Focus Microwaves introduces a cutting-edge noise measurement system comprising three integral components: the Input Noise Module (INM), Output Noise Module (ONM), and Noise Module Controller (NMC). This system extracts precise noise parameters, offering rapid, stable measurements and optimized performance with dedicated software for calibration and analysis.
