Narda 3002-30

The Narda 3002-30 is a coaxial directional coupler engineered for precise forward and reflected power measurement in RF and microwave systems. Operating across 950 MHz to 2 GHz, it delivers a fixed 30 dB coupling value with ±1.2 dB variation, enabling accurate signal sampling without mechanical tuning. The device combines low insertion loss of 0.2 dB with 30 dB directivity, making it suitable for industrial automation, motion control, and demanding RF measurement applications requiring both commercial and military-grade performance.
