Narda 3045C

The Narda 3045C is a precision directional coupler engineered for accurate RF and microwave signal sampling and monitoring in the 7 to 12.4 GHz band. Available in three coupling configurations—10 dB, 20 dB, and 30 dB—the 3045C delivers stable performance across demanding test and measurement environments. Coupling variation remains within ±0.5 dB, with frequency sensitivity of ±0.25 dB, ensuring repeatable results. Directivity measures 15 dB. Insertion loss varies by model: the 3045C-10 presents 0.95 dB loss while the 3045C-30 achieves 0.35 dB. VSWR ranges from 1.25:1 to 1.30:1 depending on configuration.
