Narda, an L-3 Communications company, introduced the model 4246B-10, a miniature stripline coaxial microwave coupler that delivers 10 dB of coupling from 6 to 18 GHz, has an extremely flat frequency response, and is designed to meet military requirements.
The model 4246B-10 handles 50 W of average power and 3 kW of peak power, has directivity of at least 15 dB, insertion loss of 2.5 dB or less, VSWR of 1.4:1, frequency sensitivity of +/-0.5 dB or better, and maximum deviation from nominal of +/11 dB. The compact module measures 1.4" x 0.66" x 0.42", weighs 0.9 oz. (25 g) and has female SMA connectors. The coupler meets military requirements for shock and vibration and has an operating temperature range of -54° to +105°C without performance degradation.
The model 4246B-10 stripline coupler is member of Narda’s “Maximally Flat” family of coaxial couplers, which includes models in the frequency range of 500 MHz to 18 GHz with coupling values of 6, 10, 20 and 30 dB.
