Mini-Circuits RF Directional Coupler - TCD-17-282X+ TCD-17-282X+

The TCD-17-282X+ is a surface mount RF directional coupler designed for a frequency range of 5 to 2850 MHz, offering a nominal coupling of 17 dB with excellent flatness. It features low mainline loss, with typical values of 0.7 dB up to 950 MHz and 1.9 dB at 2850 MHz, making it suitable for applications requiring efficient signal transmission. The coupler exhibits high directivity ranging from 10 to 25 dB, which allows for accurate signal sampling with minimal measurement error. Return loss values are also favorable, ranging from 14 to 22 dB across input, output, and coupling ports, ensuring good matching for 50,Ѷ systems. The device is capable of handling input power of 1W from 100 to 2850 MHz and 0.5W from 5 to 100 MHz, making it versatile for various high-power applications. It is built with a core and wire construction on a compact 6-lead plastic base, measuring 0.16 x 0.15 x 0.16 inches, and includes a TopHat¬Æ feature for improved pick-and-place assembly accuracy. The operational temperature range is from -40¬8C to 85¬8C, with a storage temperature range of -55¬8C to 100¬8C. This coupler is suitable for use in VHF/UHF, cellular, SatCom, and other RF applications.
