50Ω
5 to 2250 MHz
The Big Deal
• Wideband, 5 to 2250 MHz
• Flat coupling, 0.8 dB
• RF power handling up to 1W
CASE STYLE: DB1627
Product Overview
Mini-Circuits’ TCD-12-222X+ surface mount directional coupler provides 12.6 dB nominal coupling with
excellent flatness from 5 to 2250 MHz, supporting a wide variety of applications including VHF/UHF,
CATV, cellular and more. This model provides low mainline loss, high directivity and excellent return loss.
The coupler is built with core and wire construction mounted on a 6-lead plastic base (0.16 x 0.15 x 0.16”)
and includes Mini-Circuits’ TopHat® feature for faster, more accurate pick-and-place assembly.
