The DBTC-16-5-75X+ is a surface mount directional coupler designed for 75Ω systems across 5 to 1500 MHz, with a nominal coupling of 16 dB. It features a micro miniature AT1667-1 case measuring 3.81 x 3.81 x 4.06 mm, with a total thickness of 0.33 mm. Mainline loss ranges from 1.08 dB to 1.9 dB depending on frequency, and directivity exceeds 19 dB from 500 to 1500 MHz. The device supports input power levels up to 1 W and operates reliably from -40°C to +85°C. It uses an LTCC base with all-welded construction, aqueous washable, and includes internal DC grounding. VSWR remains below 1.9:1 across the band. Pin connections are labeled for input, output, coupled, ground, and an unused isolate terminal.
