The DBTC-10-4-75LX+ is a surface mount directional coupler designed for 75Ω systems with a nominal coupling of 10.5 dB over a frequency range of 5 to 1000 MHz. It features a micro miniature AT1642 case measuring 4.22 × 3.81 × 3.94 mm with pin connections for input, output, coupled, ground, and an unused isolate port. The device exhibits a mainline loss of 1.3 to 2.0 dB, coupling flatness of ±0.7 dB, directivity of at least 13 dB, and a VSWR of 1.3:1. It operates from -40°C to +85°C, is constructed with an LTCC base and all-welded components, and is aqueous washable.
