The DBTC-20-4-75X+ is a surface mount directional coupler for 75Ω systems, operating from 5 to 1250 MHz with a nominal coupling of 20.5 dB and coupling flatness of ±0.9 dB. It has a mainline loss of up to 1.5 dB across the band and a directivity ranging from 6 to 19 dB depending on frequency. The device maintains a VSWR of 1.4:1 up to 1000 MHz and supports input power up to 1.0 W above 500 MHz. Operable from -40°C to +85°C and stored from -55°C to +100°C, it uses an LTCC base with all-welded construction in a micro-miniature AT1667-1 case measuring 3.81 × 3.81 × 4.06 mm. This part is rated for CATV applications and is aqueous washable.
