The TCD-13-122-75X+ is a surface mount directional coupler designed for 75Ω systems operating from 5 to 1250 MHz, with a typical mainline loss of 1.2 dB and a coupling factor of 12.7 dB ±0.5 dB. It features a DB1627 case style measuring 4.06 × 3.81 × 4.83 mm, with an operating temperature range of -40°C to 85°C and a storage temperature range of -55°C to 100°C. The device offers high directivity, typically 11 to 20 dB across the band, and input/output return losses exceeding 17 dB. It is aqueous washable and supports external 75Ω termination. The pinout includes input, output, coupled, ground, and unused pins, with no internal termination. The part is protected by US Patent 6,140,887 and is suitable for DOCSIS®, CATV, and cellular applications.
