Surface mount directional coupler designed for 75Ω CATV and wire-line broadband access applications, operating from 5 to 1200 MHz with a nominal coupling of 9.3±0.5 dB and coupling flatness of ±0.7 dB. The device features a case style AT1030 with dimensions 4.22 x 3.81 x 3.94 mm, solderable leads, and an operating temperature range of -40°C to +85°C. Mainline loss reaches 2.4 dB at 1200 MHz, directivity ranges from 12 to 20 dB across the band, and maximum input power is 0.5 W. Constructed with an LTCC base and all-welded design, it supports aqueous washable processes.
