ADC-20-4-75+ — Overview
ADC-20-4-75+ by Mini-Circuits is a component in the 20 dB Directional Coupler (5 to 1250 MHz, 75 ohm) category, supplied by Shenzhen Jinteng Electronics Technology Co., Ltd. (JTDZ Tech) — an independent distributor serving OEMs, ODMs and EMS providers worldwide.
The ADC-20-4-75+ is a surface-mount 20 dB directional coupler designed for 75 ohm systems over 5 to 1250 MHz, with 19.7 dB nominal coupling and excellent +/-0.15 dB coupling flatness. Mainline loss is 0.5 dB typical below 870 MHz and directivity is 23 dB typical, suiting it to cable TV and broadband communications equipment where a sample of the forward signal is needed. It comes in Mini-Circuits' CD542 transformer-based package and handles 1 W input.

Parameters above are transcribed from the manufacturer datasheet for reference only. Confirm the current datasheet revision and your application conditions before design-in.
Note: Correction to the brief: ADC-20-4-75+ is NOT a 4-way power splitter - the '4' is a package/series designator. Official datasheet confirms it is a 20 dB directional coupler (5-1250 MHz, 75 ohm, 1 W, CD542). Pins: 1 = input, 6 = output, 3 = coupled, 2 = ground, 4 = external 75 ohm termination, 5 = isolate (do not use).
