ADCB-20-82+ is a surface-mount, bi-directional coupler designed for 50Ω systems over the frequency range of 1 to 800 MHz. It features a coupling value of 20 dB with a flatness of ±0.2 dB from 1 to 400 MHz and ±0.2 dB from 400 to 800 MHz, and a mainline loss of 0.3 dB typical at 400 MHz. Directivity is 24.4 dB typical at 400 MHz and 15 dB typical at 800 MHz. Return loss exceeds 20 dB at frequencies up to 400 MHz. The device is housed in a case measuring 7.9 mm × 6.9 mm × 4.1 mm with a pin configuration supporting RF input, RF output, forward and reverse coupled ports, and ground connections. It operates from -40°C to 85°C and accepts up to 1 W input power above 10 MHz. The package is aqueous washable and complies with US patents 6,133,525 and 6,140,887.
ADCB-20-82+ is a surface mount, bi-directional coupler, operating over a wide frequency range, 1-800 MHz housed in a small case measuring 0.31” x 0.27” x 0.16” (7.9 mm x 6.9 mm x 4.1 mm). It uses square cores and a unique patented1 circuit design to achieve very flat coupling making it ideal for use in wideband applications.
