Surface Mount • Excellent Power Handling, 4W • Wide Bandwidth, 700-3500 MHz • Small Size, 3.1 x 3.0 x 1.6mm Product Overview Mini-Circuits D17W+ is a MMIC Directional Coupler designed for applications from 700 to 3500 MHz. This model provides excellent power handling up to 4W in a tiny device package (3.1 x 3.0 x 1.6 mm). A built-in 50Ω termination on the isolated port simplifies circuit design and reduces component count. Manufactured using Silicon IPD technology, this model provides a high level of ESD protection and excellent reliability. Allows a single component to be used in multiple narrowband applications reducing component count. Low insertion loss, 0.2 - 0.6 dB including coupling loss Can be used for sampling power amplifier output with minimal loss. Excellent power handling; 4W (IN-OUT) Ideal for sampling transmitter output power. Good directivity minimizes coupling of reverse power and enables accurate sampling of the thru-signal. High operating temperature -40 to 105°C Operation up to 105°C allows the Coupler to be used near power amplifiers with minimal change in performance. Excellent ESD Class 1B (500 to <1000V)-HBM Class M3 (200 to <400V)-MM Rugged ESD design prevents ESD related failures. Notes A.
