Mini-Circuits’ SYDC-19-52VHP+ surface mount bi-directional coupler provides exception- ally high power handling up to 60W and low mainline loss of 0.3 dB for applications from 30 to 512 MHz. This model features a unique heat sinking design that enables reliable operation at high power without overheating, making it an ideal choice for systems where high power capability and small size are desired. The coupler features core and wire con- struction mounted on an 8 -lead printed laminate base with wraparound terminations for ex- cellent solderability. The unit measures 0.75 x 0.52 x 0.49″, accommodating dense circuit board layouts. Feature Advantages High power handling, 60W Usable in many systems with high-power requirements Low mainline loss, 0.08 dB Provides excellent through-path signal power transmission. Good directivity, up to 35 dB High directivity allows accurate signal sampling through the coupled port with minimal measurement error. Excellent return loss, up to 35 dB (input/output/coupling) Provides excellent matching in 50 systems with minimal signal reflection. Small size, 0.75 x 0.52 x 0.43″ Provides high power capability while saving space in systems with tight layouts. SYDC-19-52VHP+
