Plug-in Diplexer 75Ω DPLC-4254A0+ DC to 1220 MHz (DC-42, 54-1220 MHz) The Big Deal • • • • • • • Plug-in design Field replaceable Low insertion loss Excellent return loss, 24 dB typ. Low group delay variation in passband Mirrored version available for ease of routing DOCSIS 3.1 standard CASE STYLE: QB2223 Product Overview DPLC-4254A0+ is a high performance field replaceable plug-in diplexer with the lowpass port at DC-42 MHz and highpass port at 54-1220 MHz. Excellent return loss combined with high out of channel rejection makes it a ideal part in cable TV and multiband radio systems Key Features Feature Advantages Low passband insertion loss Ensures low signal loss through both the channels. Excellent Stopband rejection Co-channel rejection of 50dB typical ensures unwanted spurious are eliminated. Excellent return loss at DC-42 and 54-1220 MHz This makes signal transmission with very less reflection and well-matched with the adjacent component used in the system. Notes A.
