LDPG-272-492+

RF Multiplexers Overview

The LDPG-272-492+ is a surface-mount LTCC diplexer designed for RF signal conditioning. It operates with two distinct frequency bands: a low band from DC to 2.7 GHz and a high band from 4.9 GHz to 5.75 GHz. The component maintains a standard 50 Ohm impedance across its ports. Key electrical specifications include a minimum high-band attenuation of 17 dB and a minimum low-band attenuation of 20 dB. High-band return loss is specified at a minimum of 14 dB, ensuring effective signal isolation between the designated passbands.
