TDK Couplers

TDK Couplers

TDK’s HHM2xxx series multilayer directional couplers are used for signal monitoring and signal reporting without interrupting the main system power path. TDK’s couplers utilize a Low Temperature Co-fired Ceramic (LTCC) process and offer low insertion loss and high isolation. Couplers are available in a wide range of configurations with frequencies ranging from 450MHz to 5.95GHz and dimensions as small as 0.6 x 0. X 0.5 x 0.3mm to as large as 1.6 x 0.8 x 0.6mm. They are ideal for use in MIMO and CA designs for signal monitoring and controlling. Applications include WLAN, LTE, GSM/cellular and other frequencies where signal monitoring is required.
