Mini-Circuits’ HFHKI-7300+ is a miniature low temperature co-fired ceramic (LTCC) high pass filter with a 7900 to 17,500 MHz passband that supports a wide range of microwave applications. Housed in a compact 1210 package, the device incorporates an integrated interposer optimized for CPWG surface-mount attachment, simplifying PCB integration and ensuring consistent RF performance. The LTCC fabrication process ensures stable electrical performance and high reliability under demanding environmental conditions. Its monolithic structure minimizes intrinsic non-linearities and supports wide, multi-octave passband performance
