HFCU-223+

Overview

The HFCU-223+ is a miniature low temperature co-fired ceramic (LTCC) high pass filter manufactured by Mini-Circuits. It operates within a frequency range of 22,800 to 39,000 MHz with a center frequency of 30,900 MHz and a bandwidth of 16,200 MHz. The device features an insertion loss between 2.4 and 3.2 dB and supports a power handling capacity of 7 W. Designed for surface mount technology, it utilizes a 1812 (4532 metric) package and maintains a standard impedance of 50 Ohms.
