Product Overview
The HFCG-3500+ is a high pass filter designed for a wide range of applications, featuring a passband from 3900 MHz to 16500 MHz. Its strategically constructed layout results in a typical insertion loss of 1 dB across a broad spectrum. Housed in a compact 0805 ceramic form factor with wraparound terminations, this filter is ideal for dense PCB layouts, minimizing performance variations due to parasitics. The filter offers advantages such as a small size (2.0 mm x 1.25 mm), excellent solderability, a rugged LTCC construction suitable for demanding environments, and an ultra-wide passband.
