Mini-Circuits’ K1-BBFCG+ is a designer kit consisting of 10 tiny ceramic bandpass balun filter models from the BBFCG series, which cover a variety of wireless communications applications. 5 units are included per model, for a total of 50 units in the kit. BBFCG models provide low insertion loss, low phase unbalance (relative to 180°), and low amplitude unbalance. Fabricated using LTCC technology, the units come housed in a tiny, rugged ceramic package suitable for harsh operating environments.
