Mini-Circuits BFCN-1690+ Ceramic Bandpass Filter
The Mini-Circuits BFCN-1690+ is a ceramic bandpass filter designed for harmonic rejection in transmitters and receivers. It features good VSWR (1.29:1 typ. @ passband), a small size (0.126 x .063 x .035), and temperature stability due to its LTCC construction. This filter is suitable for applications requiring precise frequency filtering within the 1570 to 1810 MHz range.
