DEB-B055NC5S is a 5.50 GHz surface mount bandpass filter designed for precision RF signal filtering in microwave applications. The filter features a fully shielded ceramic construction with low-loss, temperature-stable materials that minimize performance variation over the operating temperature range of -55°C to +125°C. It provides a characteristic impedance of 50O with typical insertion loss of 2.0 dB across the 5.0–6.0 GHz passband, low-side rejection of 12–20 dB (DC–4.2 GHz), and high-side rejection of 40–45 dB (6.75–12.0 GHz). The compact surface mount package measures 0.350 × 0.200 × 0.090 inches (8.89 × 5.08 × 2.29 mm) with MSL1 moisture sensitivity rating and ENIG termination finish. This drop-in solution is ideal for wireless communications, radar systems, and satellite applications requiring highly repeatable, frequency-stable filtering performance.
