The YTFBP12R4/R8-7ID is a compact, high‑reliability thin‑film microstrip filter designed for microwave systems. Its small size and wide temperature tolerance make it suitable for microwave communications, radar, and electronic counter‑measure applications.
Key specifications include a 12.4 GHz center frequency, 12.0‑12.8 GHz passband, ≤2.5 dB insertion loss, and ≥40 dBc out‑of‑band suppression. The filter operates from –45 °C to +85 °C, supports up to 35 dBm input power, and uses a ceramic substrate with gold plating. Installation guidelines recommend a low‑stress conductive adhesive and a carrier material with a matching thermal expansion coefficient. This manual is written in Chinese.
