Wireless Device Essentials – KKT Trimmer, BKT RF MLCC, QKT Quartz

Wireless products—from compact remotes to WLAN nodes and IoT sensors—rely on three building blocks: tuning to hit the target frequency, filtering to keep signals clean, and a precise clock to stay in sync. Splitting those across vendors often adds qualification churn and lead-time variance.

Kingtronics provides a one-stop path: KKT for frequency trim (SMD trimmer capacitor), BKT for efficient RF filtering (High-Q MLCC), and QKT for stable timing (quartz crystal). Explore the product pages below.
