Additional Details

The 0900BL15C050 operates in the frequency range centered around 900 MHz. Specific impedance ratios may vary depending on the exact model. The balun is designed for automated assembly using standard SMT (Surface Mount Technology) processes. The insertion loss is typically less than 1 dB, and the return loss is greater than 15 dB. It's constructed using ceramic materials, ensuring high reliability and stability over a wide temperature range. It is often used near RF transceivers to properly interface single ended outputs from an RF IC to differential inputs of a receiver, or differential outputs of a transmitter to a single ended antenna.
