The 2450BM14A0002 is a miniature balanced to unbalanced (Balun) transformer from Johanson Technology. It is specifically designed for impedance matching and signal balancing in applications operating within the 2.4 GHz to 2.5 GHz ISM band, which includes Wi-Fi (IEEE 802.11 b/g/n) and Bluetooth. This component facilitates efficient signal transfer between balanced circuits (such as differential amplifiers or antennas) and unbalanced circuits (like single-ended transceivers).

Applications

• Wi-Fi (IEEE 802.11 b/g/n) devices
• Bluetooth devices
• Zigbee applications
• Wireless LAN (WLAN) systems
• ISM band transceivers

Features

• Surface Mount Device (SMD)
• Compact size
• Balanced to Unbalanced (Balun) functionality
• 2.4 GHz to 2.5 GHz frequency range
• Low insertion loss
• Excellent amplitude and phase balance

Benefits

• Improved signal integrity: The balun provides impedance matching, minimizing signal reflections and losses, resulting in improved signal quality.
• Reduced noise: Balanced signaling reduces common-mode noise, enhancing the signal-to-noise ratio in sensitive receiver circuits.
