COM-24840

Balun Overview

The SparkFun Electronics COM-24840 is an RF balun transformer designed for the 2.4GHz to 2.5GHz frequency range, suitable for ISM band applications. It provides impedance transformation between unbalanced and balanced circuits with a 50/100 Ohm configuration. The component features a phase difference of 180° ±10° and a maximum insertion loss of 1.0dB. It is housed in a compact 0805 (2012 Metric) surface-mount package with six printed circuit board pads. The device is currently active and manufactured by SparkFun Electronics.

Balun Feature Summary

• Provides RF signal conversion between balanced and unbalanced lines within the 2.4GHz to 2.5GHz spectrum
• Ensures signal integrity through a specified 180-degree phase difference tolerance
• Facilitates impedance matching between 50 Ohm and 100 Ohm circuit sections
• Utilizes a low-profile surface-mount footprint for automated PCB assembly

Balun Applications

• Wireless sensor network transceivers operating in the 2.4GHz ISM band
• Bluetooth Low Energy (BLE) module interface circuits
• Wi-Fi enabled embedded system antenna interfaces
• Industrial telemetry radio front-end stages

Balun Procurement Notes

Verify the specific manufacturer part number COM-24840 against official SparkFun documentation to confirm the 0805 package and 2.4GHz-2.5GHz operational range. Ensure compatibility with the target impedance requirements of 50/100 Ohms before integration. Cross-reference the phase difference specification of 180° ±10° and insertion loss limits with system design constraints. Confirm the component status is active and check for any updated datasheet revisions that may affect performance parameters or pinout definitions.

Balun Selection Notes

Select this component when a dedicated balun is required for 2.4GHz wireless protocols such as Bluetooth or Zigbee. The 0805 package size offers a balance between handling capabilities and board space efficiency. Consider the 1.0dB maximum insertion loss when calculating overall link budget margins. The 50/100 Ohm impedance ratio suits specific differential line configurations common in legacy or specialized RF designs rather than standard single-ended transitions.

Balun Part Context

This component belongs to SparkFun's accessory and breakout ecosystem, often paired with microcontroller development boards. It serves as a passive RF building block for hobbyist and professional prototyping of wireless communication nodes. Unlike integrated transceivers, it focuses solely on signal conditioning and impedance transformation, requiring external active components for full functionality.
