EHF-FD1621

Balun Overview

The EHF-FD1621 is a hybrid balun manufactured by Panasonic Electronic Components, designed for RF signal conversion applications. It operates within a frequency range of 1.1GHz to 1.45GHz. The device provides impedance transformation between unbalanced and balanced ports, specifically 50 Ohms and 200 Ohms respectively. Key electrical specifications include a maximum insertion loss of 1.0dB and a phase difference of 180° ±15°. The component is housed in a 1206 surface-mount package.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion with specified impedance matching
• Operates within the 1.1GHz to 1.45GHz frequency band
• Maintains low insertion loss characteristics for efficient signal transmission

Balun Applications

• RF front-end modules requiring impedance transformation
• Wireless communication systems operating in the specified UHF/SHF bands
• Balanced antenna interface circuits

Balun Procurement Notes

Verify RoHS compliance status carefully, as sources indicate this specific part may contain lead or be non-compliant depending on the revision. Confirm the exact datasheet version matches the required impedance and frequency parameters for your design. Ensure the 1206 package footprint aligns with your PCB layout constraints before finalizing procurement orders.

Balun Selection Notes

Select this component when a 50-ohm to 200-ohm impedance transformation is required within the 1.1-1.45GHz range. Consider the 1.0dB maximum insertion loss limit for system budget calculations. The 1206 package size offers a compact solution for space-constrained designs compared to larger through-hole alternatives.

Balun Part Context

This part belongs to the EHF-FD series of hybrid baluns from Panasonic. Similar models in the series, such as the EHF-FD1618, offer different frequency ranges and impedance configurations, such as 700MHz-1.3GHz with 50/50 Ohm matching. The EHF-FD1621 is distinct due to its specific 50/200 Ohm ratio and higher frequency operation.

Balun Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate other Panasonic EHF-FD series variants or third-party baluns that match the 1.1-1.45GHz range and 50/200 Ohm impedance requirements.
