PDW11598

RF Power Dividers/Splitters Overview

The PDW11598 is a high-frequency surface-mount Wilkinson power divider manufactured by Knowles Dielectric Labs. It provides six-way signal splitting across a broadband frequency range of 6 GHz to 18 GHz. The device utilizes low-loss, high-dielectric-constant materials for compact integration and temperature stability. Key electrical specifications include a minimum isolation of 15 dB, a typical return loss of 14 dB, and an amplitude/phase imbalance of 6 degrees. It features a 7-SMD no-lead package suitable for SMT assembly.

RF Power Dividers/Splitters Procurement Notes

Verify the specific suffix (e.g., -T) against the required packaging configuration, as standard and tape-and-reel variants may differ in handling. Confirm that the 7-SMD no-lead footprint matches the target PCB layout. Ensure the operating environment remains within the specified thermal limits to maintain dielectric stability and impedance matching characteristics during operation.

RF Power Dividers/Splitters Selection Notes

Select this component when a wide bandwidth from 6 GHz to 18 GHz is required for multi-channel signal distribution. The integrated resistor design eliminates the need for external components, simplifying the circuit layout. Consider the 7-SMD package size for board space optimization. Verify that the 15 dB isolation and 14 dB return loss meet the system's noise and reflection requirements.
