PDW07948

RF Power Dividers/Splitters Overview

The PDW07948 is a high-frequency Wilkinson power divider manufactured by Knowles Dielectric Labs. It operates within a frequency range of 6 GHz to 18 GHz, providing four-way signal splitting capabilities. The component features a minimum isolation of 16 dB and a return loss of 15 dB, with a maximum amplitude/phase imbalance of 3°. Insertion loss is specified at 1.2 dB. It utilizes low-loss, high-dielectric constant materials for temperature stability and integrates precision thin-film resistors. The device is housed in a compact 10-SMD no-lead surface mount package measuring 0.300 inches in length by 0.250 inches.

RF Power Dividers/Splitters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure the correct package variant and material specifications are selected. Confirm that the 10-SMD no-lead footprint matches the target PCB layout requirements. Cross-reference the electrical parameters, specifically the 16 dB isolation and 1.2 dB insertion loss, with system simulation results to guarantee compliance with the intended RF design constraints before finalizing procurement.

RF Power Dividers/Splitters Selection Notes

Select this component when a four-way split is required across the 6 GHz to 18 GHz spectrum. The choice is driven by the need for a compact SMD form factor that eliminates the requirement for discrete external resistors. Consider the 3° phase imbalance limit and 15 dB return loss specifications to ensure compatibility with sensitive receiver or transmitter chains where signal fidelity and impedance matching are critical for overall system performance.
