Description

High Frequency RF Crossover

From DC - 40GHz | Knowles Part Number DDL10519

The use of complex multilayer printed circuit boards (PCBs) has become standard, even for the simplest of RF boards, in order to cross over an RF or digital trace. A less expensive, less complex alternative is the component style crossover device which can even eliminate the need for PCBs in some cases.

Current crossover devices available today in the market only operate up to ~6GHz. Not anymore! Knowles’ new, patented surface mount RF crossover component can operate from DC to 40GHz!

Our RF Crossover utilizes a new grooved ceramic channel which enables the product to crossover a top layer DC or RF trace, simplifying board routings and construction.

Features & Benefits:

• Wideband performacnce covering DC-40GHz
• Ease of implementation (compared to multilayer boards)
• Over 40dB isolation from DC-10GHZ and over 30dB isolation from 10-40GHz
• Over 20dB return loss from DC-10GHz and over 12dB return loss from 10-40GHz
• Small size L 0.15” x W 0.10” x H 0.02”

Applications:

• Aerospace
• Defense
• Telecom
• Radar
