CHA5051-QDG
7-16GHz Medium Power Amplifier
Proposed assembly board "96270B" for the 24L-QFN4x4 products characterization.
Compatible with the proposed footprint. Based on typically Ro4003 / 8mils or equivalent. Using a microstrip to coplanar transition to access the package. Recommended for the implementation of this product on a module board.
-
The SMD leadless package has been designed for high volume surface mount PCB assembly process. A typical footprint is proposed for the PCB (motherboard) in the previous drawing. For the mounting process standard techniques involving solder paste and a suitable reflow process can be used.
