Description
M/A-COM's DS55-0002 is an IC- based monolithic power divider using M/A-COM's GMIC technology in low cost QSOP-20 plastic packages. This 5-way power divider is ideally suited for applications where PCB real estate is at a premium and part count reduction and cost are critical. Typical applications include base station switching networks and other cellular equipment, including subscriber units. Available in tape and reel. The DS55-0002 is fabricated using a passive-integrated circuit process. The process features full chip passivation for increased performance and reliability.
