Description
M/A-COM's DS53-0005 is an IC-based monolithic power divider using M/A-COM's GMIC technology in a low cost SOIC-8 plastic package. This 3-way power divider is ideally suited for applications where small size, low insertion loss, superior phase/ amplitude tracking and low cost are required. Typical applications include personal communication systems and other communication applications where size and PCB real estate are at a premium. Available in tape and reel. The DS53-0005 is fabricated using a passiveintegrated circuit process. The process features fullchip passivation for increased performance and reliability.
