Description
M/A-COM’s DS52-0002 is an IC-based monolithic power
divider in a low cost SOIC-8 plastic package. This 2-wa y 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 base station switching
networks and other communication applications where size and
PCB real estate are a premium. Available in tape and reel.
The DS52-0002 is fabricated using a passive-integrated circuit
process. The process features full-chip passivation for increased
performance and reliabilit y.
