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.
