•
Designed to work with the BCM4500 and BCM4201
satellite receivers
•
Operates across entire satellite L-band
frequency range
•
Extremely low phase noise for operation with 8PSK
modulation systems
•
Highly integrated solution minimizes design time and
system cost
•
Operates using single 3.3V supply to eliminate the need
for 5V
•
Complete reference design available to minimize
customer RF expertise requirement
