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
