The ISL55005, ISL55007, ISL55008 and ISL55009,
ISL55010, ISL55011 constitute a family of high performance
gain blocks featuring a Darlington configuration using high ft
transistors and excellent thermal performance. They are an
ideal choice for DVB-S LNB cable receiver applications.
ISL55005, ISL55007, ISL55008 offer higher OIP3
performance while the ISL55009, ISL55010, ISL55011 offer
lower operating supply currents.
ISL55005 and ISL55009 match a 75Ω source to a 50Ω load.
ISL55007 and ISL55010 match a 75Ω source to a 75Ω load.
ISL55008 and ISL55011 match a 50Ω source to a 50Ω load.
