Design approaches to the Low Frequency Array (LOFAR) active antenna amplifier Wim van Cappellen and Dion Kant ASTRON, Netherlands Foundation for Research in Astronomy The Low Frequency Array (LOFAR) is a radio telescope that will open up a hardly explo red part of the spectrum range for astronomy. LOFAR will operate between 10 and 200 MHz. Due to its advanced concept it will provide unique arc se
