Description
Surface Mount Package
SOT-363/SC70
Agilent’s ABA-51563 is an
economical, easy-to-use, inter-
nally 50-ohm matched silicon
monolithic broadband amplifier
that offers excellent gain and flat
broadband response from DC to
3.5 GHz. Packaged in an ultra-
miniature industry-standard
SOT-363 package, it requires half
the board space of a SOT-143
package.
• Unconditionally stable
• Single 5V supply (Id = 18 mA)
• Lead-free option available
Applications
• Amplifier for cellular, cordless,
special mobile radio, PCS, ISM,
wireless LAN, DBS, TVRO, and TV
tuner applications
