I need more information about the use of the ADL5565 amplifier up to 4.5GHz,
information about noise figure, 1dB compression point and any other parameters
that could show me it's behavior up to 4.5GHz. The datasheet only provides this
information up to 1GHz.

 

Although the ADL5565 has a wide bandwidth, the part really isn’t useful at the
higher frequencies. The Output Voltage Swing X Gain Bandwidth Product limits
the maximum output voltage swing to 0.44 V p-p at 4.5 GHz. (see absolute max
ratings in datasheet). In order to achieve the necessary distortion performance
at IF frequencies, it was necessary to have a very wide bandwidth.
