= +5V, load resistance = 500Ω on each output to ground, MGS = 011, LNP = 22dB and f
IN
= 5MHz, unless otherwise noted.
The input to the preamp (LNP) is single-ended, and the output from the VCA is single-ended, unless otherwise noted. This results in a 6dB reduction in signal
amplitude compared to differential operation.
