EL4451C
Wideband Variable-Gain Amplifier Gain of 2
Applications Information
Contd
A voltage-controlled equalizer and cable driver
can be constructed so
Equalization and Line Driver Amplifier
4451 – 35
The main signal path is via the REF pin This
ensures maximum signal linearity while the mul-
tiplier input is used to allow a variable amount of
frequency-shaped input from R1 R2 and C For
optimum linearity the multiplier input is attenu-
ated by R1 and R2 This may not be necessary
depending on input signal amplitude and R1
might be set to 0 R1and R2 should be set to pro-
vide sufficient peaking depending on cable high-
frequency losses at maximum gain RF and RG
are chosen to provide the desired circuit gain in-
cluding backmatch resistor loss
