voltage gain is determined by R . With load resistance

of 1kΩ the single ended voltage gain is 45dB and with a

load resistance of 50Ω the voltage gain is 15dB (20log

compared with 400MHz for R = 50Ω. R is chosen to

give either the required bandwidth or voltage gain for the

circuit.

The SL6140 is an integrated broadband AGC amplifier,

designed on an advanced bipolar process. The

amplifier provides over 15dB of linear gain into 50Ω at

400MHz. Gain control is also provided with over 70dB

of dynamic range. The SL6140 offers over 45dB of

In any application, the substrate should be connected to

the most negative point in the circuit, usually to the same

point as pin 3.
