950MHz FET-Input Buffer with 75Ω Output
_______________General Description
The MAX4005 is a ±5V, single-ended unity-gain buffer
with a high-impedance JFET input, intended to drive a
75Ω load. A 75Ω thin-film output resistor is included on-
board to minimize reflections when driving a 75Ω load
through a transmission line of arbitrary length. Gain in
this configuration is 0.5.
