-The '''155-0181-00''' is a Tek-made Input Amplifier integrated circuit in a [[Hypcon]] package.
+The '''155-0181-00''' (H500) is a Tek-made Input Amplifier thin-film circuit (using an [[M199]] amplifier die) in a [[Hypcon]] package.  It was designed by [[John Addis]] and uses the "[[Transit frequency doubler|f<sub>t</sub> doubler]]" circuit patented by [[Carl Battjes]].
-It uses the "[[Transit frequency doubler|f<sub>t</sub> doubler]]" circuit patented by [[Carl Battjes]].
+The circuit has a single-ended 50 Ω input and push-pull outputs with a gain of up to 3.55 into a push-pull 50 Ω load.
+Gain may be varied from 3.55 to 0 and inverted to -3.55 by adjusting the ratio of two DC currents.
+At full gain, the risetime is 180 ps or less, but lower at reduced gain.
