The Tektronix H488  (P/N 155-0178-00,155-0178-05) is a horizontal output amplifier hybrid integrated circuit implemented as a thin-film ceramic hybrid in a custom "Hypcon" package.

It uses the ft doubler topology, has an input impedance of 50 Ω per side, and is designed to operate into a 365 Ω differential load. It has a current gain of 3.3 and is not back terminated.

The device uses T-coils at the input and inductive peaking at the output. Its rise time is approximately 0.5 ns.

It was designed by Dave Morgan and includes D156 transistor dies. The ft doubler section is built using SHFIII devices.
