Toner Cable HEA-37-1GHZ User Manual

1 GHZ, 2 Way, GaAs Power Doubling Headend Amplifier, 38 dB Gain

This rack mount amplifier is specifically designed as a headend amplifier to be used in analog or digital headends after
combining of the various signals. The HEA-37 features a single output on the rear which incorporates both the forward
path output and the reverse path input. The HEA-37 then features an internal diplex filter which provides a separate for­ward input connector and reverse output connector. The headend amplifier features midstage gain and slope controls as
well as plug in pads and equalizers on the forward path. The reverse path has a separate gain control along with an
input plug in attenuator (pad). The headend amplifier also has a passive/active reverse feature which is user selected by
means of a jumper.
