2 Install the forward input equalizer specified by the design print in the forward
input equalizer slot. Or, install the correct inverse equalizer specified by the
design print for your system in the forward input equalizer slot. For a list of
available accessory pad values and part numbers, see Technical Information (on
page 93).
Note:
Be sure that all the pins on the forward input equalizer or inverse equalizer
bottom align with the pin holes in the equalizer slot, allowing the equalizer to
install flat against the amplifier module.
The same inverse equalizer is used for either 870 MHz or 1 GHz.
The locations for equalizers are approximately the same for all GainMaker
System Amplifier amplifiers. The illustration above shows a typical example.
The forward interstage equalizer is installed at the factory, and should not be
changed in the field. While it is a 1 GHz equalizer, it is appropriate for use in
both 1 GHz and 870 MHz system applications.
The plug-in interstage equalizer and an on-board interstage equalizer
combine to produce the total internal tilt for the station. The plug-in interstage
equalizer value is different from one type of amplifier to another by design, in
order to achieve optimum performance.
