INTRODUCTION
1.1 Overview
The CPI MPA (Medium Power Amplifier) Hub Mounts are
designed for satellite communication earth stations, satellite news
gathering vehicles, and flyaway applications. The key feature of
these amplifiers permits direct mounting to antenna structures,
thereby eliminating transmission line losses encountered in
conventional remotely mounted arrangements. For this reason,
these amplifiers are referred to as “MPA Hub Mount Amplifiers.”
Table 1-1 shows the model numbers, frequency ranges, and power
outputs of these amplifiers. Figure 1-1 is a photograph of an MPA.
All models have the same appearance.
Table 1-1. MPA Hub Mount Amplifiers
Model Number
Frequency Range
(GHz)
Rated Power
(Watts)
T04UO 12.75 to 14.5 GHz 400 W
T04CO 5.85 to 7.1 GHz 400W
By industry convention, the rated power of an amplifier is the
output power of the high power-amplifying component, a traveling
wave tube (TWT). The output power available to the user at the
amplifier output flange is lower.
