1-2 General Description

The NTGS86AB amplifier module is a CDMA signal source, linear, single-channel power ampli-

fier (SCPA) module that operates in the 25 MHz frequency band from 869 MHz to 894 MHz. The

amplifier output is typically 25 watts with a gain range between 41 and 45 dB. The amplifier is de-

signed to be mounted in an enclosure with EMI containment. Its flat base plate allows for mount-

ing on a flat thermal-absorbing surface to provide adequate heat dissipation.

As shown in figure 1-1, each amplifier module has an RF input, RF output, and RF sample con-

nectors, as well as an 18-pin power, alarm, and control interface connector that allows the host

system to provide power and monitor the amplifier module performance. Primary power for the

amplifier is +26 Vdc.

Physical dimensions of the amplifier module are shown in figure 1-2.

1-3 Functional & Physical Specifications

Functional and physical specifications for the amplifier are listed in table 1-1.
