1-2 General Description

The amplifiers are wideband, linear, feed-forward power amplifiers (WPAs) that operate in the 60
MHz frequency bandwidth from 2110 to 2170 MHz with an instantaneous bandwidth of 20 MHz.
The amplifier provides linear amplification for single or multi-carrier WCDMA signals. The amplifi­ers communicate with the base station via a TLCI control interface bus; passing alarm and meas­urement information to the base station and receiving control information from the base station.

1-3 Hardware Interface

There are three groups of interface connections located on the amplifier chassis. These are RF,
power, and control interface (TLCI bus) as described in the paragraphs that follow.

1-3.1 RF

The RF interface is located on the power amplifier front panel consists of the RF-In (TX-In) and
RF-Out (TX-Out) connectors as shown in Figure 1-1.

1-3.2 Power Supply

Power supply voltages (-48 VDC or 230 VAC) from the base station subrack are connected to the
amplifier via connector X3, pins A – D located on the power amplifier rear panel as shown in fig­ure 1-1. Table 1-1 lists the voltages and descriptions for each pin.
