G3L-1900-31/G3L-1900-31-A Operation Manual

Section 1 General Description

1-1 Introduction

This manual contains information and procedures for the operation of the model G3L-1900-31
and G3L-1900-31-A Wideband (WCDMA) Multi-Carrier Power Amplifier (MCPA). The manual is
organized into the following sections and appendix.

Section 1 General Description
Section 2 Operation
Appendix A Specifications

1-2 General Description

The amplifiers are wideband, linear, feed-forward power amplifiers (WPAs) that operate in the 60
MHz frequency bandwidth from 1930 to 1990 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.
