1.2 Modules
The base station consists of a subrack with up to two physical transmit/
receive channels.
The single PMU (power management unit) supplies and manages power to
the whole subrack (refer to “Theory of Operation” on page 22). One reciter
and one PA (power amplifier) are needed for each physical transmit/receive
channel. There is also a front panel with user controls and fans. The
modules are interconnected at the front of the subrack. External
connections to the modules are located at the rear.
Modules come in different variants depending, for example, on the RF
band or the supply voltage.
Each module is inserted into the 4U subrack from the front and is secured
at the front with a metal clamp. Both clamp and module are easily removed
for rapid module replacement. The modules are secured laterally with
plastic guides that clip into the top and bottom of the subrack. These guides
can be easily repositioned to change the configuration of a subrack. The
heavier modules are also secured laterally by metal tabs at the rear of the
subrack.
The following provides a brief description of the available modules.
Subrack The 4U subrack is made of passivated steel and is designed to fit into a
standard 19 inch rack or cabinet. The subrack is fitted with an interconnect
board that connects the system control bus and power to the modules and
front panel. The position of a module in the subrack is defined by the socket
on the subrack interconnect board to which the module is connected by the
system control bus.

Front Panel The front panel is mounted onto the subrack with two quick-release
fasteners. It incorporates the indicator LEDs, four-line LCD display, user
controls, ambient temperature sensor and cooling fans.
The indicator LEDS allow some monitoring of the operational status of the
base station. The user controls and display allow the technician to
configure the IP address of each module. Refer to “Front Panel” on page 39
for more information.
The base stations have different front panel ducting arrangements
depending on PA type and power. Front panels may not be interchange-
able.
The microphone input and speaker are not currently used.
Reciter The reciter module comprises the
receiver, exciter and digital control
circuitry. The reciter provides the
Ethernet interface and system inputs
and outputs.

14 Description TB9300 Installation and Operation Manual
© Tait International Limited July 2019
Power Amplifier The PA amplifies the RF output from the reciter and is available in 50W
and 100W models.
The 50W model mounts vertically in the subrack, while the 100W model
mounts horizontally as it has a wider heatsink. The 100W PA is also fitted
with an airflow duct.
Both models are designed to operate on the 28VDC output provided by the
PMU.
Power Management
Unit
The PMU provides the 28VDC
power supply for the modules in the
subrack. It can operate on
120/230VAC 50/60Hz nominal, and
12, 24 or 48VDC nominal. The input
voltage can be AC, DC, or both AC
and DC, depending on the model. The
PMU also has an auxiliary DC output
of 13.65VDC, 27.3VDC, or
54.6VDC, depending on the model.

1.3 Mechanical Assembly
This section illustrates the main mechanical components of the base
station.
Figure 1.1 below shows the configuration for a typical dual 50W base
station. The subrack has six slots, numbered from right to left as viewed
from the front of the subrack. The PMU occupies slots 5 and 6, with the
reciters in slots 1 and 2. The two PAs are mounted vertically in slots 3 and
4 with the heatsinks facing each other. The airflow separator between the
PAs helps to direct the cooling airflow evenly through each heatsink. The
PMU and each pair of reciters and PAs have their own cooling fans.
The front panel can be easily removed from the subrack by undoing two
quick-release fasteners. Refer to “Replacing Modules” on page 106 for
more details.

1.5 Applications
The TB9300 is designed for operation in a Tait TN9300 DMR Tier 2
conventional radio network, a Tait TN9300 DMR Tier 3 trunked radio
network, an MPT-IP network, or as an analog conventional repeater.
TB9300 channel groups allow DMR simulcast and multicast operation
with receiver voting. With an external synchronization input, the TB9300
includes all voting and transmitter synchronization functions necessary.
Channel group operation applies to both trunked and conventional DMR
networks.
In a DMR Tier 3 trunked network the TB9300 operates as a traffic channel
or a control channel. With two logical channels for each radio frequency, a
single TB9300 base station can provide two traffic channels, two control
channels, or both a traffic channel and a control channel.
In an MPT network, the TB9300 operates as a control channel or as a traffic
channel. The TB9300 operates with a trunking node or in fallback
operation, both of which can be either trunked or conventional.
In analog operation the TB9300 operates as a conventional repeater with
CTCSS1or DCS subaudible signaling.
For more information, refer to the DMR System Manual.
