The T2000 radio is made up of two modules, the RF module and the control module.
The RF module consists of an RF PCB unique to each frequency band with common
plug-in IF and TCXO/Tx audio PCBs, determining the frequency stability and reference
frequency. The control module consists of a logic PCB and a control head PCB. Each con-
trol module is unique to each T2000 model, i.e. T2010, T2015, T2020, T203X, T2040 or
T2050.

The following circuit blocks are located in the RF module:

• The synthesiser, containing the

- Tx/Rx VCO
- plug-in TCXO and Tx audio PCB
- Tx/Rx switching.

• The regulators and audio power amplifier.

• The receiver, containing the

- front end
- mixer
- noise blanker
- mute circuit
- RSSI
- plug-in IF PCB.

• The exciter, RF power amplifier and power control circuit.

The following circuit blocks are located in the control module:

• The microprocessor control circuitry.

• Audio  processing.

• Control  head.

• Options connectors (refer to Section 5.9, “Options Interface Specifications”).
