1 GENERAL INFORMATION T2130 1.4 PRINCIPLE OF OPERATION AND BLOCK DIAGRAM SAILOR Compact HF SSB T2130 is a 250W PEP transmitter in SAILOR Compact HF SSB Programme 2000. It contains following circuits. POWER AMPLIFIER The power amplifier is a push-pull amplifier. The input signal from RE2100 is fed through a TX/RX switch on the output filter unit to the input of the power amplifier. The signal is amplified to approx. 280W PEP. The bias to the pre-driver, driver, and PA can be switched off from the TX microprocessor. When this is done, the output power will be attenuated more than 60 dB. OUTPUT FILTER The output filter consists of six lowpass filters, a directional coupler, a tune/transmit switch, and a TX/RX switch. From the power amplifier the signal is fed to a lowpass filter, which attenuates all harmonics. Then the signal passes a directional coupler, which gives information about the standing wave ratio to the TXprocessor unit. After the directional coupler the signal is fed to a drive/transmit switch. In position drive the output power is fed to a 50 ohm load. This load is used to set the output power to the correct value. After this switch the signal is fed to the TX/RX switch. In position RX the signal from the aerial coupler AT2110 or the aerial is fed directly to RE2100. In position TX the signal from RE2100 is fed to the input of the power amplifier and the output power is fed to the aerial coupler AT2110 or the aerial. TX PROCESSOR The processor takes care of controlling the power amplifier, output filters, aerial coupler AT2110, and communication with RE2100. From RE2100 the TX-processor receives information about frequency and receive/transmit mode. The TX-processor gives information to RE2100 about tuning/tune ready and attenuator setting. During tune-up the TX-processor is controlling the aerial coupler. It tunes for best standing wave ratio measured with the directional coupler on the output filter module. During transmit the TX-processor is checking the temperature of the PA-transistors, supply voltage, and stating wave ratio. From these data the TX processor calculates the max. permissible power, and then sends this information to the RE2100, where the processor unit sets the attenuator in the exciter unit to the correct value. POWER SUPPLY This unit consists of two power supplies and the AF-amplifier. The 24V DC is first fed to a relay which switches off/on the supply to the power supplies. One switch mode power supply is used to generate ±18V and 9V for all small signal circuits in T2130 and RE2100. The supply for the power amplifier and the AF-amplifier passes through a serial regulator, which limits the voltage to max. 28V. PAGE 1-4 9345
1 GENERAL INFORMATION T2130 CONNECTION BOARD The connection board is the interface to the aerial coupler AT2110, HF SSB RE2100, 24V mains, and other units e.g. loudspeaker, muting of ext. receivers etc. All input and output from ext. equipment are made through an optocoupler, a relay, or a transformer.
