MOD 9 OBJ 3A

The frequencies sent from the down converter to the modem

• Intermediate Frequency (IF)

• Radio Frequency (RF)

• Amplitude Modulation (AM)

• Direct Current (DC)

In receive it receives the digital baseband signal from the modem

• Data Terminal Equipment (DTE)

• Network Interface Card (NIC)

• Central Processing Unit (CPU)

• Random Access Memory (RAM)

Used to amplify the radio frequency to a level suitable to reach the satellite

• Frequency Modulator

• Radio Transmitter

• High Powered Amplifier(HPA)

• Antenna Booster

Primary responsibility is to take the intermediate frequency given to it by the modem and translate it to a usable satellite radio frequency

• Down Converter

• Frequency Modulator

• Up Converter

• Amplifier

The radio frequency received from the assigned satellite

• Transmission

• Downlink

• Reception

• Amplitude

Used to pass the received signal from the satellite to the low noise amplifier

• Antenna

• Reflector

• Feed Horn

• Amplifier

Used to convey the transmit signal from the block up converter to the amplifier

• Fiber Optic Cable

• Ethernet Cable

• USB Cable

• Coaxial Cable

Used to control the total power output

• Regulation

• Attenuation

• Amplification

• Modulation

The reason why ground terminals often receive a week downlink signal from the satellite

• Atmospheric conditions

• Frequency of transmission

• Distance

• Angle of inclination

The component in the amplifier that heats up and amplifies the signal

• Tube

• Coil

• Resistor

• Transistor
