Figure 6-1 GSP-1620 Modem Temperature/Humidity Envelope

Thermal Radiation

The temperature profile shown in Figure 6-1 includes

temperature rise due to thermal radiation, solar radiation,

and other heat loads. The GSP-1620 modem dissipates heat

that is dependent on the mode and the transmit power. The

dissipated heat is the difference between the DC input power

and the RF transmitted power.
