Temperature Sensor Module
REV 1.13 (ASY 0183)
The Temperature Sensor module is a small board mounted to the main heatsink
of the amplifier/transmitter. The main purpose of the temperature sensor module
is to take temperature readings of the heatsink. The following is a block diagram
of the Temperature Sensor module:
The temperature sensor IC is U701 which, after it has taken a reading, relays the
digital information to the RF PCB module through J700. Also passing through
J700 is a driver disable signal coming from the RF PCB module. The
Temperature Sensor module simply takes this signal and passes it through to a
pad, where a wire connects it to the driver or first gain stage pallet.
In custom applications, there may be multiple temperature sensors installed onto
a heatsink or throughout the system.
