UHF Radio

KySat-2 will be equipped with an Astronautical Development Lithium 1 UHF Radio.  As a receiver, the radio will receive RF signals from antennas and filter out the information.  As a transmitter, the radio will receive data from the C&DH and transmit it out as RF signals.  Communications with the C&DH will be performed using the UART protocol.  The radio will be directly connected to battery for transmitter and require 3.3V power from the EPS.  The antennas on the KySat-2 will have circular polarization to provide a constant RF signal despite satellite orientation.
