Question: Where are the transmitter characteristics specified for a User Equipment (UE) with a single or multiple transmit antenna(s), unless otherwise stated?
Option 1: At the baseband processor
Option 2: At the antenna connector of the UE
Option 3: At the power amplifier output
Option 4: At the duplexer input
Explanation: The transmitter characteristics are specified at a specific reference point to ensure consistent measurement and evaluation. In this case, the reference point is the antenna connector of the UE, which provides a standardized interface for measuring the transmitter's performance.
