Notes: 1. TDMA spectral regrowth is measured with a spread spectrum input from a Marconi 2051 Signal Generator selecting the “Digital/Cellaular/NADC”
modulation system that produces ^π/4 DQPSK modulation with 24.30 kHz symbol rate and Root Nyquist filtering with alpha = 0.35.
This unit is to be mounted on a ground plane and thermal heat sink, with a maximum heat sink temperature of +85°C.
