Zusammenfassung:	New ETSI and ITU regulations prescribe more stringent-rules for spectrum allocation in microwave frequency bands used for digital radio relay equipment. This implies usage of frequency-efficient modulation methods for data transmission. This paper deals with realization of intermediate frequency QPSK modulator employed in the RRU 13A digital microwave radio-relay link manufactured by Institute IMTEL.
