Rf Digital Phase Shift Modulators

US Patent:
5148128, Sep 15, 1992
Filed:
Oct 25, 1991
Appl. No.:
7/782932
Inventors:
Shamsur R. Mazumder - Northborough MA
Assignee:
Raytheon Company - Lexington MA
International Classification:
H04L 2700
US Classification:
332103
Abstract:
A BPSK (Binary-Phase-Shift-Keying) modulator having reduced amplitude and phase errors includes two non-ideal N. degree. -bit phase shifters disposed between two 3 dB quadrature couplers to perform out-of-phase combining. When the two phase bits are alternately switched between a reference state and a signal state being N. degree. out of phase with respect to the reference by the cancellation, a 180. degree. binary phase shift keying modulator having reduced amplitude and phase errors relative to the individual phase shifters is provided.
