Microwave Oscillator With Tm01.Delta. Dielectric Resonator

View page
US Patent:
45217467, Jun 4, 1985
Filed:
Aug 31, 1983
Appl. No.:
6/527953
Inventors:
Eugene J. Hwan - San Carlos CA
Darko Kajfez - Oxford MS
Assignee:
Harris Corporation - Melbourne FL
International Classification:
H01P 710
H03B 518
US Classification:
331 96
Abstract:
A microwave oscillator with TM01. delta. dielectric resonator is disclosed. The oscillator operates with a TM01. delta. mode as contrasted with prior art techniques of TE01. delta. mode. This provides for an improved tuning range in excess of 10% of the operating frequency.

Wide Bandwidth Loop In A Frequency Shift Keying (Fsk) System

View page
US Patent:
57063109, Jan 6, 1998
Filed:
Feb 14, 1995
Appl. No.:
8/388315
Inventors:
Han-chiu Wang - Palo Alto CA
Eugene Hwan - San Carlos CA
Assignee:
Digital Microwave Corporation - San Jose CA
International Classification:
H04K 102
H04L 7503
US Classification:
375296
Abstract:
A digital frequency shift keying (FSK) transmitter provides direct frequency modulation in a wide bandwidth loop. In one embodiment, a discriminator circuit recovers from the output signal of the transmitter a base band signal, which is then compared with the input base band signal to provide an error signal for controlling the output oscillator circuit. In another embodiment, the output oscillator is controlled by a phase detector detecting the phase difference between the base band modulating signal and the output signal of the transmitter. An additional narrow bandwidth loop can be added to compensate for frequency drift in the output oscillator due to temperature or other environmental changes.
