Programmable Surface Acoustic Wave Oscillator
MetadataShow full item record
A programmable surface acoustic wave (SAW) delay line oscillator with a wide range of frequency variation is presented. The device consists of an amplifier with SAW delay line and a special phase shifter used as feedback elements. The delay line applied in this oscillator can be of single mode or multimode type. A number of frequencies within a given range may be adjusted by the programmable control circuit.
