Abstract:

A packet radio has carrier frequencies which are harmonics of a reference frequency. A step recovery diode produces in effect all the harmonics. A digital to analog converter causes a voltage controlled oscillator to produce a frequency which is one of the carrier frequencies. A phase-lock loop locks in on this frequency. A separate harmonic identification circuit is used to determine which frequency the loop is locked to. If a different frequency is desired from that to which the loop is locked, a microprocessor will cause the voltage supplied to the VCO to be changed. Author
