70-MHz Solid-State Frequency Modulator

This report describes the development of a wide-band frequency-modulated oscillator with the following design goals: 1) direct modulation at a center frequency of 70 MHz; 2) instantaneous frequency deviation-±10 MHz; 3) linearity-within ±1 percent to ±10 MHz; 4) deviation rate (baseband response)-±0.5 dB from 100 Hz to 10 MHz; 5) provision for automatic frequency control.
