100 MHz frequency source with selectable internal amplitude modulation

100 MHz frequency source with selectable internal amplitude modulation

The Saronix oscillator has an open emitter output. When the 330 Ohm load resistor on the output is grounded, the RF out of the oscillator increases. Modulation is affected by driving the MPSH34 on and off to switch the 330 Ohm load resistor.
