2.3 DESIGN
The design utilizes a low power oscillator VHF amplified to 100mW
of power and phase-locked with a chain to a reference divider quartz
oscillator. The 100mW signal is then applied to a 12 pole low pass
filter that produces RF final RF output. All this is housed in an metal
case fully screened to protect the user from direct contact with RF
voltages and to prevent unwanted emissions, local interference and
provide to the unit with sufficient RF immunity for the proper
operating in an industrial environment.
