Abstract: A transportable weather radar, including radar electronics functionally located above the elevational joint, a frame superstructure rotationally connected to an elevational assembly supporting the elevational joint, a rotational drive assembly mounted below and supporting the elevational assembly, and at least one harmonic drive for positioning the radar antenna. The radar includes a fiber optic rotary joint positioned above a slip ring assembly which is positioned within a lower portion of the elevational assembly so that as the elevational assembly rotates a fiber optic cable connected to the lower end of the fiber optic rotary joint is stationary relative to the rotating elevational assembly. The slip ring assembly permits electrical signals to traverse through traditional metal cables from the pedestal to the frame superstructure where electronics are held.

Abstract: A transportable weather radar having radar electronics functionally located above the elevational joint and a frame superstructure rotationally connected to the elevational joint onto which is mounted a parabolic radar antenna adapted for Doppler weather radar use. The radar has a rotational drive assembly mounted below and supporting the elevational joint and a harmonic drive unit positioned inside the elevational joint so that the antennae may be rotated without significant backlash during rotational changes. A hollow center in the rotational joint allows for the passing of electronics cable through the middle of the joint and down through rotating assemblies and to electronics in or adjacent to the radar pedestal.

Abstract: The controlling circuit element of a voltage controlled oscillator (VCO) for use in a phase lock loop (PLL) is a varactor connected between the terminals used to convey the power supply voltage and the frequency control voltage. The loop filter, implemented in a shunt configuration at the input of the VCO, is also connected between the power supply and frequency control voltage terminals. As a result, any variations in the power supply voltage appear at both terminals of the varactor due to the voltage coupling effect of the loop filter between the shared power supply and frequency control voltage terminals.

Abstract: An oscillator with oscillator and voltage control circuitry for generating an oscillation signal having an amplitude that is automatically controlled for a selectively minimized phase noise. Automatic level control is used for controlling the amplitude of the oscillation signal such that the phase noise of the oscillation signal can be maintained at some selected level, e.g., minimized. The minimum signal voltage appearing across the oscillation circuit is monitored for controlling the bias of the circuit to prevent it from entering a saturation state, thereby avoiding adverse loading effects responsible for degraded phase noise performance.

Abstract: A differential conversion circuit for converting an unbalanced signal to a balanced signal is provided. The differential conversion circuit is arranged with primarily passive components, and so avoids introducing noise or other disturbances to the signal. The differential conversion circuit has a terminal input for receiving an unbalanced signal that is related to a communication input signal. An inductor and a resonating capacitor connect to the terminal input, and a coupling capacitor connects to the inductor. One differential output line is provided by the resonating capacitor, while the other differential output line is provided by the coupling capacitor. The output from the capacitors is thereby a pair of lines that provide a balanced differential signal which is deliverable to a balanced load.
