Design Features:

In selecting a design approach, foremost consideration was given to

phase noise performance and switching speed requirements.

A multi-loop design was chosen over a single loop configuration to

meet the resolution criterion. An output loop frequency range of 1

to 2 GHz is beat down to a narrower VHF range using a stepped LO

where a low noise variable frequency reference is generated. The

LO comprises a 100 MHz crystal oscillator and amplifier driving a

step-recovery diode comb generator, and exhibits a phase noise

level that is at least 3 dB below the system noise specification.
