PLOA

PLOD

Description

This is a line of fixed frequency phase-locked oscillators that use a high-Q coaxial resonator oscillator and either analog sampling phase detector techniques (Luff model PLOA) or digital techniques (Luff model PLOD)  to establish phase lock to the reference.

The PLOA configuration is used when the best possible spectral quality is needed.  The PLOA configuration has the limitation that the output frequency must be an integer factor of the input frequency.

The PLOD has a much more flexible frequency plan, however, the phase noise of the PLOD is not as low as that of the PLOA.

Both units are housed in a rugged low profile assembly and employ our unique manufacturing techniques that result in units of excellent value.
