  The series of phase locked coaxial resonator oscillators have been designed for use in commercialand military systems where demanding performance, high reliability and cost are critical. This family of products take advantage of the small size, low phase noise and high efficiency offered by fundamental BJT CROs when they are phase locked to an external crystal in the 1 MHz to 300 MHz range. The single loop model when phase locked to an external 100 M z(PN:-158dBc/Hz@1KHz) crystal provides exceptionally low phase noise,typically-126dBc/Hz at 1 KHz offset at 9GHz.
  In addition, two reference options are available.The first option offers an integrated, high stability internal crystaloscillator in the 100 MHz range in a slim line package.
The second option offers a dual loop design, also in a slim line package. This internal crystal source is phase locked to an external frequency standard between 1 and 300 MHz using digital synthesis techniques and allows the output frequency to be phase locked to an integer or fractional multiple of the reference frequency used.
