Notes:
(1)  Accuracy +/- 2 MHz max.
(2) Typical power level at least 1 dB higher than minimum.  Higher power level available.
(3) Guaranteed phase noise is 5 dB higher than typical.
(4) Wider temperature range available.
(5) +12V nominal,  other voltages customer to specify.
(6) Height dimension of .63" exclude tuning screw height (.25" max), Height to be .75" under 8 GHz.
Unit performances frequently meet or exceed typical level.

Applications: Small size and cost effective, temperature stable with excellent phase noise and low microphonics.  Frequency is field adjustable mechanically and electrically; ideal for commercial communication: Fiber Optics, up/down converter or transceiver LO applications, where low cost, excellent phase noise and frequency stability are optimized to system performance requirements.  Other applications include FMCW doppler radar, and tunable LO where fast and linear frequency adjustments are made by applying tuning voltage.
