Dielectric Resonator Oscillator: PIA-12D8G-CD-1

April 17, 2017

  

PMI Model No. PIA-12D8G-CD-1 is a Phase Locked, Dielectric Resonator Oscillator with Internal Reference having an output frequency of 12.8 GHz.  This model provides a minimum output of +13 dBm with all spurs held to -80dBc and harmonics held to -25 dBc.  The frequency stability is ±3 ppm with an internal reference of 100MHz.  The phase noise is as follows: -34 dBc/Hz at 1 Hz, -65 dBc/Hz at 10 Hz, -85 dBc at 100 Hz, -10 8dBc/Hz at 1 kHz, -115 dBc/Hz at 10 kHz, -12 0dBc/Hz at 100 kHz, and -140 dBc/Hz at 1 MHz offsets. 

 

The oscillator requires +15 VDC and 300mA.  There is a built in alarm which outputs a TTL signal when phase locked.  The unit measures 2.25" x 2.25" x 0.62".
