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 -80 dBc and harmonics held to -25 dBc. The frequency stability is ±3 ppm with an internal reference of 100 MHz. The phase noise is as follows: -34 dBc/Hz at 1 Hz, -65 dBc/Hz at 10 Hz, -85 dBc at 100 Hz, -108 dBc/Hz at 1 kHz, -115 dBc/Hz at 10 kHz, -120 dBc/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".
