  • RF Source provides true sinewave output with low phase noise.
    Designed using surface acoustic wave resonator technology, 2 GHz Model CRFS75-2000 features -134 dBc/Hz phase noise at 10 KHz offset and noise floor of -164 dBc/Hz. Source has no sub-harmonics; second harmonic is -20 dBc typical, and frequency accuracy is rated at ±150 ppm. With 5 V input voltage, device generates true sinewave with +5 dBm minimum output power. Housed in 0.75 x 0.75 in. SMT ...
