    Hi, I built a 12.48GHz oscillator based on a ADF41513 and a HMC529 VCO. The loop filter was dimensioned using ADIsimPLL. The PLL is in integer-N mode. When measuring the phase noise of the resulting setup, I get a very close fit for low frequencies...

    We use the ADL5303 (single 5 V, buffer ~2.4×) to measure average optical power of a pulsed laser via an externally-biased InGaAs APD (not using VPDB). PRF 250 kHz down to 250 Hz min at ~1% duty; need to resolve average photocurrent down to a few nA. ...
