With 1.8-GHz carrier open-loop VCO phase noise of -144.5 dBc/Hz at a 1-MHz offset, the LMX2582 is one of the first PLLs with an integrated VCO to meet the multicarrier wireless GSM communication ...

The ADF4371 synthesizer from Analog Devices offers a wide continuous RF output range of 62 MHz to 32 GHz and an ultra-low normalized phase noise floor (FOM) of -234 dBc/Hz. Consisting of a PLL with ...

Both models have typical phase noise of -142 dBc/Hz at 100 Hz offset and noise floor down to -183 dBc/Hz at 100 kHz offset. These ... These high performance VCO’s can be used in RADAR, ...

A 300 kHz loop bandwidth was used for the phase noise measurements to suppress the VCO noise to clearly view the synthesizer phase noise contribution. Other performance measurements are listed in ...

The performance is achieved by the ADF4377 synthesizer delivering jitter levels below 18fs rms as a consequence of the low normalised in-band phase noise at -239dBc/Hz, -147dBc/Hz normalised 1/f noise ...

Analog Devices is aiming at basestations with a phased-locked loop (PLL) synthesiser with integrated voltage-controlled oscillator (VCO). Called ADF4355, typical phase noise is -144dBc/Hz (1MHz offset ...

I understand what you’re saying. AND, if you were broadcasting a signal on 915 MHz, would you measure the noise on 2.4 GHz? Of course not. You measure the noise at the frequency of the signal.

Texas Instruments has introduced a wideband frequency synthesizer with integrated voltage-controlled oscillator (VCO) that delivers the industry’s lowest phase noise. Key specification and features: ...

Figure 5. Integer-N, ADF4106 with VCO-1901846T. Figure 6. Fractional-N, ADF4153A with VCO-1901846T. The ability to increase PFD frequency and frequency resolution was accompanied by improvements to ...

National Semiconductor Corporation has introduced the LMX2531, a monolithic phase-locked loop and voltage-controlled oscillator (PLL + VCO) integrated circuit with a frequency range of 765 MHz to ...
