8V97003 Wideband 18GHz RF and Microwave Synthesizer

August 30, 2020 by Renesas Electronics

The 8V97003 is a high-performance wideband microwave synthesizer/phase lock loop (PLL) that generates output frequencies up to 18GHz from an integrated Voltage Controlled Oscillator (VCO) offering an octave of frequency tuning range.

The device offers a high-performance 32-bit fractional feedback divider and an output divider to allow users to fully benefit from the wideband characteristics of the VCO. The device's figure of merit (FOM) of -236dBc/Hz and the excellent VCO performance allow for very low phase noise and RMS phase jitter. The 8V97003 offers a very low output-to-output phase skew drift of <10° across all operating conditions and frequencies, reducing radio path recalibration occurrences in beamforming applications, such as 5G radio card massive MIMO systems.

The output drivers have programmable output power settings and can deliver high single-ended output power up of +12dBm at 8GHz, and +4dBm at 18GHz, when using inductively loaded output terminations (double termination). When the outputs are resistively loaded, the output drivers can deliver a single-ended output power of +9.5dBm at 8GHz, and up to -2.5dBm at 12GHz. The output power can be further increased when using differential outputs and measuring the output power differentially.

The 8V97003 relies on a single 3.3V power supply and offers low noise integrated LDOs for excellent power supply noise immunity.
