Vaunix has recently announced the capability to deliver built-to-spec and custom engineered low phase noise multi-port synthesizers with up to four independently controlled signal sources. The core architecture has been optimized to provide superior phase noise and spurious performance while minimizing component costs and production time. Features include extremely low phase noise, 100 MHz GPSDO compatible reference input, independent phase control, and excellent harmonic rejection. Applications include: LO sources in high data rate communication systems such as 5G, high performance test equipment for RADAR receiver systems, RF/Microwave engineering/production test labs, and wireless automated test equipment (ATE).
