PVG310 Features
The PVG 310 is a single chip QAM, transmitter/receiver, PHY solution which integrates all baseband functionality for point-to-point broadband wireless systems. Designed for the microwave (<11GHz) and mm-wave (>11GHz) frequency bands, the PVG 310 supports various data rates with high spectral efficiency while significantly lowering overall system costs.
