General
PVG610X System-on-a-chip equipped with embedded cross-polarization interference cancellation (XPIC) technology doubles the wireless capacity over the channel, by transmitting and receiving two orthogonally polarized signals at the same RF carrier frequency.
The PVG610X provides an unparallel level of performance and integration in a single ASIC for Broadband Wireless Transmission systems. Used in applications such as cellular backhaul networks, fixed wireless transmission, and private wireless networks. It is a powerful mixed signal device providing complete processing chain from user data interfaces through a high performance modem to carrier IF frequency. Innovative DSP mitigates analog impairments and allows overall system cost reduction.
