RFIC
–
Siklu’s integrated Silicon Germanium (SiGe) transceiver operating at 71-76 GHz.
Modem/Baseband ASIC
– Siklu’s modem/baseband ASIC includes the modem, FEC
engines, and Synchronous Ethernet support.
Network Processor –
The network interface consists of two integrated 100/1000
Ethernet MAC I/F. The block is suitable for both copper and fiber interfaces by using the
external PHY.
The networking engine is the heart of the high speed bridge/router function. The engine
receives packets from both Ethernet interfaces and from the modem. It is responsible
for proper forwarding between these three ports.
Host processor (integrated with the network processor)
–
The general purpose host
processor controls the system, and the antenna alignment system. The processor is
integrated with standard peripherals such as memory controller, communication I/F,
WD, GPIO, and motor controller.
Antenna
– Siklu’s self-designed, innovative antenna is designed for best price-
performance ratio.
