ADAR1000ACCZN

ADAR1000 is a 4-channel, X and Ku frequency band, beam forming core chip for phased arrays. This device operates in half duplex between receive and transmit modes. In receive mode, input signals pass through four receive channels and are combined and output at the common RF-IO pin. In transmit mode, the RF-IO input signal is split and passes through the four transmit channels. A simple 4-wire serial port interface (SPI) controls all of the on-chip registers. In addition, two address pins allow SPI control of upto four devices on the same serial lines. Dedicated transmit and receive load pins also provide synchronization of all device chips in the same array, and a single pin controls fast switching between the transmit and receive modes. It is fabricated in a silicon-germanium, bipolar CMOS (BiCMOS) process. It is used in application such as phased array radar, satellite communications systems etc.
