Features

? Zero I/F operation in 2.4GHz (2.4-2.5GHz) Low and

5GHz (4.9-6GHz) High Industrial, Scientific, and

Medical (ISM) Bands

– Three independently operating RF sub-systems.

– One dual band 1x2 MIMO transceiver, TRX

– One dual band observation receiver, RO1

antenna operation

? Receiver features

– Direct conversion, low noise and high dynamic

range receive chain

– High speed AGC interface (RSSI detector and RX

gain control) to baseband

– Analog baseband filters (20, 40 and 80 MHz

modulation bandwidth) with on-chip calibration

– Analog differential I/Q interface to baseband IC

? Transmitter features

– Direct conversion with adjustable gain transmit

chain

– Analog baseband filter (20, 40 and 80 MHz

modulation bandwidth) with on-chip calibration

– Analog differential I/Q interface to baseband

? Flexible frequency generation system

– 40 MHz crystal or external oscillator for frequency

reference

– Adjustable crystal load to tune for minimum

frequency error

– 4X multiplied input reference that can be routed to

an output differential pair to be used as a low jitter

160 MHz reference by other devices in the system

– Independent synthesizers for each sub-system driven

by a common reference

? Two interfaces for configuration and bi-directional data

exchanges with the baseband IC

– A low complexity high-speed custom LVDS bus

(LLCP)

– A traditional low-speed I2C bus

? Programmable digital core for transceiver control and

calibration

? Auxiliary ADC support for calibration and external

functions (voltage and temperature measurements)

? 64 pin QFN package
