2-24GHz RF Rx & Tx Front End for MxFE

The 2-24GHz RF Front End is a complete RF receiver and transmitter front end designed to meet the specifications of typical wideband instrumentation and electronic warfare (EW) systems. The latest generation of high performance RF/microwave and mixed signal components available from ADI are used to reduce system SWaP (size, weight, and power) and architectural complexity.

The full system block diagram is shown below, consisting of four functional blocks- the receiver front end, transmitter front end, digitizer, and LO generation.



Specifications

The receiver and transmitter specifications, shown in the table below, are fairly typical of many wideband instrumentation and EW systems in operation today. The signal chain is capable of 1GHz instantaneous bandwidth (IBW) in both receive and transmit modes across the full 2-24GHz operating range.

These specs may not be “one-size-fits-all” for every potential use case, but the signal chain architecture and component selection is extremely flexible, allowing for modifications of the individual pieces to meet specific performance or functionality targets. Everything from the digitizer sample rates to the individual RF components and signal chain filtering can be adjusted to facilitate changes in frequency planning or system-level functionality.
