To design a silicon K band transceiver and sell as an open market integrated circuit. Competitor designs are less integrated and more expensive.
The transceiver is targeted at the parabolic antenna satellite broadband market but a lot of intellectual property is transferable to phased array antenna systems.
Picture shows SITKA evaluation PCB. SITKA is in lower left of picture.
The main challenges were achieving (1) sufficient electrical isolation between transmitter and receiver (2) low receiver Noise Figure. Due to modest overall gain the backend circuitry impacts the receiver NF (3) a low phase noise VCO to maintain lock over wide temperature range.
There are few competing integrated circuits solutions in the market. The integrated circuit offers a low cost RF solution to a broadband terminal.
The product provides a baseband to K band direct up conversion transmitter and K band to L band image reject receiver. The device also integrates low phase noise phase locked loops, RF power detectors and calibration circuitry to optimise receive image rejection and LO leakage.

The radio system engineering, RF design, layout, verification and evaluation are completed.
COMPLETED. Functional silicon has been evaluated.
