DC2566A, Demonstration Circuit is optimized for evaluation of the LTC5553 passive double-balanced mixer. Its RF port is broadband matched from 3 to 20GHz, and the internal LO amplifier, requiring only a 0dBm drive level, is broadband matched to 50-Ohm from 1 to 20GHz with 10dB Return Loss. The single-ended IF output is broadband matched from 500MHz to 9GHz. The LTC5553 can be used for up-converting and down-converting applications
