DC2566A - LTC5553 | 3GHz to 20GHz Passive Bidirectional Mixer

Demonstration circuit DC2566A is optimized for evaluation of the LTC®5553 passive double-balanced mixer. Its RF port is broadband matched from 3GHz to 20GHz, and the internal LO amplifier, requiring only a 0dBm drive level, is broadband matched to 50Ω from 1GHz to 20GHz with 10dB Return Loss. The single-ended IF output is broadband matched from 500MHz to 9GHz. The LTC5553 can be used for upconverting and downconverting applications.
