Linear Technology DC2566A Demo Manual

Description
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.
