The LTC5549 is a general purpose passive doublebalanced mixer that can be used for upconversion or downconversion. The RF port is designed for the 2GHz to 14GHz band and the IF port is optimized for 500MHz to 6GHz operation. An integrated LO buffer amplifier supports LO frequencies from 1GHz to 12GHz, requiring only 0dBm LO power. The LTC5549 delivers high IIP3 and input P1dB with low power consumption.

An internal LO frequency doubler can be enabled by a CMOS-compatible digital control pin, allowing operation with a lower, one-half LO input frequency. This allows the mixer’s LO port to be used with existing synthesizers, such as the LTC6946 and LTC6948 family.

The LTC5549’s high level of integration minimizes the total solution cost, board space and system level variation with its 2mm × 3mm package size.

Product Detail

Demonstration circuit 2310A is optimized for evaluation of the LTC5549 passive double-balanced mixer with integrated LO frequency doubler. Its RF port is matched to 50Ω from 2GHz to 13.6GHz with 9dB return loss, and the LO port is matched to 50Ω from 1GHz to 12GHz with 10dB return loss. The IF output is matched to 50Ω from 700MHz to 6GHz with 10dB return loss. The LTC5549 can be used for upconverting and downconverting applications.
