DEMO MANUAL DC2461A LTC5548 2GHz to 14GHz Microwave Mixer with Low IF Frequency Description Absolute M A Mu M rA Demonstration circuit 2461A is optimized for evaluation Supply Voltage (EN) ....................................................4V of the LTC 5548 passive double-balanced mixer with Enable Input Voltage (EN) ................0.3V to V + 0.3V integrated LO frequency doubler. Its RF port is matched CC LO Input Power (1GHz to 12GHz) .........................10dBm to 50 from 2GHz to 13.6GHz with 9dB return loss, and LO Input DC Voltage ............................................... 0.1V the LO port is matched to 50 from 1GHz to 12GHz with RF Input Power (2GHz to 14GHz) .........................20dBm 10dB return loss. The differential IF port is usable from RF Input DC Voltage ............................................... 0.1V DC to 6GHz. The LTC5548 can be used for upconverting IF Input Power (LF to 6GHz) .................................20dBm and downconverting applications. IF Input DC Voltage ................................................ 0.1V The internal LO doubler can be enabled to allow operation Operating Temperature Range (T ) ........ 40C to 105C C with a lower frequency LO input signal such as that from Junction Temperature (T ) .................................... 150C J the LTC6945/LTC6946 or LTC6947/LTC6948 family of Storage Temperature Range .................. 65C to 150C frequency synthesizers.
