DEMO MANUAL DC2310A LTC5549 2GHz to 14GHz Passive Bidirectional Mixer Description aB L Maxi Mu M r Demonstration circuit 2310A is optimized for evaluation of the LTC 5549 passive double-balanced mixer with Supply Voltage (V ) ..................................................4V CC integrated LO frequency doubler. Its RF port is matched Enable Input Voltage (EN) ................0.3V to V + 0.3V CC to 50 from 2GHz to 13.6GHz with 9dB return loss, and LO Input Power (1GHz to 12GHz) ....................... +10dBm the LO port is matched to 50 from 1GHz to 12GHz with LO Input DC Voltage ............................................... 0.1V 10dB return loss. The IF output is matched to 50 from RF Input Power (2GHz to 14GHz) .......................+20dBm 700MHz to 6GHz with 10dB return loss. The LTC5549 can RF Input DC Voltage ............................................... 0.1V be used for upconverting and downconverting applications. IF Input Power (0.5GHz to 6GHz) .......................+20dBm IF Input DC Voltage ................................................ 0.1V The internal LO doubler can be enabled to allow operation Operating Temperature Range (T ) ........ 40C to 105C with a lower frequency LO input signal such as that from C Junction Temperature (T ) .................................... 150C the LTC6945/LTC6946 or LTC6947/LTC6948 family of J Storage Temperature Range .................. 65C to 150C frequency synthesizers.
