DC2668A

DEMO MANUAL DC2668A LTC5552 3GHz to 20GHz Microwave Mixer with Wideband DC to 6GHz IF DESCRIPTION ABSOLUTE MAXIMUM INPUTS Demonstration circuit 2668A is optimized for evaluation Supply Voltage (V ) ...............................................4.0V CC of the LTC 5552 passive double-balanced mixer. Its RF Enable Input Voltage (EN) ................. 0.3V to V +0.3V CC port is broadband matched from 3GHz to 20GHz, and the LO Input Power (1GHz to 20GHz) .........................10dBm internal LO amplifier, requiring only a 0dBm drive level, RF Power (3GHz to 20GHz) ..................................20dBm is broadband matched to 50 from 1GHz to 20GHz with RF DC Voltage ........................................................ 0.1V + 10dB Return Loss. The differential IF output is usable IF /IF Power (LF to 6GHz) ..................................20dBm + from DC to 6GHz. The LTC5552 can be used for upcon- IF /IF DC Voltage ..................................................0.3V verting and downconverting applications. Operating Temperature Range (T ) ........ 40C to 105C C Junction Temperature (T ) .................................... 150C J Design files for this circuit board are available at Storage Temperature Range .................. 65C to 150C DEMO MANUAL DC2668A PROPER TEST SETUPS Figure 2.
