DC2668A

Demonstration circuit 2668A is optimized for evaluation of the LTC®5552 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 50 ohm from 1GHz to 20GHz with 10dB Return Loss. The differential IF output is usable from DC to 6GHz. The LTC5552 can be used for upconverting and downconverting applications.

• Supply voltage (VCC) of 4V (maximum)
• LO input power (1GHz to 20GHz) of 10dBm
• RF power (3GHz to 20GHz) of 20dBm
• RF DC voltage of ±0.1V
• IF+/IF– power (LF to 6GHz) of 20dBm IF+/IF– DC voltage of ±0.3V
• Operating temperature range from -40°C to 105°C
