DEMO MANUAL DC1983A LTC5510 1MHz to 6GHz Wideband High Linearity Active Mixer Description Demonstration circuit 1983A showcases the LTC 5510 The LTC5510 is a high linearity active mixer optimized wideband high linearity active mixer for both upconvert- for applications requiring very wide input bandwidth, low ing and downconverting applications. Its input port is distortion, and low LO leakage. The IC includes a double- optimized for 30MHz to 3GHz, and its output port is balanced active mixer with input buffer and a high speed optimized for 1.2GHz to 2.1GHz. The LO input can be LO amplifier. The mixer can be used for both up- and either high side or low side. down-conversion and requires only 0dBm of LO power to achieve excellent distortion and noise performance. The Another demonstration circuit, the DC1984A, is designed LTC5510 is optimized for 5V but can also be used with for evaluating the LTC5510 at the lower output frequency a 3.3V supply with reduced performance. The shutdown range of 10MHz to 1.3GHz. function allows the part to be disabled for further power DEMO BOARD INPUT RANGE LO RANGE OUTPUT RANGE saving.
