DC1983A

Demonstration circuit 1983A showcases the LTC®5510 wideband high linearity active mixer for both upconverting and downconverting applications. Its input port is optimized for 30MHz to 3GHz, and its output port is optimized for 1.2GHz to 2.1GHz. The LO input can be either high side or low side. The LTC5510 is a high linearity active mixer optimized for applications requiring very wide input bandwidth, low distortion and low LO leakage. The IC includes a double balanced active mixer with input buffer and a high speed LO amplifier. The mixer can be used for both up- and down-conversion and requires only 0dBm of LO power to achieve excellent distortion and noise performance. The LTC5510 is optimized for 5V but can also be used with a 3.3V supply with reduced performance. The shutdown function allows the part to be disabled for further power saving.

• LO input frequency range from 5 to 6000MHz
• LO input power range from -6 to 6dBm
• Supply voltage range from 4.5 to 5.3V (5V supply, R1 = 4.75Kohm (default configuration))
• Supply current of 99.6mA (5V supply, R1 = 4.75Kohm (default configuration))
• Total supply current during shutdown is 1.3mA (EN = low)
• Turn-on time of 0.6µs (EN: low to high) and turn-off time of 0.6µs (EN: high to low)
