DC2035A

Demonstration circuit 2035A features LTC®5551, which is a 300MHz to 3.5GHz ultra high dynamic range down converting mixer. Demo circuit 2035A is optimized for RF input frequency range 1.1GHz to 2.7GHz. IF output port is optimized for frequency range 116MHz to 250MHz. RF input can be matched with few external component for a wide range of frequencies. IF output port can be matched externally up to 500MHz. A typical application with low side LO injection provides the best performance for RF input frequency range 1.1GHz to 2.7GHz. LTC5551 is optimized for 3.3V operation. A low power mode is available and is activated by pulling the ISEL pin high. This reduces the power consumption by 1/3, however reduces the IIP3 to approximately 29dBm.

• VCC supply voltage of 2.5 to 3.6V, VCC supply current of 204mA (EN = high, with LO signal applied)
• Shutdown current (EN = Low) of <lt/>100µA
• Operating temperature range from -40°C to 105°C
