Product Overview

DC1774A-A is a demo circuit for LTC6430-15 high linearity differential IF amplifier/ADC driver. The DC1774A-A is optimized for a frequency range of 100MHz to 300MHz and utilizes a minimum of passive external components to configure the amplifier for this application. Because the LTC6430-15 has 100ohm differential input and output impedance, the demo circuit uses transformers to convert the impedance to 50ohm single ended allowing easy evaluation with commercially available RF test equipment. Demo Circuit 1774A-A is a highly linear fixed gain amplifier. The LTC6430-15 is internally matched to a 100ohm differential source and load impedance from 20MHz to 1300MHz. The frequency range of the circuit is limited by the balun transformers. Hence, this demo board works best with a frequency range from 100MHz to 300MHz.
