DEMO MANUAL DC2153A LTC6430-15 300MHz to 1700MHz Differential ADC Driver/IF/RF Amplifier Description Demonstration circuit 2153A features the LTC6430-15 has 100 differential input and output impedances, so differential ADC/IF Amplifier. The LTC6430-15 has a power the demo circuit uses transformers to convert to 50 gain of 15.2dB and is part of the LTC6430-YY amplifier single-ended so that it can be easily evaluated with most series. RF test equipment. The DC2153A demo board supports the LTC6430-YY ampli- Design files for this circuit board are available at fier family. The DC2153A demo board is optimized for the S11 , S12 , S22 , (dB) DEMO MANUAL DC2153A p s Table 1.

Two-tone test conditions: Output power level = 2dBm/tone, tone spacing = 1MHz. 2. Single-tone test conditions: Output power level = 6dBm. 3. Degraded performance results are due to imbalance from the balun transformers. 4.
