DC1304B-B

DC1304B-B demonstration circuit features the LTC6603 dual, matched, lowpass filter programable 20KHz to 2MHz. A fully differential, dual, 5MHz LPF at the input provides anti-aliasing to a LTC6603 clock-tunable switched-capacitor filter IC. The outputs of the clock-tunable filter are filtered by an LC LPF to attenuate LTC6603 output images.

• Baseband signal chain subsystem for I and Q signal signals
• Board output is a dual fully differential LPF and ADC driver
• Dual differential signal chain from I/P to O/P is matched for min I and Q passband gain, phase error
• 14-pin connector connects DC1304B to Linduino board, DC2026C for programable frequency, gain control
