Demonstration circuit 2233 is an adaptor board to be used with the LTC2000. It is designed to receive a differential signal from J1 and J2 and output a single-ended signal on J3. This is done with a pair of transformers with a range from 5MHz to 1000MHz. The spacing of J1 and J2 is 0.8". This spacing mates with the analog outputs of the LTC2000 demo board (the DC2085). This board was designed with a 50Ω output impedance to drive a spectrum analyzer, or other 50Ω ports.
