The board provides SMA connectors for the RF and LO port
inputs, the demodulated I and Q outputs, the manual gain con-
trol (MGC) input, the PLL input, and the power-up input. In
addition, the IF output is also available at an SMA connector;
AD607
this may be connected to the PLL input for carrier recovery to
realize synchronous AM and FM detection via the I and Q de-
modulators, respectively. Table III lists the AD607 Evaluation
Board’s I/O Connectors and their functions.
