Function
I Channel Baseband Interface. Resistors R7 and R9 may be installed to
accommodate a baseband source that requires a specific terminating
impedance. Capacitors C15 and C19 are bypass capacitors. For single-ended
baseband drive, the Potentiometer R11 can be used to provide a bias level to
the unused input (install either W3 or W4).
Q Channel Baseband Interface. See the I Channel Baseband Interface section.
Baseband Low-Pass Filtering. By adding capacitor C11 between QFLP and
QFLM, and capacitor C12 between IFLP and IFLM, the 3 dB low-pass corner
frequency of the baseband interface can be reduced from 230 MHz (nominal)
as given by the equation in the Evaluation Board section.
Output Interface. The 1:1 balun transformer, T1, converts the 50 Ω differential
output to 50 Ω single-ended. C17 and C18 are dc blocks. L3 and L4 provide dc
bias for the output.
I and Q Channel RF Input Interface. The single-ended impedance to the
ADL5390 RF inputs is 200 Ω. Shunt terminations R2 and R22 of 66.5 Ω bring the
impedances to 50 Ω. C2 and C5 are dc blocks. C1 and C6 are used to ac-couple
the unused side of the differential inputs to common.
Power Supply Decoupling.
Output Disable Interface. The output stage of the ADL5390 is disabled by
applying a high voltage to the DSOP pin by moving SW1 to Position B. The
output stage is enabled moving SW1 to Position A. The output disable
function can also be exercised by applying an external high or low voltage to
the DSOP SMA connector with SW1 in Position A.
