Description
Power Supply Decoupling. Nominal supply decoupling consists of
a 10 μF capacitor to ground in parallel with a 10 pF capacitor to
ground positioned as close to the device as possible.
RF Input Interface. The input channels are ac-coupled through C1.
C4 and C5 provide bypassing for the center taps of the RF input baluns.
IF Output Interface. T1 is a 1:1 impedance transformer used to provide
a single-ended IF output interface. Remove R1 for balanced output
operation. C24 and C25 are used to block the dc bias at the IF ports.
LO Interface. C10 and C12 provide ac coupling for the LO1_IN and
LO2_IN local oscillator inputs. LOSEL selects the appropriate LO input
for both mixer cores. R4 provides a pull-down to ensure that LO1_IN is
enabled when the LOSEL test point is logic low. LO2_IN is enabled
when LOSEL is pulled to logic high.
PWDN Interface. R21 pulls the PWDN logic low and enables the device.
The PWR_UP test point allows the PWDN interface to be exercised
using the an external logic generator. Grounding the PWDN pin for
nominal operation is allowed. Using the PWDN pin when supply
voltages exceed 3.3 V is not allowed.
Bias Control. R22 and R23 form a voltage divider to provide 3 V for
logic control, bypassed to ground through C22. VGS0 and VGS1
jumpers provide programmability at the VGS0 and VGS1 pins. It is
recommended to pull these two pins to ground for nominal operation.
R9 sets the bias point for the internal LO buffers. R14 sets the bias point
for the internal IF amplifier.
