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.
