removed for balanced output operation.
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
LO1_IN is enabled when the LOSEL test point has 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. PWR_UP test point allows PWDN interface to be excercised
using external logic generator. It is permissible to ground the PWDN
pin for nominal operation.
Bias Control. R22 and R23 form a voltage divider to provide a 3V for
logic control, bypassed to ground through C22. VGS0 and VGS1
jumpers provide programmability at pin VGS0 and VGS1. It is
recommeded 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 amplifiers.
