Description
Power Supply and Ground Vector Pins.
Power Supply Decoupling. Shorts or power supply decoupling resistors.
The capacitors provide the required dc coupling up to 6 GHz.
Device Enable. When connected to V
Adjust Pin. The resistor value here sets the bias voltage at this pin and optimizes
third-order distortion.
AC Coupling Capacitors. These capacitors provide the required ac coupling
from 400 MHz to 4 GHz.
Single-Ended Baseband Output Path. This is the default configuration of the
evaluation board. R13x to R18x are populated for appropriate balun interface.
R2x to R5x are not populated. Baseband outputs are taken from QHI and IHI. The
user can reconfigure the board to use full differential baseband outputs. R2x to R5x
provide a means to bypass the 9:1 TCM9-1 transformer to allow for differential base-
band outputs. Access the differential baseband signals by populating R2x to R5x
with 0 Ω and not populating R13x to R18x. This way the transformer does not need
to be removed. The baseband outputs are taken from the SMAs of QHI, QLO, IHI,
and ILO. R6x and R7x are provisions for applying a specific differential load across
the baseband outputs
IF Output Interface. TCM9-1 converts a differential high impedance IF output to
a single-ended output. When loaded with 50 Ω, this balun presents a 450 Ω load
to the device. The center tap can be decoupled through a capacitor to ground.
Decoupling Capacitors. C15x and C16x are the decoupling capacitors used to reject
noise on the center tap of the TCM9-1.
LO Input Interface. A 1:1 RF balun that converts the single-ended RF input to
differential signal is used.
RF Input Interface. A 1:1 RF balun that converts the single-ended RF input to
differential signal is used.
