Function
Power Supply and Ground Vector Pins.
Power Supply Decoupling. Shorts or power supply decoupling resistors.
These capacitors provide the required decoupling up to 2.7 GHz.
AC Coupling Capacitors. These capacitors provide the required ac coupling from
700 MHz to 2.7 GHz.
Single-Ended Baseband Output Path. This is the default configuration of the evaluation
board. R14 to R16 and R4, R5, and R13 are populated for appropriate balun interface.
R9, R10 and R11, R12 are not populated. Baseband outputs are taken from QHI and IHI.
The user can reconfigure the board to use full differential baseband outputs. R9 to R12
provide a means to bypass the 9:1 TCM9-1 transformer to allow for differential baseband
outputs. Access the differential baseband signals by populating R9 to R12 with 0 Ω and
not populating R4, R5, R13 to R16. This way the transformer does not need to be
removed. The baseband outputs are taken from the SMAs of Q_HI, Q_LO, I_HI, and I_LO.
Input Biasing. Inductance and resistance sets the input biasing of the common
base input stage. The default value is 33 nH.
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. C12 and C13 are the decoupling capacitors used to reject noise
on the center tap of the TCM9-1.
LO Input Interface. The LO is driven differentially. ETC1-1-13 is a 1:1 RF balun that
converts the single-ended RF input to differential signal.
RF Input Interface. ETC1-1-13 is a 1:1 RF balun that converts the single-ended RF input
to differential signal.

BIAS
