EVALUATION BOARD
An evaluation board is available for the AD8344. The evaluation
board is configured for single-ended signaling at the IF output
port via a balun transformer. The schematic for the evaluation
board is presented in Figure 48.

Supply Decoupling
.
Jumpers or power supply decoupling resistors and filter capacitors.
R3, R4
R6, C11
Jumpers in Single-Ended IF Output Circuit.
R
BIAS
resistor that sets the bias current for the mixer core.
The capacitor provides ac bypass for R6.
Jumper for pull down of the PWDN pin.
Jumper.
RF Input AC Coupling
.
Provides dc block for RF input.
RF Common AC Coupling
. Provides dc block for RF input common connection.
LO Input AC Coupling
.
Provides dc block for the LO input.
LO Common AC Coupling
.
Provides dc block for LO input common connection.
Power Down
.
The part is on when the PWDN is connected to ground via SW1.
The part is disabled when PWDN is connected to the positive supply (V
S
) via SW1.
IF Output Balun Transformer
. Converts differential, high impedance IF output
to single-ended. When loaded with 50 , this balun presents a 200 load to the
mixers collectors. The center tap of the primary is used to supply the bias voltage
(V
S
) to the IF output pins.
IF Output Interface
—IFOP, IFOM. These positions can be used to modify the
impedance presented to the IF outputs.
