Function/Notes
Capacitors can be installed for controller mode.
Optional pull-down resistors.
The dynamic range of the AD8364 is directly related to the
magnitude and phase balance of the balun feeding the RF
signal to the part. The evaluation board includes M/A-COM
ETK4-2T soldered to the board and two unsoldered M/A-COM
ETC1.6-4-2-3. The ETK4-2T has good magnitude and phase
balance between 10 MHz and 650 MHz, but slowly degrades
above 650 MHz due to the balun. The M/A-COM ETC1.6-4-2-3
broadband baluns allow limited dynamic range performance
between 500 MHz and 2500 MHz. Better dynamic range can be
achieved by using narrow band baluns with better magnitude
and phase performance.
Supply filtering/decoupling capacitors.
Supply filtering/decoupling capacitors.
VREF filtering/decoupling capacitor.
Optional VLVL filtering/decoupling capacitor.
Output low-pass filter capacitors (CLPA/B).
Output low-pass filter capacitors, which can be activated by
removing jumpers R6 and R15.
Input bias-point decoupling capacitors (DECA/B).
Input bias-point decoupling capacitors (DECA/B).
Stable, low ESR capacitors are mandatory in the RF input area
of the AD8364. This corresponds to capacitors connected to
Pins INH[A, B], INL[A, B], DEC[A, B], and CHP[A, B]. Poor quality
capacitors may result in amplitude and phase mismatch at the
differential inputs, which in turn results in low dynamic range.
Capacitors with poor aging characteristics under temperature
cycling have been shown to accentuate the temperature drift
during operation of the AD8364. Using Samsung CL10 series
multilayer ceramic capacitors (or similar) in the RF area is
suggested.
Input high-pass filter capacitor (CHPA/B).
R17/R19 are usually jumpers and R18/R20 are usually left open.
The pads for R17/R18 or R19/R20 can be used to make voltage
dividers to set the ADJA/B voltages for temperature
compensation at different frequencies.
R12 is usually a jumper and R13 is usually open, but the pads
can also be used to make a voltage divider to adjust the slope of
Channel B.
