Layout
For the MAX2385/MAX2386, keep RF signal lines as
short as possible to minimize losses and radiation.
Always use controlled-impedance lines on all high-fre-
quency inputs and outputs and use low-inductance
connections to ground on all GND pins. At the mixer
outputs, keep the differential lines together and of the
same length to ensure signal balance.
For the best gain and noise performance, use high-Q
(greater than 40) components for the LNA input match-
ing circuit.
For the power supplies, a star topology works well to
isolate different sections of the device. Each V
CC
node
has its own path to a central V
CC
; place decoupling
capacitors that provide low impedance at the RF fre-
quency of interest close to all V
CC
connections. The
central V
CC
should have a large decoupling capacitor
as well. (Use the MAX2385/MAX2386 EV kit as an
example.)
UCSP Reliability
The UCSP represents a unique package that greatly
reduces board space compared to other packages.
UCSP reliability is integrally linked to the user
’
s assem-
bly methods, circuit board material, and usage environ-
ment. Operating Life and Moisture Resistance remain
uncompromised as they are primarily determined by
the wafer-fabrication process. Mechanical stress per-
formance is a greater consideration for a UCSP. UCSP
solder joint contact integrity must be considered since
the package is attached through direct solder contact
to the user
’
s PC board. Testing done to characterize
the UCSP reliability performance shows that it is capa-
ble of performing reliably through environmental stress-
es. Results of environmental stress tests and additional
usage data and recommendations are detailed in the
UCSP application note, which can be found on Maxim
’
s
website, www.maxim-ic.com.
