IFLO
The IFLO output port provides an output signal that is
either the IF VCO frequency or the VCO frequency
divided by 2, depending on the setting of the BUF_DIV
control bit. It can be enabled by setting the BUF_EN bit
to 1 in the OPCTRL register.
TANK BYP
The tank bypass port is provided to drive the high-band
tank with an external LO source. The VCO_BYPASS bit
should be set to 1 to enable this port. Replace C25 with
0.01μF AC-coupling capacitor; replace R36 and R70 with
0
resistors; and remove R38, C12, C24, L10, D1, and D2.
REF
REF is the reference frequency input to the RF and IF
PLL. The REF port is AC-coupled. Make sure the refer-
ence signal has low phase noise.
LOH
LOH is the high-band RF LO input port. The EV kit is
shipped with this port disconnected. To use this port
with an external signal source, disconnect the PCS
VCO by removing C39 and placing it at location C66.
LOL
LOL is the low-band RF LO input port. The EV kit is
shipped with this port disconnected. To use this port
with an external signal source, disconnect the cellular
VCO by removing C40 and placing it at location C65.
RFH1
RFH1 is the PCS lower half-band PA driver output.
Refer to Table 9 in the MAX2361/MAX2363/MAX2365
data sheet for the mode description.
RFL
RFL is the cellular band PA driver output. This port is
active in cellular and FM modes. Refer to Table 9 in the
MAX2361/MAX2363/MAX2365 data sheet for the mode
description.
RFH0
RFH0 is the PCS upper half-band PA driver output.
Refer to Table 9 in the MAX2361/MAX2363/MAX2365
data sheet for the mode description.
IFINH and IFOUTH
For cascade evaluation, an on-board filter is connected
between IFOUTH and IFINH. Select these ports by pro-
gramming IF_SEL to 1. IFINH and IFOUTH are not con-
nected to SMA connectors on the EV kit
IFINL and IFOUTL
For cascade evaluation, an on-board filter is connected
between IFOUTL and IFINL. Select these ports by pro-
gramming IF_SEL to 0. For individual IF modulator and
upconverter evaluation, remove R44, R49, R55, R58,
and install R25, R33, R34, and R39 with 0
resistors.
This connects the IFINL_ and IFOUTL_ pins to the IFINL
and IFOUTL SMA connectors. The matching networks
are tuned to 130MHz.
VBAT/VREG
VBAT supplies V
CC
to the PA driver circuitry. This may be
an unregulated battery voltage. The PA drivers are open
collector. Jumpers are provided to enable current mea-
surement to each functional block of the IC (Table 3).
VREG is connected to the output of the U2 regulator on
the EV Kit. Do not connect an external supply voltage to
VREG header.
RBIAS
When resistor R73 is stuffed (typically 10k
), a bias volt-
age may be applied to the RBIAS header to adjust the
PA driver bias current. Internal to the IC, pin 12 is set to
600mV. Output linearity or efficiency may be improved
by adjusting PA driver current.
Layout Considerations
The MAX2361/MAX2363W EV kits can serve as guides
for your board layout. Keep PC board trace lengths as
JUMPER NO.
