MAX2366 Evaluation Kit
General Description
The MAX2366 evaluation kit (EV kit) simplifies testing of
the MAX2366/MAX2367/MAX2368. The EV kit provides
50Ω SMA connectors for all RF inputs and outputs. A
varactor-based tank circuit is provided for the on-chip
voltage-controlled oscillator (VCO) and phase locked
with an on-chip PLL. I/Q baseband inputs come with
standard BNC connectors.
The EV kit allows evaluation of the MAX2366/MAX2367/
MAX2368s’ I/Q modulator, IF VGA, RF upconverter,
dual-band IF VCOs, dual synthesizer, 3-wire program-
ming interface, and power-management features.

Note:
Please indicate that you are using the MAX2366 when
contacting these component suppliers.
Quick Start
The MAX2366 EV kit is fully assembled and factory test-
ed. Follow the instructions in the
Connections and
Setup
section.
Test Equipment Required
This section lists the recommended test equipment to
verify the operation of the MAX2366. It is intended as a
guide only, and substitutions may be possible.
• One TCXO (Temperature-Components Crystal
Oscillator) at 19.68MHz for the PLL reference frequency
• An RF spectrum analyzer with optional digital modu-
lation personality (Rohde & Schwarz FSEA30 or
equivalent)
• A power supply that can provide 250mA at +3.3V
• A power supply that can provide 50mA at +5V
• An additional voltage source for control of VGA functions
• I/Q arbitrary waveform generator or CDMA generator
(Agilent E4433B or equivalent)
• PC (486DX33 or better) with Win95
®
/98
®
, Win2000
®
,
WinNT
®
4.0 or later operating system and an avail-
able parallel port
• INTF2300 interface board (supplied with EV kit)
Figure 8.
Note:
Pin 1 of the interface cable corre-
sponds to the red wire. Pin 1 is designated in
silkscreen on each of the PC boards.
3) Connect a +3.0V power supply to VBAT. The
INTF2300 board derives its power from the MAX2366
EV kit.
4) Connect a +5.0V power supply to the header labeled
“+5V”.
5) Connect the TCXO to the REF port.
6) Connect a CDMA baseband signal generator to the
I and Q ports using BNC connectors. Set the modu-
lation to reverse-channel CDMA
7) Install and run Maxim CDMA control software.
Software is also available on the web at
www.maxim-ic.com.
On the IC selection form, click
on the MAX236X control button. Select P4. Click on
register views.
8) With the MAX236X control screen active, set the reg-
isters according to Table 1.
9) Click on the Send Data button for each of the con-
trol registers located at the right of the screen.
There are six registers that need to be downloaded
to the IC. The Lock indicator on the screen (and on
the EV board) should be red, indicating lock.
10) Apply 2.5V to GC via JU4.
11) Connect RFL to the spectrum analyzer. Configure
the spectrum analyzer to measure ACPR for
reverse-channel CDMA. Set the center frequency to
836MHz with a +10dBm reference level.
12) The output power should be about +7dBm after
accounting for cable and connector loss. The ACPR
at ±885kHz offset should be -54dBc, and the ACPR
at ±1.98MHz offset should be -65dBc.
Connections and Setup
This section provides step-by-step instructions for get-
ting the EV kit up and running in cellular and PCS
CDMA modes.
Cellular CDMA Mode
Perform the following steps to evaluate the MAX2366 in
the cellular CDMA mode:
1) Verify shunts JU1, JU2, and JU6–JU10 are in place.
2) Connect the INTF2300 interface cable as shown in

RHF0 PCS CDMA Mode
Perform the following steps to evaluate the MAX2366 in
the PCS CDMA mode:
1) Remove shunt JU2 and place shunt in JU3. This
removes V
CC
for the cellular VCO and applies V
CC
to the PCS VCO.
2) With the MAX236X control screen active, set the
registers according to Table 1.
3) Click on the Send Data buttons for each of the con-
trol registers located at the right of the screen.
There are six registers that need to be downloaded
to the IC. The lock indicator on the screen should
be red, indicating lock.
4) Apply a 2.6V to VGC via JU4.
5) Connect the RFH0 port to the spectrum analyzer.
Configure the spectrum analyzer to measure ACPR
for reverse-channel CDMA. Set the center frequen-
cy to 1880.01MHz with a +10dBm reference level.
6) The output power should be about +6dBm after
accounting for cable and connector loss. The ACPR
at ±1.25MHz offset should be -54dBc.

Programming Interface
The programming interface is provided by the
INTF2300 interface board. The interface board buffers
and level shifts logic levels from the PC to the MAX2366
EV kit (refer to the INTF2300 documentation). These
logic signals control the logic pins as well as the serial
interface.
Adjustments and Control
VGA Adjust
Apply a voltage from 0.5V to 2.6V to header “VGC” to
adjust the IF and RF VGA of the MAX2366/MAX2367/
MAX2368. The VGC voltage is filtered on the EV kit to
minimize undesired amplitude modulation.
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
0Ω resistors; and remove R38, C12, C24, L10, D1, and D2.
Interface Control
The interface port is designed to use a 20-pin ribbon
cable (Figure 1); 10 pins are signal lines, and the other
10 pins are digital grounds. Pin 1 of the interface cable
is red. Pin 1 is also designated in silk screen on each of
the PC boards.
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.
Detailed Description
The following section covers the EV kit’s circuit blocks
in detail (refer to the MAX2366/MAX2367/MAX2368
data sheet for additional information).
LOH
LOH is the high-band RF LO input port. To use this port
with an external signal source, disconnect the PCS
VCO by removing C39 and placing it at location C66.
I/Q Inputs
The single-ended I/Q signals are converted to differen-
tial by operational amplifiers on the EV kit. The op amps
also provide DC bias to the I/Q input pins of the
MAX2366/MAX2367/MAX2368. The EV kits are set up to
provide 415mVp-p differential to the IC when used with
a 50Ω source that delivers 1Vp-p into 50Ω. For other
I/Q levels, replace R9 and R18 with appropriate resistor
values according to Table 2.
LOL
LOL is the low-band RF LO input port. 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 a PCS PA driver output. Refer to Table 6 in the
MAX2366/MAX2367/MAX2368 data sheet for the mode
description.
