MAX2360 Evaluation Kit
The MAX2360 evaluation kit (EV kit) simplifies testing of
the MAX2360/MAX2362/MAX2364. 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 can be tuned
by a potentiometer or external voltage, or phase locked
with an on-chip PLL. I/Q baseband inputs come standard with BNC connectors.
The EV kit allows evaluation of the MAX2360/MAX2362/
MAX2364s’ variable-gain amplifier (VGA), I/Q IF modulator, IF VGA, RF upconverter, dual-band IF VCOs, dual
synthesizer, 3-wire programming interface, and powermanagement features.
The MAX2360 EV kit also allows evaluation of the singleband MAX2362/MAX2364, as they are subsets of the
MAX2360.

Quick Start
The MAX2360 EV kit is fully assembled and factory tested. 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 MAX2360. It is intended as a
guide only, and substitutions may be possible.
• One RF signal generator capable of delivering
-7dBm of output power in the 10MHz to 50MHz frequency range (HP 8648A or equivalent) for the PLL
reference frequency
• An RF spectrum analyzer with optional CDMA personality (Rohde & Schwarz FSEA20 or equivalent)
• A power supply that can provide 250mA at +3.0V
• Low-noise power supply (HP 6236B or equivalent),
or voltage regulator
• Optionally, an additional voltage source for external
control of VGA functions
• I/Q arbitrary waveform generator or CDMA generator
(HP E4433B or equivalent)
• PC (486DX33 or better) with Win95 ® or Win98 ®
operating system and an available parallel port
• INTF2300 interface board (supplied with EV kit)
Connections and Setup
This section provides step-by-step instructions for getting the EV kit up and running in cellular and PCS
CDMA modes.
Win95 and Win98 are registered trademarks of Microsoft Corp.
Cellular CDMA Mode
Perform the following steps to evaluate the MAX2360 in
the cellular CDMA mode:
1) Verify shunts JU4, JU6–JU10, and JU12 are in
place. Connect the cellular VCO module side of
JU2 to the low-noise power supply or a regulator.
This is to prevent excessive supply pushing, which
degrades the ACPR of narrow-band modulation
such as IS-136, even though the ACPR of CDMAmodulated signals is not affected.
2) Connect the INTF2300 interface cable as shown in
Figure 7. Note: Pin 1 of the interface cable corresponds to the red wire. Pin 1 is designated in
silkscreen on each of the PC boards.
3) Download the serial-interface control software at
www.maxim-ic.com/techsupport/other/htm and
install on a PC with a parallel port.
4) Connect a +2.85V power supply to the VBAT and
VREG terminals. The INTF2300 board derives its
power from the MAX2360 EV kit.
5) Connect a function generator to the REF port, configured for a sine wave with a frequency of
19.68MHz and an amplitude of -13dBm.
6) Connect a CDMA baseband signal generator to the
I and Q ports using a BNC connector. Configure the
output for 200mVRMS. The EV kit includes transformers at the I and Q inputs that do not pass signals below 50kHz. For evaluation of digital mode
with low-frequency content, bypass the transformer
as described in the Detailed Description.
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 MAX2360 control button.
8) With the MAX2360 control screen active, click on the
cellular CDMA preset located at the left of the
screen.
9) Click on the Send Data button for each of the control registers located at the right of the screen.
There are seven registers that need to be downloaded to the IC. The Lock LED on the screen
should be red, indicating lock.
10) Set the VGA control to 2.5VDC by rotating potentiometer R66. Optionally, an external VGA control
voltage may be used by removing jumper JU4 and
applying a DC voltage to header VGC. Current consumption is about 150mA. This includes the RF
VCO and the potentiometers.
11) Connect RFL to the spectrum analyzer. Configure a

spectrum analyzer to measure ACPR for reversechannel 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 -70dBc.
Low-Band PCS CDMA Mode
Perform the following steps to evaluate the MAX2360 in
the PCS CDMA mode:
1) Connect the PCS VCO module side of JU3 to the
low-noise power supply or a regulator.
2) With the MAX2360 control screen active, click on
the PCS Low preset located at the left of the screen.
3) Click on the Send Data buttons for each of the control registers located at the right of the screen.
There are seven registers that need to be downloaded to the IC. The Lock LED on the screen
should be red, indicating lock.
4) Set the VGA control to 2.55VDC by rotating potentiometer R66. Optionally, an external VGA control
voltage may be used by removing jumper JU4 and
applying a DC voltage to header VGC. Current consumption is about 150mA. This includes the RF
VCO and the potentiometer.
5) Connect the RFH1 port to the spectrum analyzer.
Configure a spectrum analyzer to measure ACPR
for reverse-channel CDMA. Set the center frequency to 1880.38 MHz with a +10dBm reference level.
6) The output power should be about 7dBm after
accounting for cable and connector loss. The ACPR
at ±1.25MHz offset should be -54dBc.
Adjustments and Control
VGA Adjust
The MAX2360 EV kit is configured with a 10kΩ trim potentiometer for setting and adjusting the VGA gain. By
removing the two-pin shunt JU4, an external supply can
be used by directly connecting to header VGC. The
VGC voltage is filtered on the EV kit to minimize undesired amplitude modulation.
Optional VCO External Adjust
The MAX2360 EV kit is configured with a 10kΩ trim potentiometer for setting and adjusting the VCO tune voltage. Apply a two-pin shunt to JU1. Stuff a 0Ω resistor
for R33, and remove R38 to break the loop and remove
the charge-pump output. The VCO voltage must be
clean to minimize undesired frequency modulation.
4
Interface Control
The interface port is designed to use a 20-pin ribbon
cable (Figure 8); 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.
IDLE
A logic low on the IDLE pin shuts down everything
except the RF PLL and associated registers.
TXGATE
A logic low on the TXGATE pin shuts down everything
except the RF PLL, IF PLL, IF VCO, serial bus, and registers. This mode is used for gated transmission.
SHDN
A logic low on the SHDN pin powers down the entire
device, including registers and the serial interface.
Detailed Description
The following section covers the EV kit’s circuit blocks
in detail (refer to the MAX2360/MAX2362/MAX2364
data sheet for additional information).
I/Q Inputs
The I/Q ports are high-impedance differential baseband
inputs. They require a DC bias level of 1/2 VCC with
6µA of current drive. For convenience, the MAX2360 EV
kit provides a transformer that provides a single-ended
to differential conversion and provides bias for the I/Q
inputs. The transformer makes it easy to interface with
single-ended test equipment, but due to its low-frequency cutoff of 50kHz, does not allow full evaluation of the
MAX2360. To evaluate the part over its full bandwidth,
use shielded twisted-pair transmission line to connect a
differential signal source to the differential pads provided
on the EV kit. Stuff R10, R12, R15, and R17 with 0Ω resistors and remove R6, R8, R14, and R16 when using the
differential pads.
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 MAX2360
EV kit (refer to the INTF2300 documentation). These
logic signals control the logic pins as well as the
MAX2360 serial interface.
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 disabled by setting the BUF_EN bit
to 0 in the OPCTRL register.

Layout Considerations
The MAX2360 EV kit can serve as a guide for your
board layout. Keep PC board trace lengths as short as
possible to minimize parasitics. Also, keep decoupling
capacitors as close to the IC as possible with a direct
connection to the ground plane.
PC Board Construction
The MAX2360 EV kit PC board uses a 14mil-wide trace
for 50Ω transmission line. The PC board has an 8millayer profile on FR4 with a dielectric of 4.5 and a trace
to coplanar ground-plane spacing of 15mil.
6
INTF2300 SPI Interface Board
The INTF2300 interface board is used to interface
3-wire SPI protocol from a PC’s parallel port to a device
under test. This board will level translate 5V logic from
the PC to VCC of the device under test (typically this will
be 3.3V logic). The INTF2300 also provides buffering
and EMI filtering. Its absolute maximum supply voltage
is 4.6V, limited by the breakdown of the buffer IC. The
recommended operating supply voltage range is +2.7V
to +3.6V. For operations above +3.6V, jumper JU1 may
be removed and an external supply voltage of +3.6V
may be applied between VCC (pin 2) and GND (pin 1)
(Figure 8).
