Evaluate: MAX3541/MAX3542
Note:
Indicate that you are using the MAX3541/MAX3542 when contacting these component suppliers.
Quick Start
Required Equipment
•
•
One power supply capable of supplying at least
500mA at +3.3V
One dual-output power supply capable of supply-
ing up to 3V at least 5mA (to apply gain control
voltages)
One RF signal generator capable of delivering at
least 0dBm of output power at frequency.
(HP 8482A or equivalent)
One RF spectrum analyzer capable of covering the
operating frequency range of the device.
A PC (486DX33 or better) with Windows
®
95/98,
2000, NT 4.0, XP or later operating system, 64MB
of memory, and an available parallel port
One 25-pin parallel cable
50Ω SMA cables
(Optional) One multichannel digital oscilloscope
(Optional) A network analyzer to measure return loss
(Optional) An ammeter to measure supply current
Connections and Setup
This section provides a step-by-step guide to testing
the basic functionality of the EV kits in UHF mode.
Caution: Do not turn on DC power or RF signal gen-
erators until all connections are completed.
1)
Verify that the JP1 and JP6 shunts are removed,
the JP2 shunt is installed, and JP11 and JP12 have
shunts across pins 1-2.
With its output disabled, set the DC power supply
to +3.3V. Connect the power supply to the V
CC
(through an ammeter if desired) and GND termi-
nals on the EV kits. If available, set the current limit
to 500mA.
With its output disabled, set both outputs of the
dual-output DC power-supply voltages to +3V.
Connect one of the outputs to the TP1 connector
and the other output to the IF_AGC connector.
With its output disabled, set the RF signal genera-
tor to a 50.5MHz frequency and a -80dBm power
level. Connect the output of the RF signal genera-
tor to the SMA connector labeled RFIN on the eval-
uation board.
Connect a 25-pin parallel cable between the PC’s
parallel port and the MAX3541/MAX3542 evalua-
tion board.
Turn on the +3.3V V
CC
power supply, followed by
the +3V dual-output gain-control power supply.
The supply current from the +3.3V V
CC
supply
should read approximately 230mA. Be sure to
adjust the power supply to account for any voltage
drop across the ammeter.

7)
Install and run the MAX3541/MAX3542 control
software. Software is available for download at
www.maxim-ic.com/evkitssoftware.
Load the default register settings from the control
software by clicking Edit: Load Defaults.
Connect the SMA connector labeled IF_OUT on
the evaluation board to a spectrum analyzer or to
an oscilloscope.
Layout Considerations
The MAX3541/MAX3542 EV kits serve as a guide for
PCB layout. Keep RF signal lines as short as possible
to minimize losses and radiation. Use controlled imped-
ance on all high-frequency traces. The exposed pad
must be soldered evenly to the board’s ground plane
for proper operation. Use abundant vias beneath the
exposed pad for maximum heat dissipation. Use abun-
dant ground vias between RF traces to minimize unde-
sired coupling.
To minimize coupling between different sections of the
IC, the ideal power-supply layout is a star configuration,
which has a large decoupling capacitor at the central
V
CC
node. The V
CC
traces branch out from this node,
with each trace going to separate V
CC
pins of the
MAX3541/MAX3542. Each V
CC
pin must have a bypass
capacitor with low impedance to ground at the frequen-
cy of interest. Do not share ground vias among multiple
connections to the PCB ground plane.
8)
9)
10) Enable the RF signal generator’s output.
11) Set the center frequency to the IF frequency set on
the control software. Check the output.
Gain Adjustment Calculations
Add an additional 6dB to the voltage gain to account
for the 2:1 transformer on the output. Add another
3.96dB to the voltage gain to account for the minimum
loss pad (R10 and R11) on the input. When measuring
noise figure, account for 5.7dB power loss of the mini-
mum loss pad.
A 36MHz IF anti-aliasing filter is provided on the EV kits
(C9, C12, C21, C25, C28, C29, C31, C35, L3, L9, L10,
and L11). Anti-aliasing filter requirements vary depend-
ing on applications; users should consult their demodu-
lator vendors for more specific information.
