_______________________________________________________________________________________
Quick Start
The MAX2820/MAX2821 EV kits are 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 ver-
ify the operation of the MAX2820/MAX2821. It is intended
as a guide only, and substitutions may be possible.
DC supply capable of delivering +5.0V and 200mA
of continuous current
DC supply capable of delivering -5.0V and 200mA
of continuous current
DC supply capable of delivering +2.7V and 200mA
of continuous current
HP8663A or equivalent low-noise signal source
capable of generating a 22MHz or 44MHz refer-
ence oscillator signal
Two HP8648 or equivalent signal sources capable
of generating 0dBm up to 3GHz
802.11b waveform generator
HP8561E or equivalent RF spectrum analyzer with a
minimum frequency range of 100kHz to 3GHz
TDS3012 or equivalent oscilloscope with 200MHz
bandwidth
IBM PC or compatible with Windows 95/98
,
Windows 2000
, Windows NT
4.0, or later operat-
ing system and an available parallel port
Male-to-male 25-pin parallel cable, straight through
Connections and Setup
This section provides step-by-step instructions for get-
ting the EV kit up and running in all modes:
1) To control the MAX2820/MAX2821 through the 3-wire
interface, connect the male-to-male 25-pin parallel
cable between the PC and EV kit.
2) With the power supply turned off, connect a +2.7V
power supply to the headers labeled VCC (J19) and
VCCO (J10). Connect the power-supply ground to
the header labeled GND (J18).
3) With the power supply turned off, connect a +5V
power supply to the header labeled +5V (J22), and a
-5V power supply to the header labeled -5V (J20).
Connect the power-supply ground to the header
labeled GND (J21).
4) Connect the low-noise signal source to ROSC (J17).
5) Install and run the MAX2820/MAX2821 control software.
6) With the MAX2820/MAX2821 control software active
in the “Settings” screen, use Table 1 to set the oper-
ating mode to Shutdown.
7) Turn on the +5V and -5V power supplies, followed by
the +2.7V power supply.
8) Set the low-noise signal source to 22MHz with an
amplitude of -10dBm. Enable the signal source.
Receive Mode
To evaluate the MAX2820/MAX2821 in receive mode:
1) Connect an RF signal source to RX_RF (J2). Set the
RF frequency to 2437.9MHz with an amplitude of
-40dBm.
2) Connect RX_BBI (J5) to the spectrum analyzer. Set
the spectrum analyzer to span from 100kHz to 5MHz.
3) Place the receive LNA in high-gain mode through the
control software.
