4. e Two power supplies capable of up to 1A at 2 65V to 3 3V An optional ammeter for measuring the supply current e SMA cables Connections and Setup This section provides a step by step guide to operating the EV kits and testing the devices function Do not turn on the DC power or RF signal generators until all connections are made 1 Connect a DC supply set to 2 775V through an ammeter if desired to the VCC and GND on the EV kit Do not turn on the supply 2 Connect one RF signal generator to the LNA_IN MAXIM MAX2371 MAX2373 Evaluation Kits SMA connector Do not turn on the generator s out put Set the generator for proper output frequency and power level 3 Connect the spectrum analyzer to LNA_OUT Set the spectrum analyzer to a center frequency of 150MHz 2371 9OOMHz 2373 4 Connect the jumpers to set the desired mode of operation Enable Disable High Low Attenuation High Low Current 5 Connect DC supply set to 1 3875 Vcc 2 for maximum gain to AGC Do not turn on the supply 6 Turn on the DC supplies 7 Activate the RF generator s output Refer to the Electrical Characteristics Table in the data sheet for specifications in different operation modes 8 Another method for determining gain is by using a network analyzer optional This has the advantage of displaying gain versus a swept frequency band in addition to displaying input return loss Refer to
5. the network analyzer manufacturer s user manual for setup details Layout Issues A good PC board is an essential part of an RF circuit design The EV kit PC board can serve as a guide for laying out a board using the 2371 2373 Keep traces carrying RF signals as short as possible to mini mize radiation and insertion loss Use impedance con trol on all RF signal traces VCC nodes on the PC board should have decoupling capacitors to the closest ground Refer to the Layout section of the MAX2371 MAX2373 data sheet for more information MAXIM 3 EZLECXVW FLZECXVWN Evaluate MAX2371 MAX2373 MAX2371 MAX2373 Evaluation Kits SMA_EDGE_62 02 15pF 1 019 OOnF Pa li I 56nH MAXIA MAX2371 Figure 1 MAX2371 EV Kit Schematic _ 05 T 1500pF R2 7500 6 sMA_EDGE_62 2 6 8pF 1 MAXIM MAX2371 MAX2373 Evaluation Kits SMA_EDGE_62 MAXIM MAX2373 14 100pF R5 1 5kQ 15 SMA_EDGE_62 1 py 1 6 2 Figure 2 MAX2373 EV Kit Schematic MAXIM 5 EZLETXVNW LZEZXVIN Evaluate MAX2371 MAX2373 MAX2371 MAX2373 Evaluation Kits MAX2371 3 25 LOW FREQUENCY e 1710 le UB SERIAL FADE N THe usa 0 02 2371 3 EVKIT HIGH FREQUENCY 01 02
