DESCRIPTION

Quick Start

The MAX2150 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 MAX2150. It is intended as a

guide only, and substitutions are possible.

• One RF signal generator capable of delivering

-7dBm of output power in the 10MHz to 50MHz fre-

quency range (HP 8648A or equivalent) for the PLL

reference frequency

• RF spectrum analyzer capable of measuring up to 7GHz

RF signal (Rohde & Schwarz FSEA20 or equivalent)

• RF power meter capable of measuring up to

+10dBm output power (HP 437B or equivalent) with

an RF sensor

• RF network analyzer

• Oscilloscope

• Two power supplies that can provide 250mA at

+5.0V (AG E3631A or equivalent)

• Arbitrary waveform generator (HP E4433B or equivalent)

Connections and Setup

This section provides step-by-step instructions for get-

ting the EV kit up and running in all operation modes.

1) Verify that jumpers are in place.

2) Verify that the interface board is in place.

Note 1:

This IC has an exposed pad. It must be solder

attached to the circuit board to ensure proper function.

Note 2:

Cut center pin to approximately 1/16in long.

3) Set the power supply to +3V and turn it off.

4) Set the adjustable power supply to +1.6V and turn it

off.

5) Connect the ground terminal to GND.

6) Connect the positive +3V terminal to VCC and the

power supply of the interface board.

7) Connect the positive terminal of the adjustable

power supply to pin DCIN on the board.

8) Set the I/Q generator to 330kHz, with an input level

of 1V

P-P

. Leave the I/Q generator output off.

9) Using 2 BNC cables, connect the output of the I/Q

generator to the I/Q input connectors on the

MAX2150 EV kit board.

10) Use an SMA cable to connect the RFOUT to the

input of the spectrum analyzer.

11) Set the spectrum analyzer to view the output.

12) Turn on all power supplies and enable I/Q signal

generator.

13) Measure the supply current level.

14) Observe the RF output frequency as displayed on the

spectrum analyzer. Measure the RF output power.

15) The RF output power should be approximately

-4dBm after accounting for cable and connector loss.

Operation Modes:

1) TX mode

2) SYNTH mode

3) MOD mode

4) Software shutdown mode

5) Hardware shutdown mode

Refer to the MAX2150 data sheet for details.

Adjustments and Control

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 MAX2150. Keep traces

carrying RF signals as short as possible to minimize

radiation and insertion loss. Use impedance control on

all RF signal traces. The VCC node on the PC board

should have decoupling capacitors to the closest

ground. Refer to the

Layout

section of the MAX2150

data sheet for more information.
