MaXEA 1.0
30V Integrated Envelope Modulator Eval Board
The MaXEA 1.0 is part of the MaXentric Technologies GreenAmp-lite Envelope Tracking product line. The
design represents a major leap forward in RF power amplification for wireless communication, providing a
wideband high efficiency RF power amplifier solution. The MaXEA is an integrated envelope modulator
designed in a high voltage silicon process.

MaXEA 1.0 Evaluation Kit Datasheet
Revised 14 May 2015
Operating Instructions
The MaXEA1-EVAL kit is supplied with a 100Ω resistive test load (MaXLOAD). This test load can be
connected to the MaXEA1-EVAL board for simple testing prior to inserting MaXEA1 into an envelope
tracking system with an RF PA. The following is set of instructions for initial functionality testing of the kit.
MaXentric recommends that the user complete this test to familiarize themselves with the MaXEA1. It
should be noted that although the MaXEA1 is highly efficient, when testing with a resistive load all power
including output power is converted to heat. Thus it is recommended that a small fan be arranged to blow
over the two boards during testing.

MaXEA1 +32V DC
MaXEA1 Ground
In the figure below the various connections on the board are labeled and described. The supply and
output connectors include a push button release mechanism and accept wire gauges 22-18 AWG (20
AWG recommended).

1. Connect the output signal and ground to the load using short wires that are stripped on the ends.
Wires should be kept short < 30 mm to minimize parasitic inductance. The wires can be pushed
directly into the connectors. Gently pushing the release points on top of the connector eases
insertion.
2. Connect cables to the power supply connectors in the same fashion. For ease of testing, cables
with “banana plug” connectors on one end and bare wire on the other can be used.
3. Connect an SMA cable to the input connector. Furthermore a high impedance scope probe can
be attached to the load test points for measurement.
4. The -5V, 20V, GND and 32V DC power supply connectors can now be attached to a supply and
turned on in the following order. -5V, 20V, 32V. If using separate supplies ensure that a common
ground is used.
5. An input signal can now be applied. For this test case use a 1MHz sine wave which has a 2.6V
peak to peak level and 1.7V DC level or offset (i.e. 3V peak and 400mV minimum). Note that the
input impedance of the evaluation board is 1KΩ, thus if using a 50Ω supply the voltage which
appears on the board will be approximately double that of the intended output of the instrument.
6. The output voltage can now be measured as having a 30V peak and 4V minimum.
