Connections and Setup
This section provides a step-by-step guide to testing
the basic functionality of the EV kit. As a general pre-
caution to prevent damaging the outputs by driving
high-VSWR loads, do not turn on DC power or RF
signal generators until all connections are made.
This procedure is specific to operation in the U.S. PCS
band (reverse channel: 1850MHz to 1910MHz), low-
side injected LO for a 200MHz IF. Choose the test fre-
quency based on the particular system’s frequency
plan, and adjust the following procedure accordingly.
See Figure 1 for the mixer test setup diagram:
1) Calibrate the power meter for 1700MHz. For safety
margin, use a power sensor rated to at least
+20dBm, or use padding to protect the power head
as necessary.

NOTE: U1 HAS AN EXPOSED
PADDLE CONDUCTOR THAT
REQUIRES IT TO BE SOLDER
ATTACHED TO A GROUNDED PAD
ON THE CIRCUIT BOARD TO
ENSURE A PROPER
ELECTRICAL/THERMAL DESIGN.
2) Connect 3dB pads to the DUT ends of each of the
two RF signal generators ’ SMA cables. This
padding improves VSWR and reduces the errors
due to mismatch.
3) Use the power meter to set the RF signal generators
according to the following:
? RF signal source: -5dBm into DUT at
1900MHz (this will be about -2dBm before
the 3dB pad).
? LO1 signal source: 0dBm into DUT at
1700MHz (this will be about 3dBm before the
3dB pad).
? LO2 signal source: 0dBm into DUT at
Quick Start
The MAX9994 EV kit is fully assembled and factory test-
ed. Follow the instructions in the Connections and
Setup section for proper device evaluation.
Test Equipment Required
This section lists the recommended test equipment to
verify the operation of the MAX9994. It is intended as a
guide only, and substitutions may be possible:
? One DC supply capable of delivering +5.0V and
300mA
? Two RF signal generators capable of delivering
10dBm of output power in the 1GHz to 3GHz fre-
quency range (i.e., HP 8648)
? One RF spectrum analyzer with a minimum 100kHz
to 3GHz frequency range (HP 8561E)
1701MHz (this will be about 3dBm before the
3dB pad).
4) Disable the signal generator outputs.
5) Connect the RF source (with pad) to RFIN.
6) Connect the LO1 and LO2 signal sources to the EV
kits LO1 and LO2 inputs, respectively.
7) Measure loss in 3dB pad and cable that will be con-
nected to IFOUT. Losses are frequency dependent,
so test this at 200MHz (the IF frequency). Use this
loss as an offset in all output power/gain calcula-
tions.
8) Connect this 3dB pad to the EV kit’s IFOUT connec-
tor and connect a cable from the pad to the spec-
trum analyzer.
9) Set DC supply to +5.0V, and set a current limit of
2
