? One RF power meter (HP 437B)
? One power sensor (HP 8482A)
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 at an RF frequency
of 910MHz using high-side injected LO for a 160MHz IF.
Choose the test frequency based on the particular
system’s frequency plan, and adjust the following proce-
dure accordingly. See Figure 1 for the mixer test setup
diagram:
1) Calibrate the power meter for 910MHz. For safety

margin, use a power sensor rated to at least
+20dBm, or use padding to protect the power head
as necessary.
2) Connect 3dB pads to the DUT ends of each of the
three 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

? RF signal source: -5dBm into DUT at 910MHz (this
will be approximately -2dBm before the 3dB pad).
? LO1 signal source: 0dBm into DUT at 1070MHz (this
will be approximately 3dBm before the 3dB pad).

Quick Start
The MAX9986A EV kit is fully assembled and factory
tested. 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 MAX9986A. It is intended as
a guide only, and substitutions may be possible:
? One DC supply capable of delivering +5.0V and
300mA
? Three RF signal generators capable of delivering
10dBm of output power in the 700MHz to 1500MHz
frequency range (i.e., HP 8648)
? LO2 signal source: 0dBm into DUT at 1069MHz (this
will be approximately 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
kit’s LO1 and LO2 inputs, respectively.
7) Measure the loss in the 3dB pad and cable that will
be connected to IFOUT. Losses are frequency
dependent, so test this at 160MHz (the IF frequency).
Use this loss as an offset in all output power/gain cal-
culations.
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.
