Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

The power supply voltage needs to be within the allowed range for the op amp. The
MCP6421 op amp supports a maximum of 5.5V power supply. Power supply is ensured
by a 50Ω transmission line and by LC filters to minimize noise injection (see
Figure 2-3).
All component labels on the board are consistent with those on the schematic. The op
amp uses the SC70-5 package.

Installation and Operation
The BNC and SMA connectors for the power supply, ground, input signals, output
signals, and voltage calibration allow the lab equipment to be connected to the board.
The MCP6421 EMIRR Evaluation Board top view is shown in Figure 2-2.

POWER SUPPLY BLOCK
The op amp is biased by a 50Ω transmission line, RC snubbers and LC low-pass filter
to reject high-frequency power supply noise. Figure 2-3 shows the circuit diagram for
the power supply, where R9 = R10 = 49.9Ω, C7 = C9 = C12 = 100 pF,
C8 = C10 = 10 uF, C11 = 100 nF and L1 = L2 = 470Ω ferrite.

INPUT STAGE
The input section consists of a 50Ω transmission line to match the output impedance
of the signal generator and a capacitor to couple AC signal and two parallel resistors
that give 50Ω input impedance at the op amp input. The AC coupled input signal
minimizes changes in the DC input offset. Figure 2-4 shows the circuit diagram for the
input section (R1 = R2 = 100Ω, C2 = 10 nF).

OUTPUT STAGE
The output section consists of a 50Ω transmission line to match the input of the network
analyzer and to minimize the inductance, antenna effects and disturbance effects, and
a double pole RC low-pass filter to minimize DC loading and crosstalk. Figure 2-5
shows the circuit diagram of the output section (R6 = R7 = 10 kΩ, R8 = 49.9Ω,
C5 = 100 nF, C6 = 10 nF).

CALIBRATION STAGE
The calibration stage consists of a 50Ω transmission line and a double pole RC
low-pass filter, and is the same as the output stage. The calibration stage provides a
DC output from VIN, after the coupling capacitor, measuring the op amp offset without
input signal. Measure the 2nd harmonic distortion (HD2) for the AC source to offset
conversion versus frequency and power without populating the op amp, and correct the
DC output from VOUT using both calibration measurements. Figure 2-6 shows the
circuit diagram of the calibration stage (C4 = 10 nF, C3 = 100 nF, R5 = 49.9Ω and
R3 = R4 = 10 kΩ).

DEVICE UNDER TEST (DUT) STAGE
The DUT block consists of an op amp in buffer configuration with one capacitor on the
output. Figure 2-7 shows the circuit diagram of the DUT buffer block. The output
capacitor (C1 = 22 pF) and parasitic layout capacitance present an output capacitive
load of about 30 pF (standard condition for the data sheet specs).

BOARD VALIDATION
This board was built, and its responses were measured. All resistors have 1%
tolerance. The capacitors have 5% and 10% tolerance.

Measurements Results
In Bench Measurement:
• VDD = 5.5V
• VCAL
• The amplifier’s gain is 1 V/V
Measure the EMIRR versus frequency. The level of the input signal is 100 mVpp.
Measure the EMIRR as function of the level of the input signal. The frequency of the
input signal needs to have the following values: 400 MHz, 900 MHz, 1800 MHz,
2400 MHz.
The EMIRR definition is:
