DS50002175A-page 12 MCP6421 EMIRR EVALUATION BOARD USER'S GUIDE Chapter 2. Installation and Operation 2.1 INTRODUCTION This chapter shows how to set up the MCP6421EMIRR Evaluation Board. Topics discussed in this chapter include: * Required Tools * MCP6421 EMIRR Evaluation Board Setup * MCP6421 EMIRR Evaluation Board Operation 2.2 REQUIRED TOOLS The following tools are required for testing the functionality of the board: * Lab power supply * High-frequency function generator * Lab measurement equipment (e.g., network analyzer) 2.3 MCP6421 EMIRR EVALUATION BOARD SETUP The MCP6421 EMIRR Evaluation Board uses a single op amp in buffer configuration with RC snubbers as terminations. Figure 2-1 shows the circuit diagram for the board. VDD stage VIN J1 SMA 50_Ohm 1 2 VCAL stage 50 Ohm TX line C2 3 4 R1 R2 DUT U1 MCP6421T-E/LTY SC-70-5 5 R6 1 2 C1 VOUT J3 50 Ohm TX line BNC 50 Ohm 1 2 R7 C5 R8 C6 VSS stage FIGURE 2-1: MCP6421 EMIRR Evaluation Board Circuit Diagram. 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 50 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. 2013 Microchip Technology Inc. DS50000000A-page 13 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. FIGURE 2-2: MCP6421 EMIRR Evaluation Board Top View. 2.3.1 Top Level Amplifier Circuit Diagram 2.3.1.1 POWER SUPPLY BLOCK The op amp is biased by a 50 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 = 49.9, C7 = C9 = C12 = 100 pF, C8 = C10 = 10 uF, C11 = 100 nF and L1 = L2 = 470 ferrite.

DS50000000A-page 14 MCP6421 EMIRR Evaluation Board User's Guide 2.3.1.2 INPUT STAGE The input section consists of a 50 transmission line to match the output impedance of the signal generator and a capacitor to couple AC signal and two parallel resistors that give 50 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 = 100, C2 = 10 nF). J1 SMA 50 Ohm 1 2 50 Ohm TX Line C2 VIN R1 FIGURE 2-4: R2 Input Stage Block. 2.3.1.3 OUTPUT STAGE The output section consists of a 50 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 k, R8 = 49.9, C5 = 100 nF, C6 = 10 nF). R6 R7 50 Ohm TX Line VOUT C5 R8 J3 BNC 50 Ohm 1 2 C6 FIGURE 2-5: DS50000000A-page 15 Output Stage Block. 2013 Microchip Technology Inc. Installation and Operation 2.3.1.4 CALIBRATION STAGE The calibration stage consists of a 50 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 = 49.9 and R3 = R4 = 10 k). R6 R7 50 Ohm TX Line VOUT C5 R8 J3 BNC 50 Ohm 1 2 C6 FIGURE 2-6: Circuit Diagram for Calibration Stage. 2.3.1.5 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. 2.4.1.2.1 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.
