Each kit enables testing of the device’s RF performance and requires no additional support circuitry. The EV kit input and output use SMA connectors and baluns (for single-ended-to-differential conversions) to facilitate the connection to RF test equipment. Each EV kit is assembled with either the MAX2045, MAX2046, or MAX2047 and incorporates all matching components optimized for the corresponding band of frequency operation. Evaluate: MAX2045/MAX2046/MAX2047 MAX2045/MAX2046/MAX2047 Evaluation Kits MAX2046 Component List DESIGNATION QTY 3.9pF ±0.1pF, 50V C0G ceramic capacitor (0402) Murata GRP1555C1H3R9B C1–C16 16 47pF ±5%, 50V C0G ceramic capacitors (0402) Murata GRP1555C1H470J 2 220pF ±10%, 50V X7R ceramic capacitors (0402) Murata GRP155R71H221K C17 1 0.01µF ±10%, 25V X7R ceramic capacitor (0402) Murata GRP155R71E103K 12 22pF ±5%, 50V C0G ceramic capacitors (0402) Murata GRP1555C1H220J J1, J2 2 PC board edge-mount SMA RF connectors (flat-tab launch) EFJohnson 142-0741-856 1 6.2pF ±0.25pF, 50V C0G ceramic capacitor (0402) Murata GRP1555C1H6R2C J3 1 Header 10 x 2, 0.100in spacing Molex 10-89-1201 L1 1 15nH ±5% chip inductor (0402) Toko LL1005-FH15NJ L2 1 39nH ±5% chip inductor (0402) Toko LL1005-FH39NJ R1 1 280Ω ±1% resistor (0402) Any R2, R4, R6 0 Not installed R3, R5 2 0Ω resistors (0402) Any T1 1 1:1 balun (50:50) Murata LDB20C500A900 T2 1 4:1 balun (200:50) Murata LDB20C201A900 U1 1 MAX2047ETJ-T (32-pin QFN) DESIGNATION QTY C1 1 C2, C3 C4–C13, C15, C16 C14 MAX2047 Component List DESCRIPTION C17 1 0.01µF ±10%, 25V X7R ceramic capacitor (0402) Murata GRP155R71E103K J1, J2 2 PC board edge-mount SMA RF connectors (flat-tab launch) EFJohnson 142-0741-856 J3 1 Header 10 x 2, 0.100in spacing Molex 10-89-1201 L1 1 1.5pF ±0.1pF, 50V C0G ceramic capacitor (0402) Murata GRP1555C1H1R5B L2 1 12nH ±5% chip inductor (0402) Toko LL1005-FH12NJ R1 1 280Ω ±1% resistor (0402) Any R2, R4, R6 0 Not installed R3, R5 2 0Ω resistors (0402) Any T1 1 1:1 balun (50:50) Murata LDB15C500A1900 T2 1 4:1 balun (200:50) Murata LDB15C201A1900 U1 1 MAX2046ETJ-T (32-pin QFN) DESCRIPTION Quick Start The MAX2045/MAX2046/MAX2047 EV kits are fully assembled and factory tested. Follow the instructions in the Connections and Setup section for proper device evaluation. The EV kits come configured for single-ended, voltage-control operation. For differential voltage- or current-mode operation, see the Detailed Description section. Test Equipment Required Table 1 lists the required test equipment to verify the MAX2045/MAX2046/MAX2047 operation. It is intended as a guide only, and some substitutions are possible. Connections and Setup This section provides a step-by-step guide to operating the EV kits and testing the devices’ functions. Do not turn on DC power or RF signal generators until all connections are made. 2 _______________________________________________________________________________________ MAX2045/MAX2046/MAX2047 Evaluation Kits EQUIPMENT QTY DESCRIPTION Power supply 1 Capable of delivering up to 250mA at 4.75V to 5.25V Power supplies 2 Capable of swinging from 0 to +5.5V Current sources (optional) 2 Capable of delivering 5mA of current Low-noise RF signal generators 2 HP 8648B or equivalent Network analyzer 1 HP 8753ES or equivalent Ammeter/voltmeters 2 — 50Ω SMA cables 2 — Testing the Supply Current 1) If available, set the current limit of the power supply to 250mA. Do not turn on the supply. Connect the DC supply set to 5V, through an ammeter, to the VCC and GND terminals on the EV kit. Use a voltmeter to verify that the voltage is at VCC = 5V. 2) Turn on the DC supply; the supply current should read approximately 160mA. Testing the Gain (Single-Ended Voltage Mode) 1) Connect a DC supply set to +3.2V to the VI1 and VQ1 terminals (Figure 1). 2) Using a calibrated network analyzer, connect port 1 to the RF_IN terminal (SMA J1) and port 2 to the RF_OUT terminal (SMA J2). 3) Configure the network analyzer to measure S21. The analyzer should read approximately 7dB gain at fIN = 2140MHz (MAX2045), 7.4dB gain at f IN = 1900MHz (MAX2046), and 8.4dB gain at f IN = 915MHz (MAX2047). 4) Changing the DC supply on the VI1 and VQ1 terminals changes the magnitude of the gain. To adjust the phase, use separate DC supplies on the VI1 and VQ1 terminals. Testing the Gain (Current Mode) 1) Configure the evaluation kits for current mode (see the Detailed Description section). 2) Connect a current source set to 4mA to the II1 and IQ1 terminals. Leave II2, IQ2, and all voltage-control pins open (Figure 1). 3) Using a calibrated network analyzer, connect port 1 to the RF_IN terminal (SMA J1) and port 2 to the RF_OUT terminal (SMA J2). 4) Configure the network analyzer to measure S21. The analyzer should read approximately 6.2dB gain at fIN = 2140MHz (MAX2045), 6.6dB gain at f IN = 1900MHz (MAX2046), and 8.1dB gain at f IN = 915MHz (MAX2047). 5) Changing the current source value changes the magnitude of the gain. To adjust the phase, use separate current sources on the II1 and IQ1 terminals. Detailed Description The EV kits come with all necessary components for easy testing. For each kit, make sure all ground pins on the 20-lead header are connected to ground. The REFOUT voltage can be monitored from pins 17 and 18 on the 20-lead header by installing a 0Ω resistor for R6. To operate the device in differential voltage-control mode, remove R5 and R3, and install 0Ω resistors for R2 and R4. Figure 1 shows the connections on the 20pin header corresponding to the voltage- and currentcontrol inputs. Using this configuration, an external DC source can also be applied to VI2 and VQ2 for singleended operation using an external regulated voltage. For current-mode operation, leave the VI and VQ (header pins 1, 2, 5, and 6) open, and remove R3 and R5. Bias Resistor The bias resistor value (280Ω) was optimized during characterization at the factory. This value should not be adjusted. If the 280Ω (±1%) resistor is not readily available, substitute a standard 280Ω (±5%) resistor. On-Chip Reference Voltage An on-chip, 2.5V reference voltage is provided for single-ended control mode. REFOUT is connected, through R3 and R5, to VI2 and VQ2 to provide a stable reference voltage. The equivalent output resistance of the REFOUT pin is approximately 80Ω. REFOUT is capable of sourcing 1mA of current with
