MAX2208EVKIT

19-2468; Rev 1; 5/02 MAX2205–MAX2208 Evaluation Kits The MAX2205–MAX2208 evaluation kits (EV kits) simplify the evaluation of the MAX2205–MAX2208 RF power detectors. They enable testing of all functions, with no additional support circuitry. The RF input utilizes a 50Ω SMA connector for convenient connection to test equipment. Features ♦ +2.7V to +5V Single-Supply Operation ♦ 50Ω SMA Connector on RF Input ♦ Fully Assembled and Tested Ordering Information MAX2205 Component List DESIGNATION QTY C1 1 C2 DESCRIPTION PART TEMP RANGE IC PACKAGE MAX2205EVKIT -40°C to +85°C 2 × 2 UCSP MAX2206EVKIT -40°C to +85°C 2 × 2 UCSP MAX2207EVKIT -40°C to +85°C 2 × 2 UCSP MAX2208EVKIT -40°C to +85°C 2 × 2 UCSP MAX2206/MAX2207/MAX2208 Component List DESIGNATION QTY DESCRIPTION 47pF ±5% ceramic capacitor (0402) Murata GRP1555CIH470J C1 1 47pF ±5% ceramic capacitor (0402) Murata GRP1555CIH470J 1 27pF ±5% ceramic capacitor (0402) Murata GRP1555CIH270J C2 1 27pF ±5% ceramic capacitor (0402) Murata GRP1555CIH270J C3 1 22µF electrolytic capacitor, B case size AVX TAJB226K010 C3 1 22µF capacitor, electrolytic, B case size AVX TAJB226K010 C4 1 Not installed C4 1 Not installed SMA 1 SMA connector, edge mount, 0.031in EFJohnson 142-0701-881 SMA 1 SMA connector, edge mount, 0.031in EFJohnson 142-0701-881 J1, J2 2 2-pin headers, 0.1in centers J1, J2 2 12-pin headers, 0.1in centers 1-pin header J3 1 1-pin header J3 1 JU1 1 3-pin header, 0.1in center JU1 1 3-pin header, 0.1in center R1 1 10kΩ ±5% resistor (0402) R1 1 240Ω ±5% resistor (0402) R2 1 0Ω ±5% resistor (0402) (MAX2207/MAX2208), 10Ω ±5% resistor (MAX2206) U1 1 MAX2206EBS (MAX2206EVKIT) MAX2207EBS (MAX2207EVKIT) MAX2208EBS (MAX2208EVKIT) R2 1 680Ω ±5% resistor (0402) R3–R6 4 200Ω ±5% resistors (0402) U1 1 MAX2205EBS ________________________________________________________________ Maxim Integrated Products For pricing, delivery, and ordering information, please contact Maxim/Dallas Direct! at 1-888-629-4642, or visit Maxim’s website at www.maxim-ic.com. 1 Evaluate: MAX2205–MAX2208 General Description Evaluate: MAX2205–MAX2208 MAX2205–MAX2208 Evaluation Kits Quick Start The MAX2205–MAX2208 EV kits are fully assembled and factory tested. Follow the instructions in the Connections and Setup section for proper device setup. 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: 1) Set the SHDN jumper (JU1) on the EV kit to ON. This enables the device. 2) Connect a DC supply set to +2.85V (through a DMM, if desired) to the VCC and GND terminals on the EV kit. If available, set the current limit to 10mA. Do not turn on the supply. 3) Connect the output (J3) to a DMM to measure output voltage. 4) Set the signal generator output to +15dBm, f = 800MHz. For the MAX2206, use a CW input from the signal generator to the RF input. For the MAX2207, use a TDMA input. For the MAX2205/MAX2208, use a CDMA input. Using the power meter, determine the actual power output of the signal generator. Use this value to determine proper operation of the part. Test Equipment Required EQUIPMENT DESCRIPTION Signal Generator with Digital Modulation Capabilities Capable of delivering continuous wave (CW), CDMA, and TDMA signals with +15dBm output power Power Meter To accurately measure the power into the RF input Power Supply Capable of up to 10mA at +2.7V to +6V Digital Multimeters (DMMs) To measure output voltage and supply and output current 5) Connect the signal generator to the SMA connector. Do not turn on the signal generator. 6) Turn on the DC supply; the supply current should read approximately 3.5mA (MAX2206) or 2mA (MAX2205/MAX2207/MAX2208), depending on the part being tested. 7) Activate the signal generator. The output voltage should read approximately +1.8V for the MAX2206/ MAX2207/MAX2208, or +0.25V for the MAX2205. 2 _______________________________________________________________________________________ MAX2205–MAX2208 Evaluation Kits Evaluate: MAX2205–MAX2208 VCC JU1 R1 10kΩ 5% C1 47pF SMA R3 200Ω R4 200Ω R5 200Ω VCC A1 R2 680Ω R6 200Ω B1 RFIN/SHDN GND U1 MAX2205 VCC OUT A2 C2 27pF B2 C4 N/I VCC J1 J3 C3 22µF J2 Figure 1.
