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 MAX2206, use a CW input from the signal generator to the RF input. For the MAX2207 MAX2207, use a TDMA input. For the MAX2205/MAX2208 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 MAX2206) or 2mA (MAX2205/MAX2207/MAX2208 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/ MAX2206/ MAX2207/MAX2208 MAX2207/MAX2208, or +0.25V for the MAX2205 MAX2205. 2 _ MAX2205 MAX2205­MAX2208 MAX2208 Evaluation Kits Evaluate: MAX2205 MAX2205­MAX2208 MAX2208 VCC JU1 R1 10k 5% C1 47pF SMA R3 200 R4 200 R5 200 VCC A1 R2 680 R6 200 B1 RFIN/SHDN GND U1 MAX2205 MAX2205 VCC OUT A2 C2 27pF B2 C4 N/I VCC J1 J3 C3 22µF J2 Figure 1.
