Follow the instructions in the Connections and Setup section for proper device evaluation. Test Equipment Required This section lists the test equipment recommended to verify operation of the EV kits. It is intended as a guide only, and some substitutions are possible. • An RF signal generator capable of delivering at least +10dBm of output power at the operating frequency with CDMA modulation (HP E4433G, or equivalent) • An RF power sensor capable of handling at least +20dBm of output power at the operating frequency (HP 8482A, or equivalent) • A 20dB high-power attenuator • An RF power meter capable of measuring up to +20dBm of output power at the operating frequency (HP EPM-441A, or equivalent) • An RF spectrum analyzer capable of measuring ACPR and covering the MAX2267/MAX2268/MAX2269’s operating frequency range (Rhodes at Schwartz FSEA20, for example) • A power supply capable of up to 1A at +2.7V to +5V • A high-impedance voltmeter for measuring the actual operating voltage • An ammeter for measuring the supply current (optional) • Two 50Ω SMA cables • A network analyzer (HP 8753D, for example) to measure small-signal return loss and gain (optional) 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 the DC power or RF signal generator until all connections are made: 1) Connect a 20dB high-power attenuator to the OUT SMA connector on the EV kit. This will prevent overloading the power sensor and the power meter. 2) Connect a DC supply set to +3.5V (through an ammeter if desired), and connect the voltmeter to the EV kit’s VCC and GND terminals. 3) Connect an RF signal generator to the IN SMA connector. Set the generator for a 906MHz output frequency at a 0dBm power level. 4) Connect the power sensor to the power meter. Calibrate the power sensor for 906MHz. Set the power meter offset to compensate the 20dB attenuator plus any cable loss (between 0.5dB and 2dB) and circuit board losses (approximately 0.1dB). 4 5) Connect a power sensor to the 20dB high-power attenuator. 6) Place the HIGH/LOW jumper (JU1) in the HIGH position and the ON/OFF jumper (JU2) in the ON position. 7) Turn on the DC supply. The supply current should read approximately 90mA to 100mA. 8) Activate the RF generator’s output. Set the RF generator’s output to produce a reading of +27dBm on the power meter. Verify that the voltmeter reads +3.5V. Iteratively adjust the power supply’s output and the RF generator’s output to produce a +3.5V reading on the voltmeter and a reading of 27dBm on the power meter: a) For the MAX2267, the supply current should increase to approximately 490mA. b) For the MAX2268, the supply current should increase to approximately 420mA. c) For the MAX2269, the supply current should increase to approximately 480mA. 9) For the MAX2267/MAX2269 EV kits: a) Adjust the RF generator’s output to -10dBm. Turn off the RF generator’s output. b) Place the HIGH/LOW jumper (JU1) in the LOW position. c) The supply current reading should drop to approximately 34mA. d) Activate the RF generator’s output. e) Adjust the RF generator’s output for a +17dBm power meter reading. Iteratively adjust the power supply’s output and the RF generator’s output to produce a reading of +3.5V on the voltmeter and a +17dBm reading on the power meter. The supply current should increase to approximately 120mA/90mA (MAX2267/MAX2269). _______________________ Layout Issues A good PC board is an essential part of an RF circuit design. The EV kit PC board can serve as a guide for laying out a board using the MAX2267/MAX2268/ MAX2269. Keep traces carrying RF signals as short as possible to minimize radiation and insertion loss due to the PC board. Each VCC node on the PC board should have its own decoupling capacitor. This minimizes supply coupling from one section of the IC to another. Using a star topology for the supply layout, in which each VCC node on the circuit has a separate connection to a central VCC node, can further minimize coupling between sections of the IC. _______________________________________________________________________________________ _______________________________________________________________________________________ VCC R9 0Ω C23 0.1µF OFF ON VCC VCC C30 22pF LOW HIGH JU2 R10 0Ω C22 0.1µF JU1 C26 470pF C9 100pF VCC C7 100pF BIAS1H VCC PWR IN1 5 V CC 4 C3 0.01µF 3 2 1 L2 5.6nH 8 7 U1 MAX2267 C11 4.7pF SMA OUT OUT1 BIAS2L 6 SHDN C5 0.01µF R4 7.5k 1% C8 0.01µF R3 51k C6 100pF C4 100pF R2 26.1k 1% C2 100pF R1 51k C1 5.1pF C12 4.7pF C10 7.5pF OUT1 BIAS1L OUT0 NFP GND VCC BIAS2H IN0 L1 3.3nH 9 10 11 12 13 14 15 16 U2 0Ω R5 24.3k 1% N.C.
