DESCRIPTION EN Chip Enable REFEN Reference Enable MODIN BPSK Modulation Input OOKIN OOK Modulation Input /7 D0/D Digital Synthesizer Programming Input /7 /7 VCO+/ VCO- VCO Output REFOUT REF Output 9 D Digital Synthesizer Programming Input 9 DIV Digital Synthesizer Programming Input 9 N.C. Not Connected Adjustments and Control Operation Modes The EV kits support four modes of operation: SHUTDOWN mode EN = REFEN = low. (Shunt pins and of JU, JU). SYNTH mode EN = REFEN = high, OOKIN = low. (Shunt pins and of JU, JU; shunt pins and of JU). TRANSMIT mode EN = REFEN = OOKIN = high. (Shunt pins and of JU, JU, JU). REFERENCE only mode REFEN = high, EN = low. (Shunt pins and of JU. Shunt pins and of JU). See Table for jumper selection. Modulations The IC supports various modulation modes: BPSK is obtained through the MODIN pin (JU). OOK is obtained digitally with the OOKIN pin (JU). ASK is obtained through the pin. FM is imposed on the VCO or the reference. Synthesizer Programming (MAX900/MAX90/MAX90) The three pins D0, D, D (JU, JU7, and JU9) are used as digital entries to program the synthesizer division ratios (MAX900). For MAX90/MAX90, pin DIV (JU9) is used to select the division ratio of or. Refer to the MAX900 MAX90 data sheet for corresponding division ratios. Modulation Filter and Power Management The RLPF input controls the modulation filter center frequency. Pins PWRSET and are analog inputs Evaluate: MAX900 MAX90 7

8 MAX900 MAX90 Evaluation Kits Evaluate: MAX900 MAX90 used to control the power of the transmitter. Changing the values of the resistors R RLPF and R PWRSET vary the modulation filter characteristics and output power level, respectively. Refer to the MAX900 MAX90 data sheet for details. Output Power Adjustment The MAX900 MAX90 EV kits are tuned for specific output powers. For example, the MAX900 EV kit is tuned for dbm at a.v supply voltage. If other output power levels are desired, the user must modify some EV kit components. This section, intended as a guide only, provides instructions for tuning the EV kits at different power levels. To achieve a different output power, modify R PWRSET (R8) first. This resistor sets the bias current, which also controls efficiency and output power. To decrease output power, increase the value of R8. For more information, refer to the MAX900 MAX90 data sheet. The output-matching network also must be changed to appropriate output power levels. For lower power levels, increase C and C capacitor values. To maintain the same LC filter corner frequency, change L, L, C, and C accordingly. To achieve optimum performance, all component values must be tuned in the lab. Use the EV kit schematics as a guideline. 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 MAX900 MAX90. Keep traces carrying RF signals as short as possible to minimize radiation and insertion loss. Use impedance control on all RF signal traces. The node on the PC board should have decoupling capacitors to the closest ground. Refer to the Layout section of the MAX900 MAX90 data sheet for more information. 8
