RFFM4202 biasing instructions to the eval board: 802.11b/g/n transmit: 1. connect the fem to a signal generator at the input and a spectrum analyzer at the output. set the pin at signal generator is at -20dbm. 2. bias v cc to 5.0v first with v reg =0.0v. if available, enable the current limiting function of the power supply to 1100ma. 3. refer to switch operational truth table to set the control lines at the proper levels for wifi tx. it is recommended to maint ain at least 2.85v on vtx during tx mode. a lower vtx voltage will en able the switch in tx mode, but 2.85v is needed to ensure that the switch stays in tx mode during high power peaks. us ing a vtx voltage less than 2.85v in tx mode could result in abnormal operation or device damage. 4. turn on v reg to 2.85v (typ). 5. on v reg (of evaluation board), a regulated supply is recommended . be extremely careful not to exceed 3.0v on the v reg pin or the part may exceed device current limits. 6. turn on p down to 2.85v (typ). p down pin can be tied to v reg supply. note: it is important to adjust the v cc voltage source so that +5v is measured at the board; and the +2.85v of v reg is measured at the board. th e high collector currents will drop the collector voltage significantly if long lead s are used. adjust the bias voltage to compensate. 7. turn on rf of signal generator and gradually increase power level to the rated power. caution: if the input signal exceeds the maximum rated power, the RFFM4202 evaluation board can be permanently damaged. 8. to turn off fem, turn off rf power of signal generator; then p down , v reg and v cc . 802.11b/g/n receive ? to receive wifi set the switch control lines per the truth table. free datasheet http://

RFFM4202 tx production and system calibration recommendation: it is highly recommended to follow the dc biasing step an d rf power settings in the production calibration or test: 1. connect the rf cables of input and output then connect to the proper equipment. 2. apply v cc , then v reg as per the data sheet recommendations. 3. set fem in tx mode by the truth table. 4. apply p down = high. 5. set rf input to the desired frequency and initial rf input powe r at -20dbm. this will insure the power amplifier is in a line ar state and not over driven. 6. sweep rf from low to high output power and take measurements at the rated output power. 7. insure that the output power at turn on doesn't saturate the power amplifier. the recommended output power should be about 10db to 20db below the nominal input power. start calibrating from low to high power in reasonable steps until the rated power is reached then take the measurements. caution: if the input signal exc eeds the maximum rated input power specifications, the RFFM4202 co uld be permanently damaged. free datasheet http://
