HI Albbg,
thanks.. but the tolerance varies depending on the RL. for example for 10dB RL as per above calculation VSWR tolerance is +/-0.5188 for +/-3dB RL tolerance, and same for 6dB RL the VSWR tolerances is +/- 1.8741. is there any relation ship between RL and VSWR for the tolerance.
Hi
i am looking for Wimax standard for CPE can any one guide me which standards i need to look in for latest release , there are lot versio in IEEE pls help me to select latest one.

Hi
1. How to determine exact knee voltage of FET( ex of MRF8S9100H)?
2. what is IDQ and P_Avg. datasheet say's following information
"typical GSM EDGE Performance: VDD = 28 Volts, IDQ = 700 mA, Pout = 45 Watts Avg."
is IDS_avg =pout_avg/vdd =1.607 A, then how to determine IDS_peak...
thanks.. ok, if i maintain same the impedance what transceiver required by adjusting the RF trace Width and matching components, then i can choose different stackup?
hi,
will there be any changes in internal impedance or performance of RF transceiver chip if i use different stack up other than the reference design?. i am aware that different stack up will affects impedance of the RF traces/tracks but what about the transceiver chip alone?.
regards
hi all
Apart from Risk is there will be any performance affect for transceiver.. as per vfone app-note(attachment) i planned to go with capacitive power supply with RC filter at output and use 2FSK or GMSK modulation,
will i have to go for particular modulation scheme for this kind the...
hi tony
1. ok, what would be main reason?
2. planned to use 2 FSK or GFSK or MSK
i can't go for transformer due to space constraints .. project customer specification.

Hi all,
for one of my RF project, I have to provide 5 volts supply to RF transceiver module witch operates in 868MHz, due to space constraints i have go for resistor to step down the 230 volts power supply to 5 volts(without using transformer) and convert to DC 5/3.3 volts by using...
Re: Transmitted Power
Hi,
---- this value is for harmonics/spurious not for main peak power level, as per FCC for fundamental power at 2.4G is 50mV/m at 3m = 0.75 mW (-1.25 dBm EIRP).
refer attachment for further details.

Hi,
its very easy to measure in network analyzer, or if you have S parameter of chip u can easily find the impedance of chip by plotting S(S22) parameter on smith chart.

Hi,
This Oscilloscope for ur project is very less use, but u can use this to measure DC values and also u can make use to measure RF power by means of external RF detector. build ur own RF detector by using simple Schottky diode and connect this ckt to o/p of ur amplifier to measure DC...
