power separate design
Hello guy:
Do you know how to design diffence Attenuators level for power separate?
one path Attenuator level is 6dB,
one path Attenuator level is 10dB,
BR,:D
Hello guy:
I can't use PI-attenuator circuit in this design.
Maybe can't design diffence Attenuators level...
8051 ice
Hi guy:
How to generator the hex file to 8051 chipset for keil mon-51 ICE simulator(winbond W78E516B)?
1.need add eeprom in circuit for simulator hex file?
I need find out this fail issue.
Thanks!!:D
cdma desense measurement
:cry:
We use QUALCOMM MSM6025 to design cdma Phone.
I have a big problem for RADIATE SENSITIVITY only
-97 dBm in all channel(desense).
How to improve this problem ?
I try remove rf tx/rx chip but radiate sensitivity is -97dBm.

Dear guy :
I use cdma chip is Qualcomm MSM6025 .
Do you have any recommend for RX sensitivity problem ?
I can't reduce 1.228MHz multiple power level.:cry:
Thanks your help !!
I have a cdma design question in air measurement.
AIR RX sensitivity == -96 dB request need above -104 dB.
I've found some noise frequency in rx band(-70 dBm)
Noise frequency is spread rate 1.228MHz's multiple .
How to reduce this noise power ? :cry:
help me !! thanks you help .
