What I really know is to build a project to simulate a power amplifier in software, ADS, MWO etc.
so can you help to build working file or a similar one, which will give me reference. thanks
I want to use transistor 2sc5753 from NEC to build an 915MHz power amplifier
Vcc=3V
Pout=18 dBm
effeciency > 50%
the datasheet of this transistor had been attached here
Can someone give me an initial design, then I can to align the component
values for final product
Thank you very much!!
thanks for ur reply.
all the test and measurement, including certification standard, i fully understand.
what i am interested, is that I can simulate these parameter in system design.
for example, I can simulate the "intermodulation rejection" of this type of 2-downconverter FM receiver in...
vhf intermodulation marine
How to evaluate the "intermod. rejection" and "blocking/desensitization" in FM super-hereodyne receiver?
anyone give some comments?
marine vhf transceiver block diagram
the attached documents is "service manual" of this 2-way radio, including schematic, PCB layout, part list etc.
it's a good example to let us to discuss the 2-way radio in about 156MHz VHF band
156mhz vhf receiver schematic
please find the attached tech. document of one 2-way radio from Kenwood, model of TK-8150. just for your reference.
Recently i was charging of developing the similar the 2-way radio, I want to get your help here.
any comments and suggestion is appreciated...

Hi,
Could anyone send me the following standard? Thanks much

Hi everyone,
My buyer want to help to build the following jig,which requirement listed as below.
Could somebody give me some suggestion?
Thanks very much
test rig built to do a particular experiment.
The details of the design are:
Two female COAX inputs
One female COAX output
Both inputs...
Dear Bigboss
thanks
your filter seems reach our requirement
q: could you guarantee 470Mhz, 860MHz are within the bandwidth?
Could you give me some ref. design about this UHF filter?
