Hi. Go to the "GLCD.c" driver file, and change the following parameters:
#define GLCD_LEFT 1 (originally is 0)
#define GLCD_RIGHT 0 (originally is 1)
You should be able to get the correct display!!!
Hello. It is important not to starve your Mixer with LO port, being it in actual operating enviroment (in your PCB or module implementation) or during lab characterisation using VNA. Give it the desired LO, and you will get the right VSWR. The published resturn loss measurement of all mixers...
phase/frequency detector
Hello, all. I am thinking of using Analog devices AD9901 phase frequency detector for a multiloop PLL design. This device shall be used in the coarse loop, stepping in 60MHz steps. I would appreciate if someone out there could share with me the following:
[1] What...
coupled line bandpass filter ads
It is not so important to get accurate circuit simulation. What is important is the result of EM simulation, such as Momentum or Sonnet which takes into account of the housing effect. Remember that the edge coupled design is radiative (open end), you need to...
coupled line filter
For Ku band edge coupled microstrip bandpass filter, they must be contained in narrow channel in order to minimize radiative loss. Try to adjust your layout such that Port 1 and Port 2 are in line => all coupled section will be slanted at some angle, with respect to the...
converting signal to baseband signal
Try "RF Microelectronics" By Behzad Razavi. or "Microwave and RF Design of Wireless Systems" by David M Pozar.
A quick answer to Question: The trend in digital domain is to digitize the RF signal as soon as possible. We are seeing more multiple bit...
advantages of using superheterodyne fm receiver
If it is a true direct conversion receiver, then there is no image problem! If you remember, image is always located at 2*IF away from the desired signal. If IF=0Hz, where is the image?
But we do have DC offset problem to solve, for example...
I heard and had seen Spurious Analysis result of microwave upconverter and receiver using MatLab Simulink. It is able to model the filters, amplfier and mixer behaviour. It seems to be graphical driven based design, rather than writing long MatLab code. I must admit I know very minimum about...

Re: How Self-resonace freq (SRF) effects Lumped ELement filt
Common "odd" things are "dips" in passband of LPF or HPF when components'SRF are near or within the operating frequency or non-ideal rejection/stopband response response
