This program will find all possible spurious
products which may occur when two signals are multiplied together. It also
predicts the relative strength of the products based upon the fourier series.
It searches within a fixed or tracking bandwidth. Very helpful when
you're trying to determine a good IF (intermediate frequency) for a radio
design.
This program finds spurs within a Translation
Loop or Offset PLL often used in phase modulated transmitters. It has an
automated search feature which allows it to pick the IF for you; a very
specialized program but when you need it there's no substitute.
RF Block Calc is a two stage
RF performance calculator. The user can select which parameters to solve
along the signal path, not just the final cascaded performance. You don't
have to guess at a block's NF; simply select the desired block for which you
would like the program to solve. Try clicking various blocks to change
there type and operation. It also can solve for NF, given noise voltage
from a spice simulation or datasheet. Try the "Quick Calc" dialog to
explore the effects of 1/f noise in, for example, a MOS device. The
program is incomplete but it has been tested and proven in practice.
Currently, there is no support for saving or printing. If you like the
program and would like it to be "completed," please convey your interest by
emailing me at the
address in the About Dialog box.

Updated (05/16/04). This
Excel file uses VB functions that require Macros to be Enabled.
You can view the equations by using the VB Editor under the "Tools |
Macro | Visual Basic Editor" menu (or by pressing ALT + F11). Many new
functions have been added as of 05/16/04.
Contains functions which show
up in the "User Defined" function category. Functions such as cascaded
Noise Figure ("CascNF"), cascaded Input 3rd order intercept point ("CascIIP3"),
Noise Power ("dBmPno"), convert power in dBm to Volts RMS ("dBmToV"), Voltage
Standing Wave Ratio ("VSWR"), etc.
