Free Webcast: Mixers and Frequency Conversion

Author: 

Allen Podell

Besser Associates and Microwave Journal magazine have presented a free webcast on Mixers and Frequency Conversion. This one-hour webcast has been presented by instructor Allen Podell, and the recording is now available for viewing. Frequency conversion is a critical function in all wireless systems. A key component used to accomplish this is the mixer. Designers need to understand different mixer topologies and specifications in order to meet their system requirements. This webinar provides a brief overview of frequency conversion and introduces the mixer as the component used to accomplish this function.
 

Outline:

  • Why Convert?
  • RF System Architectures
  • How many conversions?
  • How to Convert? What is a mixer figure of merit?
  • Passive diode mixers versus passive FET mixers
  • Monolithic silicon active mixer issues
  • Comparing Mixer Specifications
  • Design Overview

dBm, dBW, dBuV Calculators

Author: 

Rex Frobenius
To use the calculator below, input a value into the field and hit the enter key. The result will appear below.
You can choose different calculations from the drop down menu.

Note that to convert from dBm to dBW, simply subtract 30 from the dBm value. For example:
30 dBm = 0 dBW, which is another way of saying that 1,000 milliwatts equals one Watt.

You may also like our dB to Power and Voltage calculators.
