Power Attenuator Calculator

Yesterday I made additions and changes to the Power Attenuator Calculator.
This spreadsheet, can be used to design Power Attenuators.

With this excellent Power Attenuator Calculator you can design attenuators of 3 dB, 10 dB or 20 dB, for any Input Power you want, which are built with good available resistors of the E12-series, with a maximum power that you can chose yourself.

I use attenuators for QSO's with very low power.
A 10 dB attenuator reduces the 500 mW from my FT-817 to 50 mW.

The new Calculator will show up later on the PA1B QRPp page, but via the Public link to Dropbox Power Attenuator Calculator you can download the calculator in advance.
Take a look and get your self a shopping list for an attenuator.

  1. Bert,

    Ik ga de 10dB verzwakker binnenkort weer eens gebruiken.

  2. Tjeerd, met een 5 watt zender of met de FT-817 op 500mW? 73, Bert
