In this blog post I lay the foundations for a high performance RF Band Pass Filter  suitable for the Irwell HF Transceiver as well as SDR receivers and other transceiver builds.

For my own transceiver project the filter module needs to meet the following criteria:

• Have a sufficient number of filters to enable general coverage reception of 0.5MHz to 30MHz and provide uniform high performance for any given frequency within this range.
  
  
• Be usable in the transmit path with an rf power handling rated at 1 watt.
  
  
• Give good suppression to frequencies that fall below or above the wanted frequency passband.
  
  
• Provide low insertion loss within the wanted passband & good return loss.
