RF::Functions - Perl Exporter for Radio Frequency (RF) Functions

SYNOPSIS

  use RF::Functions qw{db_ratio ratio_db};
  my $db = db_ratio(2); #~3dB

RF::Functions is a lib for common RF function. I plan to add additional functions as I need them.

Returns dB given a numerical power ratio.

  my $db = db_ratio(2);   #+3dB
  my $db = db_ratio(1/2); #-3dB

Returns power ratio given dB.

  my $power_ratio = ratio_db(3); #2

Returns dBi given dBd. Converts the given antenna gain in dBd to dBi.

  my $eirp = dbi_dbd($erp);

Returns dBd given dBi. Converts the given antenna gain in dBi to dBd.

  my $erp = dbd_dbi($eirp);

Returns the gain of a reference half-wave dipole in dBi.

  my $dipole_gain = dipole_gain(); #always 2.15 dBi

Return power loss in dB given frequency and distance in the specified units of measure

  my $free_space_loss = fsl_mhz_km($mhz, $km); #returns dB
