former must have adequate bandwidth to cover the
intended application. Note that most RF transformers
specify bandwidth with a 50
source on the primary
and a matching resistance on the secondary winding.
Operating in a 75
system will tend to shift the low-fre-
quency edge of the transformer bandwidth specifica-
tion up by a factor of 1.5, due to primary inductance.
Keep this in mind when specifying a transformer.
Bias to the output stage is provided through the center
tap on the transformer primary. This greatly diminishes
the on/off transients present at the output when switch-
ing between transmit and transmit disable modes.
Commercially available transformers typically have
adequate balance between half-windings to achieve
substantial transient cancellation.
Finally, keep in mind that transformer core inductance
varies proportionally with temperature. If the application
requires low temperature extremes (less than 0°C),
adequate primary inductance must be present to sus-
tain low-frequency output capability as temperatures
