Abstract
A zero loss bias “T” is provided for use in an RF receiver front end in order to bias a received RF signal with a DC current. The zero loss bias “T” permits a DC current to be introduced into an RF signal path of a filter having filter characteristics sufficient to pass frequencies only in a desired passband without associated losses to the RF signal. The filter may be provided by an LC filter having a ground coupling point. DC current is coupled to the RF signal path of the filter via the ground coupling point.
