Abstract

A receiver receives a wide band signal in a range comprising a front end to the receiver including a complementary metal-oxide-semiconductor (CMOS). The CMOS includes a dipole antenna that receives a received signal; a hybrid-based broadband isolation structure that receives the received signal and a local oscillator LO signal and passes through the LO signal to a sub-harmonic mixer. The sub-harmonic mixer mixes the received signal with the local oscillator signal to generate an intermediate frequency (IF) signal to the hybrid-based broadband isolation structure.
