    Abstract: A radio-frequency (RF) apparatus includes a wideband receive (RX) impedance matching circuit to provide a received differential RF signal to RF receive circuitry. The wideband RX impedance matching circuit includes first and second inductors to receive the differential RF signal. The wideband RX impedance matching circuit further includes a third inductor coupled across an input o the RF receive circuitry. The third inductor performs the functionality of a capacitor having a negative capacitance value.

    Abstract: A hybrid matching network is suitable for use with a radio frequency transmission system having a fundamental frequency and a terminating impedance. The hybrid matching network includes a first port, a first capacitor coupled between the first port and ground and having a self resonance frequency that provides attenuation of at least a first amount of a second harmonic of the fundamental frequency, an inductor coupled between the first port and ground and having an inductance such that a parallel combination of the first capacitor and the inductor has a resonant frequency at the fundamental frequency, a transmission line segment having a first end coupled to the first port, a second end, having a desired physical length and a desired physical width, and a second port coupled to the second end of the transmission line segment and adapted to be coupled to the terminating impedance.
