Abstract:
According to one embodiment, a compact broadband radio frequency (RF) receiver circuit includes a low noise amplifier which includes a first amplifier stage, a second amplifier stage, an inter-stage network including a higher order filter network, where the inter-stage network is coupled between the first amplifier stage and the second amplifier stage, and a double resonance transformer network coupled to an output of the second amplifier stage. The RF receiver circuit includes a low pass filter and a mixer circuit coupled between the low noise amplifier and the low pass filter.

Claim (Index 11):
The RF receiver circuit of  claim 5 , wherein the mixer core comprises:\n a first stage comprising a first differential transistor pair having a first and a second transistor, wherein a first gate terminal of the first transistor and a second gate terminal of the second transistor together are the RF inputs to receive a differential RF input signal to be mixed, wherein a first and a second source terminals of the first and the second transistors respectively are each coupled to a degenerative inductance to enhance a linearity of the mixer circuit; a second stage coupled to the first stage, wherein the second stage comprises a second differential transistor pair having a third transistor with a third gate and a third drain terminal and a fourth transistor with a fourth gate and a fourth drain terminal and a third differential transistor pair having a fifth transistor with a fifth gate and a fifth terminal and a sixth transistor with a sixth gate and a sixth drain terminal, wherein the third gate terminal is coupled to the sixth gate terminal and the fourth gate terminal is coupled to the fifth gate terminal, wherein the third gate terminal and the fourth gate terminal are the LO inputs to receive a differential LO drive signal to drive the mixer, wherein the third drain terminal is coupled to the sixth drain terminal and the fourth drain terminal is coupled to the fifth drain terminal, wherein the third drain terminal and the fourth drain terminal are the IF outputs of the mixer; and a pair of inductive transmission lines having a first inductive transmission line coupled in between a first drain terminal of the first transistor and source terminals of the third and fourth transistors, and a second transmission inductive line coupled in between a second drain terminal of the second transistor to source terminals of the fifth and sixth transistors.
