Abstract: A RF front-end circuit and a low noise amplifier thereof configured for a receiver are provided. The circuit includes a low noise amplifier and a quadrature passive mixer. The low noise amplifier provides two RF output differential signals to the quadrature passive mixer. The RF signals are down-converted to the differential in-phase baseband signals and the differential quadrature-phase baseband signals. The structure of the RF front-end circuit can avoid the signal and noise interfering between in-phase channel and quadrature-phase channel without using a 25% duty cycle local oscillation generator circuit.

Abstract: A centrifugal fan includes a spiral housing, a driving mechanism and multiple internally mounted impellers. The driving mechanism and the centrifugal impeller, rotated by the driving mechanism, are installed in the spiral housing. A spiral flow channel is defined between the centrifugal impeller and the spiral housing. When the centrifugal impeller rotates, airflow is sucked axially into the spiral housing through an inlet opening and moves along each blade of the centrifugal impeller into the spiral flow channel. The centrifugal impeller includes a hub and multiple blades. Each blade is secured to the hub at one end and has at least one vertical convex strip or vertical concave strip at an opposite end, wherein the vertical convex strip or vertical concave strip on each of blade disturbs the airflow across thereof and reduces narrow-band noise.
