FRONT END AND HIGH FREQUENCY RECEIVER HAVING QUADRATURE LOW NOISE AMPLIFIER |
摘要 |
<p>A front end and a high frequency receiver provided therewith are described, which front end comprises a quadrature low noise amplifier as a low noise amplifier. A high isolation between local oscillators and quadrature mixers is achieved thereby, reducing a DC offset at mixer outputs. The quadrature low noise amplifier may be implemented as a differential class AB cascode arrangement of MOST or FET semiconductors. A low distortion receiver having a high linearity is the result.</p> |
