Abstract
The noise figure for arbitrary source admittance can be computed from the noise figure at any one source admittance and the output noise when passive one-ports are connected to the receiver input, if input admittance is known. The procedure is demonstrated experimentally at 4000 MHz with offset short circuits as the passive one-ports. The input admittance determined by mismatched noise sources agrees with network analyzer measurements.Keywords
