Comments on "A method for measurement of losses in the noise-matching microwave network while measuring transistor noise parameters" [with reply]

For the original article see ibid., vol.MTT-35, no.1, p.71-5 (1987). The commenter points out that equations (1), (2), and (3) of the above named work are true only if the tuner´s physical temperature is 290 K. It is noted that the derivation of other equations is needlessly complicated. In replying, the authors show that any error arising from this assumption is negligible. In rebutting the reply, the commenter notes that in some cases, the errors introduced by the assumption are not negligible.<>
