How can I evaluate this device as a detector? The most useful parameter is TSS, but it's calculation involves parameters such RF bandwidth, video resistance, noise figure, etc. We are given only two relevant parameters in datasheet, namely SSNF and gain but they are not enough to calculate TSS of this device in 1 MHz bandwidth. I can find noise bandwidth from noise figure but that's about it. Can someone recommend app notes or lecture notes that will help me determine device's TSS or similar parameter to be able to do path loss calculation.
