before used a types of transistor, the s-parameter must be recognize first. so that i just wan to ask in designing an 868MHz Low noise amplifier, i should use a transistor that i've choose. in the datasheet provide for the transistor BFR92A is not include the s-parameter at 868 MHz. so that do i should design a circuit to measure the s-parameter of it. the question is, how to design a circuit for measuring the s-parameter...please help me as soon as possible...regards
