High-speed, low-noise discrete N-JFET

Question asked by Samir Cherian on Mar 7, 2016

Hello, I am an applications engineer looking to use a high-speed discrete JFET (n-channel) in my amplifier application for bootstrapping. My signal frequency is around 250 MHz and would like a JFET with an Ft of around 2.5Ghz if possible. The input capacitance should be low, ( < 5pF) and the noise should be < 2nV/rTHz in the flat-band region. Do you have any products that meet (or come close) to these specs.
