Hi,

i'm relatively new in RF design and i have to deal with design of wideband amplifier. It should work from 5kHz up to 1.5 GHz. First i focused on choose of proper transistor. I found pHEMT ATF531P8, which have good parameters for my design (P1dB, NF and OIP3). But, it's designed for frequency range 50MHZ to 6GHz. I'm pretty confused, will it work under 50 MHz ?

Thanks for any advice
