micropower cheap LNA

Hello,

I am working on micropower 433,92MHz battery powered receiver and have
a problem with LNA. I have tried a few configurations (including
cascode) but I cannot lower current consumption below 400 uA. It is
too much for me. I don't need high gain because this LNA is to be a
buffer only but device price should be as low as possible. Have you
any idea how to lower the current? I don't need exact project but some
advice.

Greetings
Leopard
