I have a number of M57729L which are 400-420. The H is 450-470. These hybrid parts lose gain pretty rapidly outside the spec'd range but will make power over quite a wide range. The L will make spec up to 430 or so an have full power capability at reduced gain to almost 440. Probably not an answer for you.
