This dual band amplifier utilizes LDMOS devices for 20-1000 MHz coverage and GaAsFET devices for high band. The system includes a universal voltage single-phase power supply and a built in forced air-cooling system. It exhibits excellent linearity and extreme instantaneous bandwidth and features a front-panel gain adjustment scale and built-in control, monitoring and protection circuits.            Model : MBS5O6CTT, MBS5O6CUT, MBS6C6KUT, MBS6C6KVT, BBS3O6QNQ, BBS5A7AKO
