Miniature Broadband Gain Stage. MACOM Technology's MAAL-010200 broadband gain stage is a GaAs MMIC amplifier in a lead-free SOT-89 surface mount plastic package. The MAAL-010200 employs a monolithic 1-stage self-biased design featuring a convenient 50 ? input/output impedance that minimizes the number of external components required. Its broadband design provides usable performance from 500 to 3000 MHz.
