The AM82223-018 is a common base, silicon NPN bipolar transistor designed for high gain and efficiency in hi-rel aerospace telemetry applications in the 2.2-2.3 GHz frequency range. It incorporates internal input and output impedance matching structures along with a rugged, emitter-site ballasted overlay die geometry capable of withstanding :1 load mismatch at any phase angle under full rated operating conditions.. The AM82223-018 is provided in the industry-standard AMPACTM metal/ceramic hermetic package.
