DESCRIPTION: D ESCRIPTION:
The MS1503 is a 28V Class C epitaxial silicon NPN planar transistor designed primarily for UHF communications. The device utilizes diffused emitter resistors to achieve infinite VSWR capability under operating conditions. Internal inpedance matching produces optimum power gain and efficiency over the 225-400MHz band.
