NPN 9 GHz wideband transistor


Quick ordering

DistributorIn Stock
OR:  

NPN silicon planar epitaxial transistor, intended for applications in the RF front end in wideband applications in the GHz range, such as analog and digital cellular telephones, cordless telephones (CT1, CT2, DECT, etc.), radar detectors, pagers and satellite TV tuners (SATV). The transistor is encapsulated in a plastic SOT23 envelope.

Features and benefits

  • Gold metallization ensures excellent reliability
  • High power gain
  • High transition frequency
  • Low noise

Applications

  • RF front end in wideband applications in the GHz range
  • Satellite TV tuners

NXP Semiconductors' products are specifically designed and manufactured to be used within the electrical, thermal, mechanical and other parameters set forth in NXP Semiconductors' data sheets. Quality and reliability data provided by NXP Semiconductors, such as MTBF, MSL and FIT, is intended to be a non-binding estimate of product performance based upon diffusion process, history only. It does not imply that any performance levels reflected in such data can be met if the product is operated outside the conditions expressly stated in the latest published data sheet for a device or in your application.

The RoHS data provided hereunder is preliminary and non binding for NXP Semiconductors. NXP Semiconductors does not accept any liability related to this data.

NXP Semiconductors products are not designed, authorized or warranted to be suitable for use in medical, military, aircraft, space or life support equipment, nor in applications where failure or malfunction of an NXP Semiconductors product can reasonably be expected to result in personal injury, death or severe property or environmental damage nor for any other use that is not explicitly agreed between the parties.
