NE68730-T1

Overview

The CEL NE68730-T1 is a surface mount NPN silicon high frequency transistor designed for low cost, low noise applications. It operates at frequencies up to 2.4 GHz with excellent performance at low voltage and current levels. The device features a gain bandwidth product (fT) of 9 to 11 GHz at VCE = 2V/IC = 20mA and a minimum noise figure (NFMIN) of 1.3 to 2.0 dB at 2.0 GHz. It provides an insertion power gain of 7 to 8.5 dB and a forward current gain (hFE) of 70 to 140. The collector current rating is 30 mA with a total power dissipation of 90 mW.
