Bipolar RF Transistors are semiconductor devices with three terminals that are used to switch or amplify signals in equipment involving radio frequencies. Bipolar junction transistors are designed as either NPN or PNP, with characteristics of transistor type, collector-emitter breakdown voltage, transition frequency, noise figure, gain, power, DC current gain, and collector current.

Choose logic inverter ICs by thresholds, supply, output drive and delay. Compare standard and Schmitt-trigger inputs, power sequencing and replacement checks.
