f_hp = 1/((C_be+C_bj)*R_in)
This formula uses 4 Variables

Variables Used

Pole Frequency High Pass - (Measured in Hertz) - Pole Frequency High Pass is the point at which the signal has been attenuated by 3dB (in a bandpass filter).
Emitter-Base Capacitance - (Measured in Farad) - Emitter-Base Capacitance is the capacitance between the emitter and the base.
Collector-Base Junction Capacitance - (Measured in Farad) - Collector-Base Junction Capacitance in active mode is reverse biased and it is defined as the capacitance between collector and base.
Finite Input Resistance - (Measured in Ohm) - Finite Input Resistance is the finite resistance seen by the current source or voltage source which drives the circuit.

STEP 1: Convert Input(s) to Base Unit

Emitter-Base Capacitance: 100.75 Microfarad --> 0.00010075 Farad (Check conversion here)
Collector-Base Junction Capacitance: 150.25 Microfarad --> 0.00015025 Farad (Check conversion here)
Finite Input Resistance: 1.21 Kilohm --> 1210 Ohm (Check conversion here)
