The transistor reactance modulator shown in the Figure is to be used in an FM transmitter. The input resistance of the transistor is 600 Ω and beta transistor is 65. (a) How much capacitance does this ...

The effect of base-width modulation on the exact small-signal, high-frequency equivalent circuit of p-n-p (and n-p-n) junction transistors is examined. It is found that (except for the effect on the ...

Reconfigurable wireless transmission systems increasingly enable a more efficient use of radio and microwave frequency spectrum and their hardware. Under such circumstances tuneable devices hold a ...
