Input Impedance of Dipole Antenna
... To predict the power required for the topside soundings, we need to estimate the input impedance of the transmitter, a center-fed dipole of half-length L and radius a. The equivalent circuit of the input impedance is a series of two resistors and one capacitor: ...

TDA7000 RX FM Receiver
... TDA7000 RX FM Receiver My VHF FM Wireless Microphone project became about the most popular of my transmitters, probably because it is so simple. Here is a very simple VHF FM receiver which is little more than a single IC and a "slack handfull" of capacitors. Note that an external amplifier is a real ...
