A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, , and generates an output signal of a frequency: f o u t = f i n N {\displaystyle f_{out}={\frac {f_{in}}{N}}}
A frequency synthesizer is an electronic circuit that generates a range of frequencies from a single reference frequency. Frequency synthesizers are used in devices such as radio receivers , televisions , mobile telephones , radiotelephones , walkie-talkies , CB radios , cable television converter boxes , satellite receivers, and GPS systems.
A dual modulus prescaler is an electronic circuit used in high-frequency synthesizer designs to overcome the problem of generating narrowly spaced frequencies that are nevertheless too high to be passed directly through the feedback loop of the system. The modulus of a prescaler is its frequency divisor.
Picture shows a typical output expected from a Wilkinson power divider. The , are almost -3 dB, and the is low near the design frequency. Picture demonstrates a very high isolation between output ports (port 2 & 3) of a Wilkinson power divider
The internal block diagram and schematic of the 555 timer are highlighted with the same color across all three drawings to clarify how the chip is implemented: [2] Voltage divider : Between the positive supply voltage V CC and the ground GND is a voltage divider consisting of three identical resistors (5 kΩ for bipolar timers, 100 kΩ or ...
A 3 dB 2.0–4.2 GHz power divider/combiner. Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in ...

In electronics, a frequency multiplier is an electronic circuit that generates an output signal and that output frequency is a harmonic (multiple) of its input frequency. Frequency multipliers consist of a nonlinear circuit that distorts the input signal and consequently generates harmonics of the input signal.
