UKWEmpfänger

UKWEmpfänger is a term that likely refers to a type of radio receiver designed to pick up signals in the ultra-high frequency (UHF) range. UHF is a designation for radio frequencies in the range of 300 MHz to 3 GHz. These frequencies have wavelengths between 1 meter and 10 centimeters.

In common usage, UKWEmpfänger might specifically point to receivers used for broadcasting services such as television, mobile phones, and cordless phones. Many wireless communication technologies, including Wi-Fi, Bluetooth, and some satellite communications, also operate within the UHF band.

The design of a UKWEmpfänger would depend on its intended application. For example, a television receiver needs to demodulate complex video and audio signals, while a mobile phone receiver must handle a wide range of channels and sophisticated modulation schemes. General-purpose UHF receivers might be used by radio amateurs or for spectrum monitoring.

The performance of a UKWEmpfänger is characterized by factors such as its sensitivity, selectivity, and noise figure. Sensitivity determines how weak a signal the receiver can detect, selectivity refers to its ability to distinguish between closely spaced frequencies, and the noise figure indicates how much noise the receiver itself adds to the signal. Advances in semiconductor technology have led to more compact and efficient UKWEmpfänger designs over time.
