Ultra high frequency (UHF) is the ITU designation [1] for radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter).
The inductive output tube (IOT) or klystrode is a variety of linear-beam vacuum tube, similar to a klystron, used as a power amplifier for high frequency radio waves. It evolved in the 1980s to meet increasing efficiency requirements for high-power RF amplifiers in radio transmitters. [ 1 ]
Motorola T5320 FRS handheld radio. The Family Radio Service (FRS) is an improved walkie-talkie radio system authorized in the United States since 1996. This personal radio service uses channelized frequencies around 462 and 467 MHz in the ultra high frequency (UHF) band.
The simplest klystron tube is the two-cavity klystron. In this tube there are two microwave cavity resonators, the "catcher" and the "buncher". When used as an amplifier, the weak microwave signal to be amplified is applied to the buncher cavity through a coaxial cable or waveguide, and the amplified signal is extracted from the catcher cavity.
A valve RF amplifier (UK and Aus.) or tube amplifier is a device for electrically amplifying the power of an electrical radio frequency signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of ...
Mini-UHF connector, a smaller and much newer design than the standard UHF; SMA connector A 50 ohm screwed connection. The 0.9mm centre pin is the same diameter as the centre of RG402 Coax so that connections to that cable can be made with no discontinuity, forming the pin from the coax itself. Good to 18 GHz
An Australian man is accused of murdering his wife with a homemade spear. Talaat Hawatt, also known as Terrance Howot, is accused of having attacked his wife Khouloud Bakour Hawatt with the weapon ...
Available accessories include remote controls, transmit power amplifiers, antennas, and ground support equipment. [6] It has been largely replaced by the AN/ARC-210 series in U.S. systems. [ 7 ] The ARC-210 is an improved version of the ARC-182, adding jam-reisistant SINCGARS capability to communicate with Army radios for close air support.
