First approach is to generate the high frequency directly, at the fundamental, using an oscillatortuned on the desired frequency. Few sensitive issues appears here due to high working frequency as, stability, jitter, phase noise, pulling, pushing, low output power, and cost of the active component to meet the performances

An oscillator is an electronic circuit designed to produce either audio or radio frequency signals. These will generally have sineusoidal wave form, but other wave shapes such as square and sawtooth are possible. In radio equipment oscillators will always have a low output power, and if a radio frequency is produced, the oscillator is acually a basic radio transmitter.

Is a radio beacon, whose purpose is the investigation of the propagation of radio signals. Most radio propagation beacons use amateur radio frequencies. They can be found on LF, MF, HF, VHF, UHF, and microwave frequencies. Microwave beacons are also used as signal sources to test and calibrate antennas and receivers

Kuhne electronic GmbH
From classic equipment for simple QSOs to high performance modules for contests, EME-operations and satellite radio: Our products provide absolute top performance. When choosing their equipment many radio amateurs and club-stations don't compromise and trust in the proven quality of Kuhne electronic amplifiers. Numerous contest victories, records and first contacts with a country were and are achieved with Kuhne products. Our amplifiers are remarkable for high gain and high linearity. LD-MOSFET and GaAs-FET-systems are the state-of-the-art technology in the amateur sector and enable the perfect use for all analog and digital modes (e.g. SSB, CW, WSJT, ATV, DATV). Small mechanical measurements and milled aluminum cases enable high temperature stability and tower mounting. Don't compromise and get technology from Kuhne electronic!

. Internal filters provide high spurious rejection and image rejection. Due to low phase noise and high frequency stability of the local oscillator at 3000 MHz, the up converter is suitable for analog and digital communication systems.Typical applications are Multichannel Multipoint Distribution Systems (MMDS) using QPSK modulation and DVB?T or DVB?S systems. The output power of 20 mW can be increased to several watts by the use of an additional power amplifier.

75-NS-3 -
National RF, Inc
National RF’s 75-NS-3 receiver is a complete super-hetrodyne mini high frequency receiver, designed specifically for the short-wave listener, electronics enthusiast or radio amateur, who wants to use their hands and build a radio. The receiver is offered as a semi-kit in which the electronic assembly is loaded and functionally tested at the National RF facility. The customer must then go to the grocery store (yes…the grocery store!), procure a can of lunch meat, eat it or give it to the dog, and then proceed to drill and paint the can, in order for it to become the receiver’s enclosure! As the name of the preferred potted meat can has a registered trademark by Hormel Foods, Inc., it won’t be mentioned on this web-site. However, the name of the product is synonymous with unwanted email!!! In addition, there are other food products that might be found that are packaged in the same metallic enclosure. Detailed drilling instructions and final assembly instructions are provided as part of the kit. All other parts required for completion of the receiver are provided as well. Recognizing that the finished assembly looked somewhat like the fabled Collins receiver of the ‘60s, the 75S-3, (particularly when the can is painted a light gray) National RF engineers dubbed it (with tongue firmly planted in cheek, of course) the 75-NS-3! Although we have had fun packaging this receiver in a lunch meat can, it is nothing to turn your nose at! Its performance and portability will surprise you, and it is an ideal radio to bring with you on any trip!
