2000 ... 2700 MHz

This converter was developed for MMDS applications. The S-band is converted to the UHF range 167-867 MHz. By the use of the latest semiconductors, optimized band pass filters and a SAW oscillator, a high dynamic range and low phase noise of only -98 dBc/Hz @ 10 kHz are achieved. Due to low frequency drift of typ. +/- 3 ppm within 0…+40 °C the converter may be used for all digital modulation types. Typical applications are DVB-S, DVB-T, WCS, COFDM and QPSK.

Radio frequency (RF) and microwave power amplifiers (PAs) are electronic circuits used for the amplification of low power radio frequency signals to high power levels. The most common application of such high-power RF signals is driving of transmit antennas in wireless communications. Since the RF signals are attenuated as they propagate through space, wireless coverage of large areas or wide-range point-to-point connections often require large amounts of transmit power. Another application of high-power RF signals is the generation of strong electromagnetic fields in various types of cavities, where they are used for technical and physical processes like microwave heating, plasma generation, particle acceleration, or in test and measurement setups for EMC tests and characterization of RF and microwave components. Technical applications requiring high RF power levels range from microwave cooking to the treatment and finishing of materials and surfaces as well as medical appliances and optics. The characteristic performance criteria of RF power amplifiers include frequency, RF bandwidth, video bandwidth, maximum output power, energy efficiency and linearity. With his choice of an appropriate power amplifier circuit topology and active device technology (LDMOS, GaN / GaAs HEMT, InGaP HBT, etc…), the RFPA designer tries to find the best possible balance between these, often conflicting, performance criteria, based on the requirements of a given application. For example, a Class A amplifier can be highly linear, generates little harmonics and is rather robust, but is very inefficient on the other hand. It is chosen for applications that demand very high linearity and/or very high bandwidth. In contrast, the Class AB amplifier can be made far more efficient but will not be as linear as the Class A amplifier. It is best suited for applications that demand moderate linearity and bandwidth but benefit from its high efficiency. For applications that require both high linearity and high efficiency, the Class AB amplifier can be linearized using analogue, digital or hybrid predistortion techniques. In very demanding applications like cellular mobile radio or digital terrestrial television broadcast, more sophisticated circuit topologies like the Doherty PA are commonly used to further increase the average efficiency of the transmitter chain while maintaining high linearity. Due to the scarcity of wireless spectrum and the subsequent need for efficient spectrum usage, the wireless communications field is dominated by modulation formats that impose strict linearity requirements on the power amplifier. In contrast to that, the high-power RF signal generators used in technical applications usually generate constant envelope signals at fixed frequencies and thus do not rely on high linearity power amplifiers. Under such conditions, switched mode power amplifiers can be used. By operating the active devices in saturation and application of waveform shaping techniques, these nonlinear power amplifiers enable very high energy efficiencies of up to 80% and more.
