Building on indium phosphide high electron-mobility transistor (InP HEMT)(3) technology developed by Fujitsu Laboratories, Fujitsu and Fujitsu Laboratories developed a multistage amplifier that suppresses the oscillator effect while increasing the amplification ratio.
Multistage amplifier suppresses oscillator effect, increases amplification ratio
The multistage amplifier employs a cascade of four single-stage 100 MHz to 20 GHz feedback amplifiers and achieved, a gain level of 32[plus or minus]1 dB, input and output SWRs of better than 2 and a noise figure of 4.5 dB.

He demonstrates how to achieve approximate results that fall within an acceptable range of accuracy and are based on sound scientific principles for the basics such as amplifiers and transistors and yet applicable to biasing, single and multistage amplifiers, current sources and mirrors.
This is normally achieved in low frequency, multistage amplifiers by using large amounts of voltage gain, [A.sub.v], followed by a current gain, [A.sub.i], stage.
These functions include multibit digitally controlled attenuators, control devices with on-chip TTL/ECL driver circuits, multistage amplifiers and mixer/amplifiers.
This approach fails in many cases, such as in the analysis of multistage amplifiers or complex networks.
This four-port test system features the accuracy and ease of use of a two-port system to reduce the errors, time and cost of measuring transistors, multistage amplifiers, couplers, hybrids, circulators, switches, multiplexers and other multiport components.
Besides sloping amplifier gain across the band, this also can reduce drive at high frequencies in multistage amplifiers and can cause significant reduction in amplifier output power capability at those frequencies.
