Princeton Microwave Technology cascadable amplifiers is offered in TO-8 packages, TC-1 connectorized cases, and surface mount PlanerPak packages, respectively. Available with PmT R Series screening, these amplifiers are cascadable modules designed for the best possible performance under difficult operating conditions. They offer unconditional stability and guaranteed performance over the specified frequency response range and temperature extremes. Voltage requirements vary from +5 VDC to +24 VDC, depending on the model. Internally, these units contain various combinations of Si or GaAa MMICs and discreet components on alumina substrates, with thin-film gold interconnect and resistors, Since these units are cascadable modules, both input and output circuits of each device is optimized for the best 50-ohm impedance match. These amplifiers are ideal for pulse amplification, radar and avionic military systems, and high-speed fiber optic systems. High-frequency surface mount amplifiers, up to 140 GHz are available.
