Expanded line up of solid-state high-power amplifiers

A new portfolio of solid state, high power amplifiers has been announced by Pasternack. The coaxial packaged RF amplifiers cover UHF, VHF, L, S and C frequency bands and are widely employed in applications such as defence, instrumentation, communications, radar, SATCOM, telecom, data links and medical devices. The high-performance RF amplifier offering includes 22 models with output power levels greater than 10W that cover broadband frequencies from 150kHz to 7500MHz. Solid state 50ohm hybrid MIC designs use GaN, GaAs or LDMOS transistor technology that offers high dynamic range and allows gain levels ranging from 40 to 60dB. The typical gain variation of these amplifiers is ±1.5dB. Some amplifier models have output P1dB levels ranging from +10W to +50W, while some devices have output saturated power levels (Psat) ranging from +40 to +50dBm. The high-power single voltage supplies which are internally regulated and the circuits are enclosed in environmentally sealed metal packages. These rugged coaxial packages withstand environmental conditions like humidity, altitude, shock and vibration and each module is designed with stainless steel SMA female connectors. Each SSPA is classified as EAR99, says the company. “Pasternack offers designers one of the most comprehensive selections of high performance SSPA’s, which focus on UHF to C band frequencies for a variety of applications in multiple markets,” said Tim Galla, active RF components product manager, Pasternack. “These high gain, high power modules utilize leading edge semiconductor technology, with the benefit of high efficiency and high dynamic range.”
