The QPA1017D is Qorvo’s MMIC power amplifier operating from 5.7 – 7.0 GHz for C-band radar and satellite communications applications. Fabricated on Qorvo’s production 0.15 um GaN on SiC process, the amplifier produces 50 W of saturated output power with 21 dB of large-signal gain while achieving greater than 40% power-added efficiency.
The new Model 2180 from Empower RF is a high power RF amplifier system designed to cover the 1 to 2.5 GHz frequency range, and deliver 2 kW CW of broadband output power in an 8U, air cooled chassis. The amplifier features unrivaled size, weight, and power advantages for many test and measurement, electronic warfare, and communication applications.
These GaN MMIC power amplifiers are ideal for applications involving test instrumentation, general communications, and general radar. Two models are featured below, a 25 Watt PA covering the 2-6 GHz frequency range, and an 8 Watt PA covering the 2-20 GHz frequency range.
The MAAP-011140-DIE from MACOM is a 6 W, 4-stage amplifier in bare die form. With an operating frequency range from 27.5 to 30.0 GHz, 24 dB of linear gain, 6 W of saturated output power, and 23 percent efficiency while biased at 6 V, this power amplifier is ideally suited for VSAT communications.
Millitech’s series AMP power amplifiers are designed to obtain high output power in the 18-110 GHz frequency range through the use of advanced PHEMT MMICs and transistors. These multiple MMIC amplifier chips can be combined or cascaded for applications requiring higher gain or greater output power than standard products.
The dB-3911 power-combined TWT Amplifier (TWTA) uses two wideband, periodic permanent magnet (PPM)-focused TWTs to amplify CW, AM, FM or pulse-modulated signals. Compared to a single TWT approach, the dB-3911 provides higher saturated output power and improved harmonic performance.
