High Power Amplifiers


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 HMPA and HHPA Series of High Power Amplifiers cover the frequency range from 8 to 100 GHz. New models for 2010 include 28-32 GHz and 32-36 GHz units as well as several new designs in V-Band and W-Band. A wide variety of gain and bandwidth combinations are available to provide solutions for radar systems, communications systems and other applications. Variations of the amplifiers listed in the data sheet and totally new amplifier designs can also be provided, often without an NRE charge. Most models offer single bias operation with internal regulation and bias sequencing. MMIC technology is employed in every amplifier for high reliability and repeatability. The highest power units available make use of low loss waveguide power combiners.

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.

Aethercomm Model Number SSPA 1.70-1.85-20 is a high power, Gallium Nitride (GaN) amplifier that operates from 1700 MHz to 1850 MHz minimum and is packaged in a rugged, compact enclosure. This amplifier is designed for operation in airborne environments and is used to boost the signals from telemetry transmitters. Minimum output power is 20 watts across the band at PSat. Small signal gain is 50.5 dB ± 0.5 dB across the band typically. Input and output VSWR is 2.0:1 maximum.

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.
