RFHA1028

160W GaN Wide-Band Pulsed Power Amplifier

The RFHA1028 is a 45V 160W two-stage high power amplifier

designed for L-Band pulsed radar, air traffic control and surveillance

and general purpose broadband amplifiers applications. Using an

advanced high power density gallium nitride (GaN) semiconductor

process, these high performance amplifiers achieve high output

power, high efficiency and flat gain over a broad frequency range in a

single package. The RFHA1028 is an input matched power GaN

transistor with 30dB small signal gain packaged in a ceramic

package. The package provides excellent thermal stability through

the use of advanced heat sink and power dissipation technologies.

Ease of integration is accomplished through the incorporation of

single, optimized matching networks that provide wideband gain and

power performance in a single amplifier.
