The ICP1044 from Microchip Technology is a Three-Stage MMIC Power Amplifier engineered for broadband aerospace and defense applications operating across the 7.9–11 GHz frequency range. Delivering a pulsed output power of 44 dBm with a small-signal gain of 22 dB, it provides consistent and high-level amplification across its operating bandwidth, supporting high-performance RF transmit chains.
Fabricated using advanced GaN-on-SiC process technology, this amplifier combines high power density with strong thermal performance to withstand demanding RF environments. It achieves a power-added efficiency (PAE) of 35%, enabling an effective balance between output power and efficiency while maintaining reliable operation under elevated electrical and thermal stress conditions.
The ICP1044 operates from a 28 V drain bias with a 40 V drain voltage and draws 220 mA of drain current. It has a total power dissipation of 75 W, supporting stable high-power operation in pulsed and broadband applications.
Supplied in bare die form with compact dimensions of 3.20 x 1.80 mm, the amplifier enables seamless integration into space-constrained or custom RF assemblies. Compact and high efficiency, the ICP1044 is ideally suited for commercial radar systems, satellite communications, aerospace platforms, and defense applications requiring wideband, high-power amplification in compact form factors.
