What made you select the RFHIC Corporation RDC40D10B as a featured product?
I chose the RFHIC Corporation RDC40D10B because it combines 12.6W typical output power with broadband operation from 2 to 6 GHz, spanning a 3:1 frequency range. Achieving useful RF power and efficiency over this bandwidth can be challenging because impedance matching becomes more difficult as bandwidth increases, while external matching networks add components, PCB area and insertion loss. The RDC40D10B has internally matched 50-ohm RF input and output ports, making it far easier to integrate into a broadband RF amplifier.
This wide bandwidth is particularly useful for electronic warfare and radar applications. Broadband EW architectures may need to cover multiple frequency bands within a common RF chain, while separate narrowband amplifiers can require additional switching and supporting components. The RDC40D10B integrates a two-stage cascaded amplifier into a single GaN-on-SiC hybrid module. With 25 dBm input power, it provides typically 16 dB large-signal gain and 12.6W output power under the datasheet test conditions. For the system designer, this level of integration can help reduce component count and simplify their RF architecture.
Size, weight and power are also important considerations in many defence applications. The RDC40D10B measures 8 × 14 × 2.6 mm and is supplied in a ceramic surface-mount package. It operates from a 28V drain supply and offers 35% typical drain efficiency at 25 dBm input power. Combining two amplifier stages and broadband 50-ohm input and output matching in one compact package saves PCB area and removes much of the broadband matching work from the system designer.
