RF power amplifier operates between 7.9 and 11 GHz
Richardson RFPD has announced in-stock availability and full design support capabilities for a new gallium nitride on silicon carbide, radio frequency power amplifier from United Monolithic Semiconductors.
The CHA8612-QDB is a two-stage high power amplifier operating between 7.9 and 11 GHz. It provides 18 W (typical) of saturated output power and 40% power added efficiency.
The integrated circuit is manufactured with a GaN HEMT process, 0.25 µm gate length, via holes through the substrate, air bridges and electron beam gate lithography.
It is versatile for a wide range of applications, from military to commercial radar and communication systems.
Additional key features of the CHA8612-QDB include:
- Linear gain: 26 dB
- DC bias: Vd=30 V @ IDQ=680 mA
- MSL 3
- 46-lead, 7x7 mm QFN package
