Wolfspeed, a Cree Company, has developed an application circuit that demonstrates the ability for the CGHV27060MP to operate between 800 MHz to 2700 MHz for tactical communication power amplifier applications. The CGHV27060MP houses a GaN die in a plastic package for added cost benefits however in a thermally viable TSSOP package. The device can deliver over 60W of continuous wave (CW) output power. This application note describes the typical performance that has been achieved and what can be expected when evaluating the application fixture.
Key features of the amplifier include:
- Frequency range 800 MHz – 2700 MHz
- Over 15 dB of small signal gain
- Over 49 % drain efficiency
- 70W typical saturated output power
- Gain flatness < 3.5 dB
