Summary :

This paper reports on X-band Gallium Nitride (GaN) chipsets for cost-effective 20W transmit-receive (T/R) modules. The chipset components include a GaN-on-Si monolithic microwave integrated circuit (MMIC) driver amplifier (DA), a GaN-on-SiC high power amplifier (HPA) with GaAs matching circuits, a high-gain GaN-on-Si HPA with a GaAs output matching circuit, and a GaN-on-Si MMIC switch (SW). By utilizing either combination of the DA or single high-gain HPA, the configurations of two T/R module types can be realized. The GaN-on-Si MMIC DA demonstrates an output power of 6.4-7.4W, an associate gain of 22.3-24.6dB and a power added efficiency (PAE) of 32-36% over 9.0-11.0GHz. A GaN-on-SiC HPA with GaAs matching circuits exhibited an output power of 20-28W, associate gain of 7.8-10.7dB, and a PAE of 40-56% over 9.0-11.0GHz. The high-gain GaN-on-Si HPA with a GaAs output matching circuit exhibits an output power of 15-30W, associate gain of 27-30dB, and PAE of 26-33% over 9.0-11.0GHz. The GaN-on-Si MMIC switch demonstrates insertion losses of 1.1-1.3dB and isolation of 10.1-14.7dB over 8.0-11.5GHz. By employing cost-effective circuit configurations, the costs of these chipsets are estimated to be about half that of conventional chipsets.
