CGH55015F1 / CGH55015P1
15 W, 5500-5800 MHz, GaN HEMT for WiMAX
Cree’s CGH55015F1/CGH55015P1 is a gallium nitride (GaN) high electron mobility
transistor (HEMT) designed specifically for high efficiency, high gain and wide bandwidth
capabilities, which makes the CGH55015F1/CGH55015P1 ideal for 5.5-5.8 GHz WiMAX
and linear amplifier applications. The transistor is available in both screw-down, flange
and solder-down, pill packages. Based on appropriate external match adjustment, the
CGH55015F1/CGH55015P1 is suitable for 4.9 - 5.5 GHz applications as well.

Note:
MER is the metric of choice for cable systems and can be related to EVM by the following equation: EVM(%) =
100 x 10 ^ -((MERdB + MTAdB)/20). MTA is the “maximum-to-average constellation power ratio” which varies
with the modulation type: MTA = 0 for BPSK and QPSK; 2.55 for 16QAM and 8QAM-DS; 3.68 for 64QAM and
32QAM-DS; 4.23 for 256QAM and 128QAM-DS
