The device is designed in 0.15µm low noise pHEMT
process.
The devices is capable of more than +15 dBm output
power at 1 dB compression point, and provide morethan 11dB of gain from DC to 43 GHz with less than1 dB of Gain variation with an excellent group delay up
to 43GHz (less than +/- 3ps). The Design has been
optimized to provide high efficiency, supply current is
as low as 90mA with Vb=+8V.
The MMIC integrates an output power monitoring
function: a 24 dB tap coupler delivers the image of theoutput level on a dedicated pad, and a peak detector isavailable on the die. Connecting the input of the peakdetector to the tap coupler output will generate a DC
signal, at the output of the detector, monitoring theoutput signal. A reference diode is also available fortemperature stabilization of the detector function.
S2P file can be provided for system design simulation.
GDSII file is also available for mechanical design.
