Medium Power MMIC

DescriptionFeatures

The VWA 50014 AA MMIC is designed in 0.15µm low
noise pHEMT process.

The device is capable of output voltage up to 8Vpp andhas a saturation point above 21dBm. It covers
frequency from DC to 28GHz, and is DC coupled.
Design has been optimized to provide high efficiency,
supply current is 200mA with Vb= +9V.
The MMICs integrate 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 DCsignal, 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.

Handling
These products are sensitive to electrostatic discharge and should not be handled except at a static free workstation.
Take precautions to prevent ESD; use wrist straps, grounded work surfaces and recognized anti-static techniques whenhandling the MMIC.
