Product Description
Stanford Microdevices’ SHF-0198 series is a high perfor-
mance AlGaAs/GaAs Heterostructure FET housed in a
low-cost stripline-mount ceramic package. HFET technol-
ogy improves breakdown voltage while minimizing Schottky
leakage current for higher power-added efficiency and
improved linearity.
Output power at 1dB compression for the SHF-0198 is
+27dBm when biased for Class A operation at 9V and
150mA. This HFET is also characterized at 5V for lower
voltage applications.
This device can be used in both analog and digital wireless
communication infrastructure and subscriber equipment
including cellular, PCS, CDPD, wireless data and pagers.
