Datasheet SHF-0186 Datasheet (Stanford Microdevices)

Product Description

Stanford Microdevices’ SHF-0186 is a high performance GaAs
Heterostructure FET housed in a low-cost surface-mount plastic
package. HFET technology improves breakdown voltage while
minimizing Schottky leakage current for higher power added
efficiency and improved linearity.

Output power at 1dB compression for the SHF-0186 is +28
dBm when biased for Class AB operation at 8V and 100mA.
The +40 dBm third order intercept makes it ideal for high dynamic
range, high intercept point requirements. It is well suited for
use in both analog and digital wireless communication
infrastructure and subscriber equipment including cellular PCS,
CDPD, wireless data, and pagers.
