UHF power transistor BLV2044
FEATURES
• Emitter ballasting resistors for optimum temperature
profile
• Gold metallization ensures excellent reliability
• Internal input and output matching to achieve high
power gain and collector efficiency for an easy design of
wideband circuits.
APPLICATIONS
• Common emitter class-AB operation in base station
transmitters in the 1800 to 2000 MHz frequency range.
DESCRIPTION
NPN silicon planar transistor in a 2-lead SOT437A flange
package with a ceramic cap. The emitter is connected to
the flange.
