Silicon Transistor
µPA834TF
NPN SILICON EPITAXIAL TRANSISTOR (WITH 2 DIFFERENT ELEMENTS)
IN A 6-PIN THIN-TYPE SMALL MINI MOLD PACKAGE
DESCRIPTION
The µPA834TF has two different built-in transistors (Q1
and Q2) for low noise amplification in the VHF band to UHF
band.
FEATURES
• Low noise
Q1 : NF = 1.4 dB TYP., Q2 : NF = 1.2 dB TYP.
@f = 1 GHz, VCE = 3 V, IC = 7 mA
• High gain
Q1 : |S21e|2 = 12.0 dB TYP. Q2 : |S21e|2 = 9.0 dB TYP.
@f = 1 GHz, VCE = 3 V, IC = 7 mA
• 6-pin thin-type small mini mold package
• 2 different transistors on-chip (2SC4227, 2SC4226)
