DESCRIPTION AND APPLICATIONS:
Bipolarics' BRF504 is a high performance silicon bipolar
transistor intended for use in low noise application at VHF,
UHF and microwave frequencies. High performance low
noise performance can be realized at 2 mA or less making the
BRF504 an excellent choice for battery application. From 4
mA to over 8mA, f_t is nominally 10 GHz. Maximum
recommended continuous current is 16 mA. A broad range
of packages are offered including SOT-23, SOT-143, plastic
and ceramic 0.085" Micro-X, 0.070" Stripline and unencap-
sulated dice.
