BIPOLARICS, INC.
Part Number BRF504
NPN LOW NOISE SILICON MICROWAVE TRANSISTOR
PRODUCT DATA SHEET
FEATURES: • High Gain Bandwidth Product f = 10 GHz typ @ I C = 4mA t
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, ft 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 unencapsulated dice.
